I am on att wireless
I have noticed that in a low service area i get none at all.
However my wife on her iphone has 1/2 bars and my bro on his atrix also has 1/2 bars.
Anyone else having similar issues?
12/7 Update - More information on what I have attempted
Setting APNS for 4g on ATT
getting correct 4g data plan on account
New Sim cards
Replacement Galaxy Nexus
Different Roms
Stock Restore Rom
restore to default and install nothing
different radio
update to 4.0.1
Once the signal drops to almost unusable levels , the only way to get it back is either reboot the phone or toggle airplane mode. After that the signal returns to a solid 89-93 DBM. After roughly 30-60min it will then drop and I have to toggle it again. All other phones in my location have no problem including my iphone 4s with the exact same sim card.
I am in a decent location for signal. On the nexus reboot its at -89 dbm , my iphone 4s is at -87. The iphone stays that way and the galaxy nexus over time drops to -105 to -111.
Still no conclusion.
I only have problem with Wi-Fi where the reception is considerably weaker than any other device just around it.

Bars mean very little, as devices have their indicators calibrated differently. You should be comparing signals, in dBm for a meaningful comparison.
The acid test, of course, is whether you can make and hold a call, and or send/receive data.

Yeah kind of hard to gauge from bars. Nokia and motorola are known for excellent reception. Samsung not so much. They do seem to be improving on all fronts though, including wifi and gps.
Sent from my samsung gt i9250 which is in the wrong country.
I havent got too in depth with testing but its simple to see there is an issue. Everyone around me can make calls and i cant. Cell standbye taking up battery life as well and has been out of signal for a while
I'm seeing a similar issue.
When I have 2g only selected, I get 2 bars -98 asu 7. When I have it deselected I have no bars and signal is -111 asu 1.
Well ive had similar issues
Today I wiped phone and came back to initially 4/5 bars and download speeds of 4 down 1 up.
Then after about 10 min , right back down to 1/0 bars and 800 kbps down 200 up.
popped off back cover and then pulled sim , reset sim and then reboot. Again it initially came back with 4/5 bars with hsdpa. Again about 10 min later back down to 1/0 bars and a -113 dbm reading,
Then oddly enough i was in the status screen just watching it hover around -113 to -105 , it clicked to edge full 5 bars , then came back to 3G 4 bars and now at -93 dbm.
Does this sound at all normal? I havent changed location more than a few feet through all this. My wifes Iphone seems to be having 0 issues right next to me.
just watched it do it again.
Was at 1 bar went to 0 , got stuck on -113 dbm for about a minute or 2 clicked over to edge-2 -87 dbm then back to hsdpa -93 dbm
:/ i got no clue at this point
there is a video showing some of the issue

Is this at home or a place where you frequently are? If so, I would do one of two things (provided you want to keep the device):
Write an NFC tag that you can tap on your way in (and presumably on on the way out as well) that would switch you over to "2G only" (which it seems gives you a better signal), and back to 3G/3.5G on your way out the door. or...
Either write yourself, or wait for one to be written, a kernel that will throw more power to the radio (at the expense of battery life however- but if you are constantly searching for signal your phone is probably wasting a ton of battery right now anyways)...
ya i am at home.
My wife consistently gets 3 down 1 up on her 4s.
No one else seems to be having issues , perhaps mine is just defective?
this is what happens when i lightly grip phone

Maybe, but I can't think of a way to reliably test whether it is defective or not. My Samsung phones have always had lightly weaker radios than my HTC and Moto phones, and my sister's iPhone, so I will wager that it is just that in the name of battery life the radio is under-powered, which can be changed in the kernel. I was in a similar boat back when I was on T-mobile (right on the edge of service), and luckily someone had posted a custom ROM for the G1 that routed more power to the radios, and gave me just enough to hold a signal and use my wifi for data. Whatever that kernel in that ROM did, it gave me about 10 dbm difference. You might want to throw a request in the development section.
you can also try exchanging the device (if ever unhappy at all you should try to), but I am wondering if it will actually make a difference. Do you know someone with a recent Samsung phone like a SG2 (not LTE/Skyrocket) or maybe one of their Windows phones (I don't know what radios/speeds they use), to see if it gives similar results?

