Can't get good mobile speeds - G3 Q&A, Help & Troubleshooting

I'm making this thread as I have a very hard time trying to find a solution on my own, I've read from these forums a lot in the past but this is the first time I make an account and post something.
First the problem: I have bought an used LG G3 phone that was bought with my carrier (personal, is from Argentina), once I got home I only used it with wifi and then flashed fulmics 5 and updated it (since I've read a lot about the phone before buying and found that the stock rom is very bad with battery, plus I really liked the rom as far as I've seen about it) and then flashed it again because I didn't select the options I wanted the first time, in both cases I've wiped data and did just about everything indicated in different tutorials, I've used twrp for flashing. After all that I've asked for mobile configurations to my carrier and at the next day, I asked my old man (the line is at his name, because of employee discounts and all that) to activate LTE for my line (I've never had a phone with LTE and with my carrier that needs to be activated in the line) and after following indications such as rebooting the phone, I decided to test my mobile speeds with LTE and they were incredibly slow (under 0.05 Mbps both up and down) and today I checked again with full signal and had the same results (give or take a couple of bps), I also installed a new kernel called xceed and tried again with no change in results (I don't know if the kernel would affect this, but I mention it just in case), and since I had my parents around at the moment, I made them try (same plan, same carrier, diferent phones) and both got normal LTE speeds (20+Mbps down, up varied), the weird thing is that my speeds are about the same with 3G H+ while wifi works normally, mobile signals are normal, even getting full bar during some of the tests, I have double checked more than a few tiems and I have the apn correctly set and all that. I don't think it could be the SIM since I've been using it with fast 3g speeds in my moto G before without a problem, but I'm still going to request a new SIM to my carrier just in case.
Short version: I've got unde 0.05 MMbps up and down in LTE and HDSPA.
Specs and all that:
- LG G3 D855 16GB version
- Carrier: Personal (Argentina)
- Data plan: unlimited speed, 500MB at a time, refreshing costs part of my credit and I've checked, I haven't surpassed my data cap, I'm far from it.
- Software: Fulmics ROM 5.3 and xceed kernel running 6.0 Marshmallow
- Emotional state: mixed feelings, it sucks to not be able to use mobile internet and the poor battery life but at the same time this is my first high end phone and it feels awesome.
I hope someone can point me in the right direction as I'm lost like an old-timer in the dance floor.
Extra info: I'll try flashing the rom again, but I would like to try different solutions first, there are some things I don't like to set up over and over, plus I want to know what could be the reasons, the very few people I've found on the internet with the same problem (excluding people talking about carriers from the US) had a case of a bad SIM card.
UPDATE: well, this is awkward... it turns out it was my plan, I checked once again and my data had to be resetted, now it works, 6mbps down and 1.3mbps up, it's not as fast as it should be but it works now. Sorry for the useless post

[Q] 2G Signal only, enabling 3G drops signal totally.

