T-mobile network location and 4g being very strange - T-Mobile, Samsung Galaxy SIII

I have a galaxy s 3 t999 rooted running on carbon room 4.2. My phone does this strange thing with 4g and data location though... I run various speed tests and I get 200-400kbps in an area where I have full bars of hspa+ and used to get 13mbps. (the tower is about 500 feet behind where I'm at most of my day). Also when I run these speed tests, my ping is sometimes over 200 and I get a crazy location like Kansas City or new York, but I'm sitting here in Memphis Tennessee, even with location settings turned on. If anyone can send me some insight it would be greatly appreciated. If I have to flash a new radio then so be it. Here is an attached screen shot

I bet its the ROM your using. I tend to get different signals whenever I switch between ROM's as I do usually. If you haven't solved the problem already, try switching ROM's.

Or start by flashing back to stock. Then test and if things are ok, then try flashing some roms. This may be an issue with how close you are to the tower. 500 ft is probably not far enough away to be in line of sight and its signal may be overshooting you. It could receive your signal, but you may not receive its in return. Go about a 1/4 mile away, turn airplane mode on then off and see how it functions then.
Also, call T-Mobile to see if any towers in your area are experiencing problems or are under maintenance.
If that doesn't help, id try different modems as well. Could be due to the upgrade to LTE perhaps.

happen to me too, sometime speed drop to ~0.50Mb, tried different ROM and still same thing, only fix is turn On and Off air plane mode, hey i'm work in memphis, TN and live in Bartlett, TN

Love my Memphis lol. Born and raised here. Thanks for the tip, if it narrows it down at all I live in Germantown and the tower is on a TVA line but it's in eyesight. Only a tree or 2 blocks it. Thanks for the feedback though. I've called tmo many times and they reset my connection which I could do by doing a battery pull, but whatever. Thanks for the replies guys

Does it seem to go quick enough for regular use?
In speedtest, your latency (ping) will always be high. While idle the phone will drop to 2g/3g to save power and bandwidth. It has to switch over when you start using it which accounts for your ping times.
I dont understand how it picks its server either. But you can manually select it if you choose. Read through my modem thread too btw. I should have some other speed test sites listed should you choose to try a different one. Comcast has a speed test page is an example.
Sent from my SGH-T999 using xda premium

This also happens to me I'm in myrtle beach sc and if I do speed test, it will say my server is in Tenn or KS. Have had network reset menu times still does it. But I have great speeds none the less so in my opinion I say let it ride unless it is affecting your speeds. Again my opinion I'm no pro

I should also mention that just because a server is closest, doesn't mean its the fastest or best choice. I do know it tries to automatically pick the best one, but im not sure how exactly it does this. I imagine the app attempts to pick a server by examining things like network congestion, response time, maybe the number of hops it makes, etc. Just speculation. (And it probably receives this info from its own server, so its not actually doing all this from your phone)
in the past Ive gotten blazing fast speeds from a server 250 mi away and quite slow speeds from ones only 40-100 mi away.
Unless your actual usability is suffering, I think youre probabky ok.
Sent from my SGH-T999 using xda premium

Thanks for the reply. I'll check your thread out. The speeds are five one I restart the phone but its an extreme annoyance getting 200kbps

[Q] Limited to no 4G connection

I searched but on the whole it seems that the people experiencing the same issues don't have custom roms on their phones.
I essentially have no data connection whatsoever and like many others I went from having ~90 ping, 9-10Mbps down, and 1-3Mpbs up to having 1000+ ping and .05Mbps up/down.
I'm currently on the CM10 - 9/20 nightly (and I was on the 9/05 nightly) with lean kernel .15 and I've tried UVDLI8, UVDLI7, UVDLI6 and UVALEM basebands and nothing seems to help. As far as I can tell my IMEI is intact and I can make calls out, receive texts, etc... except anything relating to data is ridiculously slow. My brother seems to get fairly decent speeds and he is rooted and has a custom rom on his G2x. Is it possible that they're throttling only my line?
I've tried talking with T-Mobile and their customer service reps tell me things like "hold down the power button until your phone shuts off" so... not very helpful. Any suggestions or recommendations would be very much appreciated.
So I worked with the T-mobile CSR rep and they told me to change some of the settings in the APN, and now I don't get any signal, do any of you guys have what the APN settings were for CM10?
CM10 doesn't have specific APN settings. You can Google T-Mobile APN settings and use those.
Where are you located?