Ya , i was at my brothers house yesterday with no service at all.
My bro had an atrix with 1/2 bars and service.
my wife had an iphone 4 with 1/2 bars and service
and my sister in law had a galaxy s2 with 1/2 bars and service as well.
I had 0 at all.
The odd thing is , every time I reboot my phone it holds on to 4/5 bars at the location im at right now for a good 10 minutes , then flatlines.

what APN are you using? Use the same APN settings as your Sis-in-law's GS2- when my Nexus first came I noticed the APN did not match my Atrix and it would not hold an HSPA+ signal for long; I changed it to match the Atrix and speeds/holding towers has been much better. Try the APN thing.
The GN and GS2 would have the same radio chip (I would imagine), and be set to draw the same amount of power by the kernel. If the APN thing doesn't work then you might want to consider an exchange I guess, maybe it is defective
The fact that it flatlines AFTER 10 minutes (presumably after all the syncing is finished for the various apps and services) is suggestive of a sort of "demand" model- like maybe the device amps up the radio when it knows there will be a lot of need, then scales back when demand is less- or over compensates at first, then under compensates later after some sort of calibration? The ten minute thing sounds odd, but sounds like something software/firmware/kernel-based...
[Keep in mind that there is much speculation contained in that advice, the true test for defective or not would simply be another GN at the same location- as that is unreasonable we'll have to speculate. Also, if your sis-in-law comes back over, check her phone status for her signal strength (not bars but dbm and asu) and see if it matches yours. The bars that you see are a software representation of those two numbers, and can be modified to under represent the actual signal.]
I am using the default cingular 410 apn
ive been reading that if support put a 4g data plan on my phone that it could potentially cause data loss. Is that correct?
also changed to 2g only for now and have 5bars -81 dbm constant.

Not sure I follow, if AT&T made your data plan a 4G data plan, it would interrupt your service?
I think you are asking if changing these APN settings will trigger something at AT&T, and they will "bump" you to a 4G plan- in which case I don't really know, I had to jump onto a "4G" plan when I got my Atrix. I think it would never reach that point though, when you set up the new APNs, that step where you touch the dot to select the HSDPA APN, it would default back to your cingular 410 apn if it were not able to connect (via SIM provisioning or whatever). If unavailable it wouldn't be connected at that rate to begin with.
How old is the data plan you are on (is it prior to the tiered plans)? If you are worried about the connection (APN) not matching the SIM, you could request a new (4G) SIM. Maybe stop in your local store, or call customer service and tell them you are thinking about buying a 4G phone, your friend's brother's uncle' pizza delivery boy's nephew has an unlocked phone you could test speeds with, could they switch out your old SIM for a newer 4G one to see if it will be worth your while at your house, then just pop in that new SIM, change the APN and away you go? (Or to be even less complicated take your old phone in with your old SIM, and just ask for a new SIM card, that yours isn't working right, and it should be a new 4G (not LTE) card...
Well, at least the phone is usable on the 2G band for you, and will save a lot of battery. Meanwhile we'll try to get you connected to an HSPA+ tower.

thanks for all the help really appreciate it.
Anyways a few things have happened since I last posted.
I had an iphone for the last 3 years. I went into ATT last week and got a normal 4g sim card in advance. Today I called my buddy who is a manager at a corporate store and he checked my account. Found that the lady had the wrong data on it. He ended up setting the sim to the 4g plan etc (which is unlimited)
I was able to add the ATT HSDPA apn and successfully connected to it. Prior to this I actually installed modaco's rom and restored everything.
At this point I am getting consistently 3 bars in my house (which is more than my wifes iphone 4s) on 4g.
Seems to be working much better now. The only other issue that remains is when I turn on WIFI. If i turn it on the cell reception goes to 1 bar or sometimes 0. I dont have the exact dbm values right now unfortunately. Calls and text still seem to go through however. Is it possible the wifi is drawing power designated for the radio?
Thanks again !