Hi everyone,
I have a generic unlocked desire 2.2, unrooted, as standard as they come and connected to Orange.
When I run on GSM only mode in network settings my phone is fine...
BUT..
Enable WCDMA or WCDMA auto mode.... and it will connect to 3G for about 10/20 secs then drop the whole lot, "emergency calls only" is all I can get.
I live in town with full 3G,and have tried at my girlfriends 100 miles away too. This has been going on for about 3 weeks, and so far I have.......
Hard reset a couple of times....
Had a new SIM from Orange...
Tried a different SIM (O2) in my phone - which works perfectly, sat browsing on H for about half an hour or more with no problem.
Tried my SIM in a different phone (Touch Pro) - works perfectly as well! 3G and browsing internet all fine.
So - Orange say its the handset.... and I'm not sure their 2nd level tech really exist, cos I've never got to speak to them or had the promised callback!
and HTC reckon its a network issue.
I can see both sides, but that doesnt help when your stuck in the middle with sloooooow internet.
The only other thing I can think is that Orange dont like the fact I'm on unlimited data and using it, I hit about 900mb a month normally and 2Gb in Nov when my home broadband died for about a week. perhaps they have blocked my handset from 3G? If so they havent told me though! I have one of the panther tariffs from mid last year which were "unlimited".
Any suggestions would be very appreciated!
Thanks in advance
Chris
Sounds strange indeed......
Theoreticly speaking, they could have placed some sort of a limit on your account to reduce the load on their network, but It'll be hard to prove. (Maybe you know someone who works there???)
You can look for your plan's contract (or ask them to fax it to you) - maybe it states the minimal speed of connection....
Threaten to disconnect if your speed does not improve..... Realy can't think of anything else.
EDIT:
Try this http://forum.xda-developers.com/showpost.php?p=10865272&postcount=5
Thanks,
I have tried all the options in that menu with no success.
Eventually last night I got orange 2nd level tech who was equally confused and could only suggest a radio version conflict with my handset and network.
Anyway they gave me a fault code which CPW (I purchased from mobiles.co.uk) looked at and glazed over.
I have called HTC direct now and they are having it in for warranty repair. 10 days with my old touch pro... how bad can i be?
Wouldnt surprise me if they send it back NFF........
fingers crossed!
EDIT: THE TOUCH PRO IS AWFUL!

Using T-Mo SGH-T989 on Mobilicity in Canada, a few questions..

I wonder if anybody is using this phone in Mobi here in Canada, a friend of mine got one and the first thing we noticed was that it takes FOREVER to pick the signal, even u do a manual search is painfully slow to stick to Mobi's network, also the Wifi spot is locked, and so we wonder if anybody knows a way to work around these issues without rooting (at the moment !!!).
Thanks for any input!
Btw, the phone is great, thin, light, no way that crappy mapple mockup will be even close, I mean, it does even come with Si....I mean Voice command, which works amazing!
I don't think there's another radio out yet so, i think the radio searching issue you're having isn't fixable?
I haven't heard anyone complain about the signal search so maybe it's your area or something with your particular phone. Try setting it to WCDMA preferred/only. Also, call into Wind and ask for a network reset.
Also, it seems like the wifi-spot is locked down by the t-mobile ROM. I doubt there's any fix for that other than rooting and installing a non-crippled ROM. I stand to be corrected though as I have yet to get mine in.
I know on mine when I do a Factory Reset it does take a minute or two to find the Mobilicity signal, but then it locks on, and is fine when I restart the phone. No work around for the Wifi Tethering unless you root and freeze the Tethering Manager. Sorry.
it works, i'm using it on Wind as you can see
just set the phone to look for WCDMA only as mentioned above, and it will bypass scanning the Rogers, Bell, Telus signal
so you get the Wind and Mobi towers to show up quickly that way
Funny you have the same problem as couple of other guys here (including me):
http://www.howardforums.com/showthr...-S2x-unlocked-Wont-find-network-automatically
My response remains the same:
It's definitely a problem with Mobilicity not your phone. It happens to me too when I boot up the phone it says "No Service" even though I previously registered with Mobilicity network and phone setting is set to register automatically. Don't worry. Boot up the phone, do nothing and wait for 2-3 minutes and see what happens. I usually have to wait 1 minute or so for the phone to auto-register to Mobilicity, not instant.
Also, in your mobile settings, set it to "WCDMA only" instead of the default "GSM / WCDMA auto" because Mobilicity uses WCDMA bands only. It may speed some things up.
Also, if you want to speed things up even more, go to your dialer, dial *#*#2263#*#*, select "WCDMA Band Preference", and then select "WCDMA 1700" so that the phone looks by default in the 1700 band (the band the Mobilicity uses exclusively).