Yeah definitely spotty. So I was driving around Houston yesterday and was doing speedtests as I was going, turns out I have absolutely fantastic data speeds until I take the exit off the highway and head towards my house (signal gets progressively worse the closer I get to my house). It's literally like a dead spot sitting right around my house which is only 5 min from the highway and 15+ Mbps download speeds. I called T-Mobile and they claim that there aren't any towers down and that I'm not being throttled but I used to be able to get fairly decent speeds at my house. At least now I know it's not my phone and it's not the rom/kernel/modem.
Are there hills?? Signal will always be stronger near highways because that's where the towers are.
Download the app Phone Info and try to force 4G?
I'm less than 5 minutes from the highway and no, there aren't any hills. I did hear back from T-mobile and now they're finally admitting there might be an issue with one of the towers in my area.
I had the same exact issue. It was a tower problem and it took about 3 weeks to resolve. I was compensated by having my data credited for a month. $30 total. It's really frustrating I know but it should pass in time.
Yeah so it was a tower issue for sure. I'm back to getting ~10-15 down at home. Glad that was finally resolved.

[Q] Please help having problems with GS3 4G/3G anytype of data other than WiFi.

My Phone is being so SLOW on "4G" Its downloading according to the Speedtest app at .30 mb/s but if i go to www.mobilespeedtest.com and do the 7mb test it shows 9650 kb/s then on www.speedof.me it shows 40-55mb/s I have no idea what the heck is going on. I do knw that facebook/playstore apps and such download super slow. I had customer service try to help me they couldn't figure it out so they forwarded it to a tech. If anyone could help me it would be cool. I even updated to the Newest Modem. *shrugs* Maybe cause of "Sandy" their service is slow. Yano?
If you are in the N.E. then yes, the storm is apparently causing problems even for those who weren't hit that hard.
The speedtest app is not a good real world use indicator. Could be the server your using.
If you're getting 9mb down for some sites, and faster/slower on others, well, that's the net!
You say that facebook app is slow. What about going straight to the site?
If your speeds are jumibg around as much as you're implying, where sometimes its fast, sometimes its slow, then id say its probably due to the storm if you're in that area. Give it a few days and see.

It won't go to 4g? Earlier you said it was just slow on 4g. If you're stuck on edge check that your imei isn't zero. If it is you need to visit peoplearmys and geeks threads. Check the stickies.

Sorry its taken so long to reply I've tried all the above. IMEI isn't 0000 or anything. Flashed the newest radios then tried others. Not sure what is going on. It shows "3G" in the top status bar; go under mobile settings it shows UMTS:3 for data connection. This is both my phone and my Fiance's and she has the Galaxy Blaze. Our area is covered under 4G that is for sure; and we have the TRULY unlimited 4G data for 30$ a month.

If both of your phones are having the same problem and they are different phones, then I'm almost completely certain that the problem is not the phone.
Its a tmobile network/tower problem.
If you go to a different area of town do you get 4g?
Call tmobile to report it and make sure to tell them its happening on two different phones and if they are on separate or same accounts. Whether or not you can get 4g elsewhere will help them too.

No sadly my town is one of the few around here if u wanna check the coverage map and see maybe give suggestion it's Angola IN. I called them and they said take your batteries oit and turn the phones off for 5 mins they are resetting the network. Did that and its the same thing shows UMTS:3. I'll call them and suggest what u said then.