Awesome, glad it worked out.
And possibly yes, depending on how the kernel relegates power wifi could "commandeer" a little from the cell radio, and reduce the dbm just enough to reflect in the "bars" algorithm.
perhaps a new radio will eventually come out that I can test.
either way seems to be at least in service now , signal definitely drops when i hold the phone but as long as I can make calls it should be fine.

in the meantime i'll suggest using the open signal widget https://market.android.com/details?id=com.staircase3.opensignal&hl=en
which will tell you the real reception in the phone, and see what you are getting behind those bars
don't expect to make a good call when the signal drops to -90 dbm and above
and if you have multiple phones like i do, then you can compare if other phone in the same spot, connected to the same tower, is having higher or lower dbm than SGN
for example my Nexus S had worse reception than my Milestone XT720.... go figure

Thanks I will try it out,
Overall i dont think the issue is fixed at all now. Went to bad and signal dropped all the way again. Stuck at -111 dbm. I held the phone i saw it switch to edge 5 bars and then click over to H 4 bars.
I really believe its some kind of software thing. If I cycle airplane mode on / off I get 4 bars (unknown dbm but its working) of 4g service. I know the service is here and working as my wifes iphone is fine but something is causing it to not hold the signal and eventually drop and not recover.
Makes no sense
Downloaded the app ,
Was at 42% signal strengh, I noticed when I picked up phone and lightly held it , it dropped right on down to 5% and got stuck there. This wasnt death gripping it either , barely holding it. Does anyone else have this issue or is it just mine? I know all cell phones have this issue but this seems excessive , worse than my iphone 4 ever was. I then cycled airplane mode again and signal strength went right up to 65% again -89 dbm
My gsiii for some odd reason loses 4G and sometimes even service. Last night when i was on a call, it dropped and the signal reflected that i was running on edge then it switched to someting that said "G." I looked at my brother's siii and he was also on edge. So i tried putting it on airplane mode however it would not go through. It's as if i never pressed anything. So i had to restart the phone and it was on airplane mode, so i took it off then about a minute and a half later i got 4G back. Today when i was browsing the web, i randomly lost 4G again but this time i continued to have signal just no data. About a minute later I got it back. About a minute later i lost it again and regained it about a minute later. I havent noticed anything else about the phone and ive had it for about a week and last night was the first time that i restarted it. Any ideas? Has anyone else experienced this? Thanks!
I'm also having the same problem it just happened to me today also and happened the other day when I restarted phone it did nothing then I did airplane mode that didn't do anything so I clicked the enable packet data off then on an item came back in hoping it's not going to be a hardware problem cause I've dropped calls for no reason and had no service or bars were showing but had no edge 4G etc

Yeah it's really weird, when I was using mt4g, it would do that randomly as well, I'm not sure if it's a phone or a network issue. Anyone else experiencing this random drop in data?
Same here I think it's a common issue with tmobile devices.

I just moved from Sprint to Tmo and I'm getting the same on my S3. It would look like i have good 4g coverage with 3 bars then all of a sudden it goes to Edge. So I have to wait for it to go back to 4g to start surfing. Edge is like 15kbps for me which is not even modem speed which is 56k. If I accidentally start surfing on Edge it seems to wanna stick to Edge until I close whats using data then it will eventually go to 4g. But when I get 4g its awesome and I get over between 6meg to 12 but only 40% of the time. I called Tmo and they said I have great 4g coverage where I'm at....ya sure.