This is not true.
You can root your phone, use Titanium Backup (paid version) to freeze the system app called "Tethering Manager", after that you can do wifi-hotspot with no problem. T-Mobile uses that software to block this feature.

this is interesting
in WIND i do not have that problem
i power on the phone and it automatically picks up the WIND tower by itself during boot time
so by the time you see the lock screen, it already says WIND Home

In the (Howard Forum) thread that I linked to, a lot of people are having this problem with registering this phone with Mobilicity. And I can personally vouch for it that every time phone boots up it takes an additional 2 minutes before you see Mobilicity.
Thx guys, so I was rt about switching the AWS setting, still it bothers me, in any case and in regards to the Wifi hotspot, what about after installing a ROM, does it stay locked or the app becomes the standard manager for the Wifi hotspot?, I wish I could rewrite the app on the stock ROM but I don't really know how to get into that...

My SGS2x works fine with Mobilicity, been using it with them since the 30th.
wifi tethering worked from day 1 using the stock telus install. I'm now using several custom ROMs, and overall I'm really happy with the phone on mobilicity. their 3g internet leaves lots to be desired though, perhaps it will improve, but it is an unlimited carrier.

He was asking for a non-root solution.....Glad there's another way out there using root. But I think if you root the phone, you mind as well throw another ROM on there. Removes all the bloatware as well.

There's a stripped down version of the stock ROM. Never tried it but maybe that will work. You should just use one of those custom roms if you're going to root it. They have tweaks and other whatnots that improve your phone's performance. Once you go custom, you don't want to go back to stock.

Agreed, it's been brutal. Hopefully they can get a few more cell towers up.

The issue isn't cell towers, the issue is back end internet, after the IP transmission gets through their cell network to whatever centre they use, the internet connection to that that all of Toronto shares it ****ty and can't keep up. It's not a single overloaded tower that's the issue, as you can see by doing constant speed tests while roaming around.
Backend internet connections are expensive, especially the bandwidth on them. Small carrier can't afford to keep up to it's unlimited bandwidth demands.

Well, this is not rooted yet so that's a huge difference since ur phone will for sure include modifications to the radio, in all (I just figured it) is about Samsung, I have a N8 and a NS, compared the 2 with the SMGS2 (T989) and there is a thing in common between the NS and the T989, getting signal from cold boot or out of dead spots is a pain, my N8 picks the signal almost immediately, on the NS running stock it takes a good 2 to 3 mins (or more if out of cold boot) to get signal but the NS running MIUI makes things faster, I presume and since the stock SMGS2 takes a long time (like the NS) the same will happen when u run the phone with a modded ROM, it will pick signal faster.
So I guess it's all about rooting

I agree with the backend connection. But I think it's a bit of both. Some areas don't have as many cell towers as others. (in my area, i only have two) So I have a feeling it's both rather than just the backend.
Hopefully, they have a good new subs-to-upgrade interval so the speeds will get better.
well, regarding the nexus S
a lot of people in WIND also complains that it always stays in "emergency mode calls only, blah blah blah" basically unable to attach itself to the network.
i seldomly get that on my Nexus S, but that's probably because it's customized
but on the T989, i don't have that problem even in stock
so that's actually very nice

That reinforce my statement, is not really the network but mostly the way Samsung works the radios on their phones on the 1700 Mhz freq or at least for us, don't know in the US.
My NS running stock is a pain, modded works nicely, takes a bit longer than my Nokia but gets the network faster than running stock Android, I bet the same happens with the T989.
I am currently on Mobilicity in Vancouver with a crappy cheap phone and it has a hell of a time getting reception on the network. I live in East Van near victoria and I get reception in only 1 room in my place. I am planning on getting the Telus GS2X in a couple of weeks. Would this help my problem? Can anyone who lives in Vancouver and has the GS2X comment on his/her reception in east van?
Thanks alot.

a new phone might not help if the tower is physically too far from your location
however a good phone with good reception could improve your problem
the only way to find out is to try the phone in your house and see if it works for you
Does anyone know the best place to buy this phone and have it shipped to usa. I know tmobile sells the phone but if I use a tmobile branded android phone they up the cost of my service.
If u want the phone not branded to T-Mo then u'll have to get the Telus version sine it comes with no T-Mo stuff, I don't know of this model to be able factory unlocked
On the other hand I have a couple of new questions:
1> Is there a way to fix/access the MMS?, on Mobi I'm getting errors when receiving MMS, the pixs come all blurry.
2> Any way to enable the Wifi Tethering?, using the T-Mo model is just impossible unless u have the T-Mo sim which is not the case and I haven't seen any of the existing ROM's addressing the issue (sorry if I missed the part, so pls let me know if it's fixed )
Thx
1) check the apn settings and match it to the mobilicity ones. Head over to hofo and there's a thread about it
2) you need to root your phone &, put a custom rom on it. There's another way of disabling a process but I suggest the former