Werid 4g speeds, need help ruling out phone or network

I bought a Tmobile Galaxy S3 on new years from staples, and since ive got the phone ive been experiencing strange 4g speeds. While im in my house, I always have full signal strength, and it always says 4G. I live in the Bronx in New York City, and when the 4g is working properly, I get upwards of 20 megabits down, and 1-2 up. Now I could literally be sitting in the exact same spot, and later ill test the phone and it says 0.2 - 0.3 megabits, and like over 1000 ping and the up is so slow it doesnt even measure it. It usually comes back after waiting, turning airplane mode off and on multiple times or doing a battery pull. I find it strange that I can get either 21 mbps or 0.3 in the same house, while always having full bars. In the phone status sometimes it would say UTMS or HSPA, so it does switch from 3g to 4g sometimes. The thing is my previous phone was Nexus S with 3g and im pretty sure I never had a problem loading a simple image in my house because the internet was so slow. I consistently pulled 3-6 mbps on that phone. I tried calling t-mobile 3 times and they give me the same basic crap, like clear your cache, make sure airplane mode is off (really?) make sure youre network mode is on auto (i tried auto and wcdma only and it still gets slow) and all that other stuff. Is there anything else I could try to see if its a network or phone issue?
It sounds like it might be something with your local tower. I would call Tmobile and put in a repair ticket.

Thanks, I just did that. Called t-mobile and just directly asked them to check for tower issues, and they filed a complaint. They said to check back in 3 days, hopefully this gets fixed, or else it might be the phone. Do you think flashing different modems would change anything?

It wouldn't hurt to try. What are you currently running? (rom/kernel/modem)
Sent from my SGH-T999 using Tapatalk 2
Completely stock 4.1.1, with UVDLJA modem, which is the latest I believe. The phone is relatively new so I wanted to try touchwiz before I rooted. Does installing something like cm10 change the modem? Or is it independent of rom/kernel. I saw an application for tmo that can change between multiple modems pretty quickly, I might give it a try.

I work for T-Mo,
If I may lend my opinion,
To me, it definitely sounds like the tower. If you go from 20Mbit down to 0.2, and with 1000ms latency, it's super obvious there is something
wrong with the tower, or there is significant demand on the tower from other users, hey its NYC population density is insane.
Something to note as well, New York City is "in progress" for "network modernization" where they are switching to 1900Mhz.
This is why some people who have iPhones are now getting 3G in certain areas, unlocked devices, as well as AT&T phones can have 3G down there.
Due to this, since there is quite a lot of switching around going on down there, that's probably what's going on.
Example:
http://www.tmonews.com/2013/01/t-mobiles-network-modernization-what-is-it-where-can-i-get-coverage/
Hope it helps.
I see, well that makes sense. I dont really mind if its a tower issue because thatll be fixed eventually, I just would of hated if I had to replace the phone, it would of been such a hassle because I didnt buy it direct from t-mo. Thanks to both of you!
Also, since t-mobile seems to be using multiple bands for 4g, I guess it would be better to leave it on auto in network settings?

If it helps you at all to see if you are on a different band than 1700/2100mhz
You can go into the dialer and do:
*#0011#
Up top mine says band 4
Which is for 1700mhz AWS
BAND 2
which is for 1900mhz PCS.
You might be on band 4 or 2 on a tower by tower basis, or if they are making adjustments
You might be switched but that is above my pay grade lol

Anyone notice their service getting worse?

At first I thought it might have been my rom, but it seems it's happening with my GF's note 2 also.
Coverage we used to receive in some areas is almost completely gone. It will show signal and the 4g symbol but basically have NO internet service whatsoever.
On a better note, we've been receiving coverage in some areas we don't usually have it.
I'm hoping this is just a temporary thing due to the attempts to upgrade towers for LTE.
I don't know if it's because of the UVBMB4 update, but t-mobile service has been pretty crappy lately. Period.
We're in the San Gabriel Valley area.
Link for older UVALL4 modem below, people seem to experience better service

I believe my service has suffered as well. Before the last update that enabled our Lte radios, I had great speeds, now it's slowed Way down. I'm in San Diego CA. Hope that it's just as the Op said, LTE towers being updated and what not.