I've only experienced outright loss of signal once, which was last night. So far nothing else has happened really. It was just odd that my phone won't even go into airplane mode until I rebooted the device.
Same thing happened to me. I was actually quite worried and about to send my phone back. Everything seems to be working okay now. No issues.

this has driven me mad for the past few days. recently I upgraded to a S3 and my dad got a S 4G (which was released 2 years ago). while we were in Costco, my S3 randomly switched to Edge while the S 4G has 4G all the time. ALso we were on vacation to San Francisco so I could experience "Tmo largest 4G network." While we were in a hotel in Fremont, my S3 again switched to Edge and back to 4G randomly while the S 4G had 4G. also the signal is not stable at all. sometimes(1 or 2 times) it even dropped to zero bar. SOMETHING wrong with samsung phones. I read somewhere someone had this issue with the S2 also. I can live with the HSPA+ for 2 years, but hey dont give me random Edge like that
I plan to go exchange for a new phone at Costco... probably a new S3 to see if the issue still exists...

T-Mobile's 4G network works in a interesting way (do all HSPA+ networks work this way?). They idle in UMTS mode (3G) until there is network activity, and then switch to HSPA+ (4G) mode. The network changing is an automatic thing does to save battery life ("Cellular standby" is often the largest battery drains).
Ever use an AOSP-based ROM (i.e. Cyanogenmod)? You'll sometimes see the network indicator in the status bar switch between 3G to H+ to 4G, etc as you use it. Stock T-Mobile ROMs are hard-coded to always say "4G", but if you go to Settings → About phone → Status, you can watch the network type there change as well as the phone does anything over the cellular network.
You should never be dropping to GPRS or EDGE. Perhaps the mechanism described is defective on your phone?
Happened again today. Had signal but no 4G, not even Edge, just bars. i think it happens whenever the signals low. Thoughts?
I'm having the same issue at my work place. I'm getting Edge (50-80%) more often at my desk, when previously with my SGS2 it stayed at 4G all the time. Checking Cellstandby I am getting 31% time without signal.
Is there a setting to force 4g connection?
My office is in Cupertino, CA and reception is not bad in general, but there are a few locations with 4G dead spots.
I'll check my reception again at home (Santa Clara, CA). I can do a side by side comparison with my SGS2 (now belongs to my wife).
On call with TMO right now, they are going to do a reset of the phone in their system, then I will need to do a reboot. Fingers X'd that things will improve.
BTW, what options do I have to get a replacement phone if I bought mine from Walmart? Do I need to send it in or can I do an instore exchange? Just got it on Sunday. Will I incur any fees if I returned the phone?
---
Reset didn't work. Passed on to level 2, there submitting a service request to check reception in the area. Need to follow-up on Friday if the reception is still bad. Since I'm in Cali I do have 30 days to return the phone.
I have similar reception issue but I dont lose signal completely. I will go from 4g(hspa+) to 3g to edge then it will switch back to 4g after 30secs-60secs. Quite annoying since I will be stationary and it will happen and it happens more when Im in a car. Never had this problem when I had the Nexus One.

Question. With your s2 what happens if you're in an area without 4g? Do you get edge?

I am having the same issue. I had perfect 4g coverage all over my town, (I live in south texas). The problems started 2 days ago, when I lost all 4g coverage. I took out my sim card and placed it back in and the 4g logo came back on. But now I have been noticing that my cell signal will completely drop and then slowly come back up. This has happened several times. I also went to tmobile and changed my micro sim card and the issue remains. AND NOW I AM ON EDGE!!!!!
Has anyone been able to get a replacement and did it fix the problem?

So I was enjoying a cigar with a buddy who is a field tech for a Canadian carrier (not mine rogers, but another one) when we got on the topic of a samsung tablet work issued him.
He said he uses it to troubleshoot LTE issues they've been having.
Basicly the device loses LTE and either goes into "no service" or get's stuck in HSPA+.
I freaked because i've noticed the same issue, but thought it was related to CM10 running on my phone.
Apparently they discovered it has to do with they're infrastructure. The phone loses LTE, tries to re-negotiate,gets rejected, and stops trying.
They're work around is to get firmware updates to get the devices (he didn't mention which ones) to re-negotiate a second (or third time) where it almost always goes through.
I just reboot or bounce air plane mode and it often works.
Just figured people might find that interesting.