HTC one x & some serious data speed problems

Hi,
I have looked everywhere for a solution with no luck
I just bought a htc one x from Singapore unlocked and unbranded, i live in Australia and i am having really slow data speeds on telstra next g.
Phone calls and txts are great, but speed tests are terrible! My latest results are
DL: 0.28kps UL 0.38kps to my nearest server.
So im just asking if there is any hope to rectify this problem like a different radio or rom, anything really.?
thanks guys
What is your WiFi speed like?
Sent from my HTC One X using xda premium
Have you checked your APN settings?
my wifi speed is super fast, as fast as my desktop speeds,
i have set my apn settings to the recommended telstra settings an everything works just data is slow.
i spoke to HTC and they said that the IMEI number was suited to India, and that there was no way to fix this. I even mentioned flashing the radio and he said it was hardware specific so software couldn't change it.
Is he lying??
Here is a helpful link for telstra phones. I know your phone isnt 4G but it cant help to have a look at the article.
It says to change your APN to telstra.internet.
Have a look at your to see if it says telstra.datapack
http://www.lifehacker.com.au/2012/05/how-to-get-an-overseas-4g-phone-working-on-telstras-4g-network/
(Most recent result) I'm gettting 9.97Mbps down and 1.01Mbps upload over Telstra Next G in Melbourne. Fastest 3G mobile I've ever seen.
Your area is either very congested or your antenna on the inside of the phone is loose. Try testing around midnight when things are quiet and let us know...

Thanks for your results proves that it is possible to have this hand set working on Telstra with blazing speeds,
I have tested at all hours of the day and its speed are consistently slow. last night at 11pm i tested it and got the exact thing i got at 4pm earlier that day.
My apn settings are exactly what it should be, is my baseband firmware different to you guys or anything? i am on 1.1204.103.14.
i tested my phone at midnight and the fastest i got was 0.79 dl and 0.91 upload.
i have ordered a new one x from mobi city and im returning the one from ebay due to some screen defects as well.

I hope that resolved it for you. I will note that I have been 'Speed Testing' Telstra for a couple of years now, and sometimes I do see results that are as bad as yours. My most recent test on my HOX got me results that bad! But mostly mine are very good. If you are consistently getting results that bad then I would suggest your handset may be faulty.
p.s. Try flashing a custom ROM that allows you to disable 'Fast Dormancy'. LeeDroid and Team Pkmn are two that come to mind.
p.p.s. I also found that using any AOSP ROM's such as Trip's CM9, that data speeds were terrible, consistently. The only ones I can get good speed with are HTC (custom and stock) ROM's. In fact I think better to be custom with regards to my point above about Fast Dormancy.
thanks for advise guys.
In the end i sent back the phone and ordered a replacement which works great! no defects yay. network speed is around 5-8mbdl and 500kps-3mb ul.
so it was just a dud phone that was holding me back.
now its time to flash some roms!
im having data speed problems on att. im getting like .3 down and like 1 up. i got the apn settings off android police. im running cleanrom 3.1 standard. yes i have the one x i just havnt changed my signature

Most AT&T data speed issues are from the plan provisioned in your account not being mapped correctly to the SIM and/or APN's you're using. If you're on a MEdia Net or data for Non-Smartphones plan you need to use the Cingular APN. If you're on a 4G plan you need to use the "Phone" APN. You can do a search on XDA to find the respective settings. Some people in the SGS3 forum that were on the prepaid $50 unlimited plan had their data shut off a couple of days ago. If you're on that plan look up the thread on the international SGS3 forum. It's not the phone because I'm on the data for Non-Smartphones plan and am getting better data speeds than I did with my i9100. I didn't have to touch the settings. I popped the SIM in, the phone read the settings, and I was good to go.