Definitely have noticed a deterioration of service over the past month here in NYC.
Its because for some reason that new LTE APN is slow on HSPA+.. unless you have LTE in your area switch to the EPC APN. You can find the settings online. Its litter ally consistently a difference of 6+ mbps I have extensively speed tested lol..... click thanks if this helped

YES! My service has sucked royally for the past month or so. Data latency/hangups/slowness, and the signal will just completely go away sometimes. I noticed that it started as soon as I flashed the most recent radio too, I'm about to go back to the old one.
Count me in, even my regular phone reception went from 4 bars no 1 or 0!
Can anyone point to towards old radio to flash? I go from no signal downstairs to full bars upstairs...theres an obv issue with new radio.
Yup I've noticed this beginning this week I've made zero changes to the phone. I used to get full bars at work and this week it bounces between full and 1 bar regularly. Theure messing with towers for sure

However... in my corner big red has same problems as they wanted to not have tons of towers in this corner and theres only a ATT Tower....for a decent distance. basically reception fringe. though I am a new subscriber so i haven't experienced normal TMO, I literally got my device yesterday around 6pmish but it def wasn't normal and flashing previous radio did fix it like it solved everyone elses issue

my problems started last friday. i have limited to no service at all; no data, no voice, even no signal at times (circle with line through it, not just no bars). when i do get a signal, the phone refuses to register on the network. when im at home, i have intermittent service. i miss calls, texts wont send, if i do get a working call, it drops after a bit. there are times when it works fine, even on LTE but it never last long. went to the tmo store last night and they gave me a new sim which didnt do squat. already done the factory reset option (twice). phone has never been rooted, all stock. im in the KC metro so not like in the middle of nowhere. they said my next step is a warranty replacement phone if the sim didnt help. not sure if my problem is at all related to everyone elses in this thread, but yeah, service has sucked.
One of the issues, especially if you switch from 4g to edge to gprs a lot, is a setting in the new modem.
It's something called acquisition order. It has 3 settings:automatic, gsm_umts, umts_gsm. In short it tells the phone what kind of network to prefer. It will search for and use that type of network first.
Prior to the latest update it was set to auto. Now it is set to prefer umts. For some reason this has caused an issue I've come to call phantom 4g. Where it'll say 4g with no bars and no data service.
That is my guess. I'll look into it further.

Thanks guys for the heads up on switching to an older radio, I dont have LTE in Miami yet and was having slow internet for the last 3 weeks, I just switched and wow! What a difference. I'm also using the Epic APN.
I also noticed that speeds were degraded after the update. However, there is a simply fix to make your web a tad bit faster....
Go into your network settings, and switch your mobile network from LTE/4g/3g/2g to just 4G/3g/2g
your device will stop looking for an LTE connection and will just utilize HSPA+
Made a world of a difference on my own device. Connecting to the play store, opening web pages, everything was right back to where it was before the update.
Obviously if you live in an LTE area, there is no need to do this...

Hastily spouted for your befuddlement

T-Mobile data unreliable signal.

Is anyone having a data problem with their network? I'm in the Everett Washington area and I've been having a terrible time with data! I go from 4 bars to no bars a split second. When I do get bars none of the apps seem to work from lack of connectivity. I use to get up to 20mbps when I did a speed test now I barely get between 6-8mbps. I'm really thinking about changing carriers. Its getting pretty ridiculous! I pay for unlimited data without being able to use the service half the time.

It seemed to me that T-Mobile, even though they call it "unlimited" cut you back after so much usage. Sure you still get data but not full speeds whether yours is 4g or 3g. They cut the speeds down. It was like clockwork every month.
There was many things I didn't like about T-Mobile that being number two. Number one was lack of coverage, anytime I was out of town, I wouldn't have hardly ANY service.

I hadn't tried it for a while because I've been using WiFi when I'm home because of the horrible speeds, and I just went back to the exact spot and got 6-10mbps from 4 straight speedtests, then I moved the phone a few feet away and I got 1.02mbps lol

Man that's just horrible!!! But at least you can get the speed test going. I can't even get the data going even if I have full bars!! Lmao

Is anyone having a data problem with their network? I'm in the Everett Washington area and I've been having a terrible time with data! I go from 4 bars to no bars a split second. When I do get bars none of the apps seem to work from lack of connectivity. I use to get up to 20mbps when I did a speed test now I barely get between 6-8mbps. I'm really thinking about changing carriers. Its getting pretty ridiculous! I pay for unlimited data without being able to use the service half the time.
Any of you experiencing this problem?