Bell has had the same issue (for a while), I haven't received any calls about it recently but also didn't receive an email about it being resolved but it appears so. Our temporary resolution for it was to just keep it at H+ for the time being

So I was enjoying a cigar with a buddy who is a field tech for a Canadian carrier (not mine rogers, but another one) when we got on the topic of a samsung tablet work issued him.
He said he uses it to troubleshoot LTE issues they've been having.
Basicly the device loses LTE and either goes into "no service" or get's stuck in HSPA+.
I freaked because i've noticed the same issue, but thought it was related to CM10 running on my phone.
Apparently they discovered it has to do with they're infrastructure. The phone loses LTE, tries to re-negotiate,gets rejected, and stops trying.
They're work around is to get firmware updates to get the devices (he didn't mention which ones) to re-negotiate a second (or third time) where it almost always goes through.
I just reboot or bounce air plane mode and it often works.
Just figured people might find that interesting.

When I bought my S3 at the Bell store here in Québec city a few weeks ago, the salesmen insisted on NOT giving me a LTE sim card.
What he told me conquers with what you are describing.
I accepted is suggestion and got a H+ micro sim.
Since then, I returned to the store to get a LTE sim card and I did encounter the issue once or twice.
I am now forcing my phone to remain on H+ at best via Settings > Wireless & networks > Mobile networks > Network mode.
In the greater HRM (Halifax/Dartmouth/Bedford) we have a pretty good LTE footprint according to the Rogers website, but my S3 is constantly reconnecting. I can tell because every time it drops LTE, my visual voicemail app will notify that it has no service.
I turned LTE off because it was just hammering my battery. I could barely make it through a 10 hour work day with little to no usage if I leave LTE on, and I'm supposedly in the middle of the service area.

Off topic: CM10 has awesome battery life with LTE i find
I first read about LTE causing loss of service several months ago. I returned my first SIII because of it and the replacement phone would also loose service randomly. So now if I want to be assured that my phone is working when I really need it to, I have to disable LTE. Seems like more people need to know this since for some people it is important to know that your phone hasn't just decided to go into NO SERVICE mode without warning.
I'm told service providers were, until recently, strongly denying there is any such problem with LTE. It wasn't until the iphone5 came out with the same issue that this became a real problem for customer service.

Not sure if this is the same issue, but I sometimes receive a "not registered on network" or "sim not registered" when phone switches from LTE to 4G or comes back after being in a no service area.
A tech calls me once a week to track the issue and he told me last week they put out a fix for eastern canada and will soon do the same out west if it works. This is Telus by the way.
If you are running into what I mentioned all you have to do is switch to GSM/HSPA Auto mode under - settings/more settings/mobile network/network mode.
Of course you won't have LTE but its a reliable temp solution if you require consistent service.
MTS LTE
I've heard similar from MTS about their LTE!
My Galaxy S3 works fine on LTE, but my brother's S2 LTE never seems to display LTE on the screen, just says 4G all the time, yet speed test results indicate it really IS LTE! The first 2 weeks, his phone kept dropping to NO SERVICE randomly, but more often than not! We swapped out the LTE SIM on day 2 since the first seemed to be defective. After that, I updated the S2 to the latest release OS which seemed to have remove SOME of the issues.
From what I've heard, the LTE towers need the phone to be quiet on network activity for 20 seconds or so before it will attempt to jump back onto LTE. The S3, being much faster, doesn't seem to have issues flipping around as it needs. I'm told they are deciding which software/firmware to upgrade their towers too which will hopefully happen early 2013!
So I'm wondering if this might be the same issue with other carriers, where the problem is ACTUALLY with the towers and not devices?!

Not that stupid as I, like I said, did experience the issue since I got my LTE sim card.
But to answer your question, no I did not have to pay for the new sim card.
I've done the same. I find "4G" fast enough for the most part, so I just leave LTE off for the gain in battery life.
Also in Halifax I might add!