[Q] Data service iffy on LTE - phone or Straight Talk issue

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.

the funny part is that Google.com always works, whatsapp works, googleplay works. so it seems a problem with throttling or filtering to me.

yes. completely incompetent. asked for a supervisor; no way to speak to one.
I posted on Twitter and ST got back to me asking to send them an email. I did. 10 different people sending me emails with conflicting actions.
insanely frustrating.

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.

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

N920I - Weak 4G. Can no longer make or recieve calls. Possibly a local 3G tower was turned off.

My Galaxy Note 5 SM-N920I purchased December of 2015 can no longer make or receieve calls. My provider is TracFone via the Bring Your Own Phone program. I use their SIM card and it has worked all this time. Until recently the phones features have stopped working. I think they have been disabling the 3G in my area, as everyone is converting to 4G now.
Note 5 is supposed to support 4G but it's definitely been having issues. Text and internet still works. however texts are sometimes delayed on occasion, not always, usually it's fine. Data speed just now was tested at 10 mbps down, 3 mbps up. Signal bars are consistently low, regardless of physical location; inside, outside, other side of town, SIM status shows signal always between -108dBm and -118dBm. This is likely why I cannot make or receive calls, but the question is, why is this happening?
Like I said, I suspect they are shutting down 3G in this area, so the best theory I've been able to come up with is this: perhaps 4G has always sucked on this phone but I never noticed because it would fall back to the good 3G connection. Now that 3G is gone in this area, all I have to use is 4G which is a shoddy connection.
Further research has found in the early days of this phone there were numerous reports of weak/no signal. See these threads:
Fed Up With Terrible Reception
Hey all, I'm kind of venting here and at the same time hoping for some sort of direction because I'm absolutely fed up with my S6. I upgraded roughly a month and a half ago from an S4. My phone usage was below normal for the first week or two as I was busy with a variety of projects. As my...

No signal/network on my note 5
Hi everyone, so I just got this note 5 N920P last two weeks but I noticed its OS was lollipop...waited for updates for 7.0 but nothing so I went ahead and downloaded Odin with latest firmware from samobile and did it my self, now here the problems start to show first of all this hands free...
forums.androidcentral.com
One theory was that the 4G antenna they used in the Note 5 / S6 was of poor design. Causing weak signal.
Things I have tried and did not work:
-Contacted TracFone. They confirmed the device is supported and provisioned correctly. They recommended a new SIM card.
-Replaced the SIM card with a brand new one
-Factory reset the device. It's running the stock Android 7.0 Nougat which was the last up to date version available.
-Tinkered with various service menus including *#2263# and *#0011#. Messing about with the LTE band settings didn't change the signal strength ever. Regardless of the LTE band, it stays in that -108 to -118 range, too weak for calling.
What can be done to fix this? Possible ideas:
-Internal antenna replacement, but this seems either expensive to have someone do, or extremely difficult to do oneself. Would it even make a difference? Has anyone tried this?
-Software. Could the issue have been introduced during one of the software updates? Planned obsolescence perhaps? Could we revert to an earlier firmware to potentially resolve this? has anyone tried this?
-Firmware. Could we upgrade the firmware to a later, unsupported version safely? Perhaps the issue was fixd in later Android versions but has not been adressed in older devices that are no longer updated.
I'm the kind of person who likes to use my things until they absolutely die. This Note 5 has been perfectly fine until recently. There is nothing wrong with it. It's still modern, fast, and has a great camera. I would HATE to have to replace a phone for such a stupid reason. Not only is money tight, but it's such a waste when this thing is still perfect apart from this weak 4G signal.
Has anyone else had this issue? Have you resolved it? Any help appreciated. Thank you.
Try a network reset.
Clear sim toolkit data.
Clear system cache.
The access point profile may need updating or maybe the sim?