I have the same issue. I'm in the SF Bay Area and even though TMobile's site has where I live and work as dark green (excellent 4g) I am lucky to get even one bar. Half the time I get network errors. Anyone else with TMobile experience anything like this? Any chance it's something that'll get resolved before my 30 day return period ends?
do any of you have other tmobile phones to compare signals with? if so, do that and if there are major differences talk to a tmobile store about getting a replacement.
these might be isolated incidents, because the majority of people are getting fully functional units

im in SF bay area (mountain view)
my data speeds are *top notch*.
you are either in an area thats out of tmobiles footprint or have a defective unit.
best bet would be to wait till tmobile actually gets the GS4 on display in the store.
when they do, go to your nearest tmob, and do a speedtest.net comparison with the demo model, and yours. if they are similar, then your part of the bay is legacy; if there is a big difference; 3,4 5 etc megabit difference; your unit may be worth exchanging for a new unit.

What part of SF are you experiencing this? My GF lives by the ballpark & she won't switch with me if she gets ****ty service.
I have excellent reception (bars) on my S4.
Way better than my Note II.
I let you know. When I get my phone next week. I do a speedtest and a screenshot of the phone signal in the settings menu.

Still no signal inside my workplace. Will do more tests. It does seem the signal is more stable, but it's only been a couple days.
Also, 4G LTE flashed for a couple seconds at my house. I live in the D.C metro area. Nice.
I have the HTC One in the Phoenix market. LTE is difficult to find more than a few bars on. 4G HSPA+ has been very easy to get full bars on.
I'm somewhat convinced T-Mobile is still working on building out in even LTE and re-farmed markets.
Sent from my cm_tenderloin using Tapatalk HD
Its funny how T-Mobile improves their network and yet many years later I still don't have service in places where I had no service maybe 5-6 years ago. And on top of this I noticed even more dead spots. I think T-Mobile should be working on that along with building penatration.....I would much rather have 3G everywhere then LTE almost nowhere.
Lately it became very frustrating since my wife has no service at work, i have no service at work, and i recently moved to different location and still no service....and God forbid I loose my wife in the mall, I have zero chances of finding her because no T-Mobile service inside.
Just got my S4 today and did not realize theres LTE where I work (fremont) which I never saw on my note 2. Even went out to lunch and was still getting LTE the next street over. So just to test I'm now back on my note 2 and it is not picking up LTE at my work. That tells me the radio on the s4 is much better.

yea its something with the S4's phone/modem. I get bars and shows signal strength of 3 to 4 bars and i can make call but no internet in certain areas all around Los Angeles County/Orange County/Las Vegas/NYC. To test it i had my buddy go with me with his LG L9 and my buddy with his LG L9 phone would work fine on the calls and data/internet meanwhile my S4 would only get calls but no data as if it was a deadspot. i would have to go around like 1/4 or so before it would work again. its really strange not to mention annoying. I noticed this started happening to me after i upgraded from MDB to the MDL baseband and after i unlocked the phone using the "debug service menu". i wish i knew someone else with a stock TMO S4 to test my findings out more. I also cant wait for more tmo S4 modems. ive been thinking of ODINing back to stock MDB to test my theory, but i have just been lazy.

i think it was a TMO LTE tower upgrade issues. after doing the Settings > More networks > Mobile networks > Network mode > and switching between the WCDMA and GSM one or the other now will work. better to have some internet than no internet, weird how the S4 just wont switch over to the working GSM internet if WCDMA fails....i guess when they coded it they figured if u have bars it "should work in theory" but they were wrong ...personally i think this should be considered a "bug"
I thought I was the only one. I found that if i keep my diztronic tpu case on while in my pocket it destroys all signal for some reason. I take it off and its fine.

I further tested my theory and went without my case all day. It didnt appear to do anything different at all. I am on CM10.1, I think I might go back to stock for awhile to see if it changes the fluctuating signal issue.
Just curious on how everyones signal is and which baseband they are on?
I'm on M919UVUAMDL and I have seen up to 15% of no signal while my S3 had 0 signal loss in a regular day.
Hi,
I've been having data issues with my HTC ONE M8 on Straight Talk for the past couple of weeks. the data service for some reasons got really iffy. before everything was absolutely fine. now sometimes I cannot access data at all, sometimes something is working and something doesn't.
when the data doesn't work:
- most of websites are not reachable
- google.com seems to work normally
- google maps might work; sometimes very slow, sometimes not working at all
- ookla speedtest won't start, but if I set a fixed server it might work
- facebook.com might work in the browser but the app doesn't work
- refreshing the page seems to help
on WI-FI I have absolutely no problem. everything works fine.
phone and txt messages work without problems.
on 3G (HSDPA) everything seems to work fine. I see problems when on LTE.
anybody has the similar issues?? any suggestions?
many thank!!
I am having the exact same issue! So frustrating, I don't want to use 3g if we should be on "Full speed 4G LTE for up to 3GB"!
tried so many different APN's, no luck can't get over 2.5mbps with any of them
I would be happy with anything that works right now. the service is just NOT WORKING. I am paying for a service that doesn't work and that's not acceptable.
I opened a case with the help desk; useless. I was talking to people who don't understand the basic concepts of networking. made me add a proxy to the APN; no difference at all.
then I put a complain on Twitter and got some other people "helping" via email. at least they asked for the address of where I am always having problems; hopefully, they check out the service at the antenna. I think it's not a BTS (antenna) issue but something related to their proxy, firewall or network gateway since google.com works without problems!
I talked to a friend of mine who has StraightTalk as well and he said that he had the same issue last year!
I had the exact same issue with Net10 it is so annoying and unacceptable =(
Have you tried calling straight talk a call
U can try this from what I know ur phone gets chooses the strongest signal tower example u are around 3G tower it has a 9/10 signal and the 4g tower is a 6/10 strength it goes with the 3g hope this helps in ur dial pad dial *#*#4636#*#* then Phone Information....Scroll down a little bit to Set preferred network type. I was able to lock in LTE only doing this and gave me the fastest signal on my device hope with works for u. If u can post ur original settings before u change to lte option only on this post so u can always revert to ur original setting good luck.

if I lock it to 3G it actually works well. I will try your suggested settings.
on another note I wonder if it's an issue with the phone radio implementation. my Nokia/Windows phone sees LTE very very slow but it doesn't stop working completely.

Hmmm Idk but anything's worth a try what settings do u have it on already?
if I put it on GSM/WCDMA (so no LTE) data works fine in 3G.
and if I do a speed test in 3G it gets about 5Mbps in download vs 1, 2 or 3 Mbps when LTE works (ZERO otherwise)
The exact same thing started happening to me two or three weeks ago. More often than not, the LTE connection simply doesn't work, and when it does, it's excruciatingly slow (anywhere from 0.01 to 2.50 mpbs, and usually less than 1.00). Do you guys have AT&T or T-Mo sims? I'm starting to wonder if going to Cricket would solve the problem, but since I'm running an AT&T sim, I'm not sure if anything would change since it's on the same network.
Straight Talk support is worthless... they think a factory data reset will fix it, when it's clearly a network issue. I just told them to stop right there and started troubleshooting myself. That's a good tip about dialing *#*#4636#*#* and turning off LTE that way. It seems like that is where the issue lies - I'm having good luck with HSPA; it's slower than LTE should be, but at least it works. It'll do as a stopgap through the end of my billing cycle, at which point I can decide whether to go somewhere else or get by on HSPA until they fix whatever the problem is.

tried and on pure LTE it simply doesn't work. the only way is to set GSM/WCDMA and it goes at 3G speeds but at least it works.
the funny part is that Google.com always works, whatsapp works, googleplay works. so it seems a problem with throttling or filtering to me.

I have ST on AT&T.
a friend of mine with iPhone 6 down in Newport has no problems. he sent me screenshots of speed test at 15Mbps.
I really wonder if it's some radio firmware issue...
Ironically, I ran into something very like this too recently....I was on an at&t straighttalk sim...lte had been OK prior to me updating to 4.4.4. It was never spectacular, but it was, at least, lte speeds. After the update I noticed it had become really sketchy...just as described, pretty much; even when mine worked it was trash. 3g was much better and totally stable. I thought it might be the update, but long story short, it wasn't. I inserted a friend's sim from tmobile and got full lte with no issues.
Now, in my case, I had been using a shaved down microsim rather than a nano sim, so I thought, maybe that's the issue. I noticed when ordering the new one, the tmobile one actually said htc m8 compatible on the page(plus my friend's legit tmobile sim got good signal and lte so I thought that's a good basis for comparison). Got the new one, put my number on it, and voila! I'm getting on average 20mbps lte. And it's very consistent too. So now I'm on the tmobile straighttalk sim and everything is fine.
Anyways, it's only $7 with free overnight shipping, so that's something easy to try. This wouldn't be the first time a new sim fixed all sorts of weird data problems with straighttalk either. I've been on with them for several years now and this is probably my 4-5th sim I've had to get for various reasons.
So, anyways, your mileage may vary but that fixed it for me. Hope it helps.

it seems ST on T-mobile is not having the same issues as ST on AT&T. the problem is that T-mobile coverage is not so good in my area.
I tried my phone in a different location (400 miles away) and had the same issues.
I've done some more testing.
it is really weird that Google.com works flawless while any other site seems not to work.
activating "save data usage" in Chrome seems to help. however it doesn't solve the problem. sometimes pages needs to be reloaded a few times.
even when LTE works, the OOKLA speed test gives me 2Mbps in dowload and 5-6Mbps in upload. so no matter what, I am better off with 3G.
I found an interesting thread here on XDA. I am not rooted at the moment and can't try.
<<
If you are rooted there is simple FIX, simple disable FD8 (Fast dormacy 8)
ro.ril.enable.r8fd=1
ro.ril.enable.pre_r8fd=1
Change both to =0 and issue will be fixed.
If your not rooted only fix is to keep HotSpot enabled than data connection wont break.

I tried the hotspot trick but it doesn't work for me
Sorry to bump an old thread, but I just wanted to give a brief update. My LTE issues with Straight Talk went unresolved for about 6 weeks despite multiple conversations with customer service. I experienced this in Raleigh, NC, Greensboro, NC, and Virginia Beach, VA. Then for Thanksgiving, I went to New York City and New Jersey (the part just outside of Philly), where all data connections were unreliable. Yes, that means 2G, 3G, HSPA, and LTE were all spotty at best the entire time.
I ran out of patience after that, and since my billing cycle was ending on 12/4, I switched to Cricket when I got home. As soon as I popped in the Cricket sim card, everything started working flawlessly again. Cricket does limit you to 8 mbps down, but that's good enough for my purposes. The issue, if it's still going on, is with Straight Talk and not the phone.
Lollipop Fixed the Issue on my HTC M8
Hey all,
I've been following this thread as I too had issues with LTE on my HTC M8 using StraightTalk. When I first got my phone, it worked perfectly with LTE on ST. Then I ran the OS update that was released sometime near November. That's when I noticed the problems. I could run a search on Google but any webpage I would try to connect to would not load. The phone would hang and eventually time out. Your instructions to turn off LTE was great help. Pages load perfectly provided LTE is not used. I was getting really frustrated and you kept me from throwing my phone at a wall. Thanks for that.
So that brings me to this post. I updated my phone to Lollipop this morning. Thought I'd give turning LTE back on and bam.... works perfectly. I've been testing it all morning and so far, all pages load really fast. I will keep an eye on it for a while and post any updates but thought I pay it back a bit with the good news since you guys helped me.
Thanks again.
AC
thank you for sharing!!
trying to upgrade to Lollipop. unfortunately I am having an issue with the recovery (flashed from TWRP to a stock that doesn't work with the OTA and can't flash any other recovery -not sure what's wrong).
when I solve this issue and able to upgrade to Lollipop I will share my LTE test results