Try updating the modem first. Or downgrading it. Also your phone could have started to go bad. Does it happen everywhere
tmobile s3 running wicked. I still use a t9 text app so excuse the errors
I was actually running on UVDLJA then upgraded to the UVDMD5 package which had the bootloader, firmware and modem. The only thing I noticed was better battery life but only about an hour difference other than that it pretty much seems equal to UVDLJA. I noticed that there is a newer version of the package so in going to try flashing the new one and see if it will perhaps make any changes.

@all
Try not to be too quick to bash on T-Mobile for poor speeds. They are refarming the AWS and PCS bands and rolling out LTE all over the place.
This is a nationwide project so it is reasonable to expect some issues.
Suggestions:
Call support to ask about any outages or upgrading in your area.
Try out the different modems and tweaks in my thread.
Give it a week. (Shouldnt take that long if they're upgrading, but just to be fair)
If you still see no improvement start writing/emailing/calling and posting on the T-Mobile support forums. If this many people are having problems and they get bombarded about it, it may force some action. Be persistent if it comes to this point.
I really do think that given time, everything will go back to normal, and maybe even better.
Also, for those of you who ALWAYS use their mobile data, even when wifi is available, just switch to wifi please! It saves your battery and if there is any network congestion everyone will benefit.
One last thing. Once the network in your area has been upgraded, you may find that the modem that was the best for you before is no longer. Retest, and update the map in my radio thread so everyone can benefit.

The only change is the updater-script. There is no benefit to reflashing if you already have. You won't see any update to md5 till samsung releases it.

In light of LTE being unofficially turned on yesterday here in Denver, my 1700 band speeds cut in half. The fastest consistent speed I could get was about 6Mbps with the average being 3-4.
I locked my phone to 1900 WCDMA and guess what? Back to 11-12Mbps. Faster upload too, 2.3-2.5Mbps. My initial fears about moving HSPA to 1900 may have been completely wrong. That is probably why my phone prefers the 1900 band now and has for a few months.
Long story short, give it time, everything will stabilize when the network upgrades are complete.
Anyone that wants to experiment with speeds on the different bands, from the TouchWiz dialer (sorry this doesn't work on any ROM lacking TouchWiz), dial *#2263#, go to WCDMA band preference and change it to either 1700 or 1900. This will lock the phone to WCDMA only though so if you don't have a strong WCDMA signal in your area your calls can and will drop. If this is the case, just go back into the menu and set it to automatic. Generally the phone will continue to prefer whatever band it was locked on until you reboot your phone anyway but at least this way it can switch bands for call purposes.
Meant to post this here, but somehow put it in the wrong thread....
I think I may need to sleep at some point!!
Sorry for all the reading guys, but just a little more.
There have been several threads opened recently on this exact subject. Seek them out as you will find some other things to try. Some have worked for some people while not others, so ymmv.
This is a post from EtherealRemnant. You have to do this from the stock dialer, but give it a shot.
Start a big download and go to the dialer, input *#0011#. Take note of the band you are on (2 or 4) and which items have a 1 on them out of HSPA and HSDPA. If you are on band 2 and see a one next to either of those options, you can try forcing 1700 by using *#2263# and choosing it under WCDMA. This will cause you to lose service if you have poor 1700 coverage, particularly for voice calls but you can always set it back by going back to the main 2263 menu and hitting automatic.
If those don't work or you see zeroes have you gone into phone status to see if you have an IMEI? Because that will lock you to UMTS. Shortcut to find out - *#06#

This is from late last year, and I have had it posted in my baseband thread since.
Thought I'd post it here too for those who never make it to the 3rd post! It may help some people understand what T-Mobile is actually doing with their network upgrades.

I too, live in Everett WA, but a tad closer to Mill Creek. My map shows I am 75 meters from the closest tower, and Tmo keeps telling me that a tech has checked the tower's operation and found it to be working fine... I don't think their tech is as thorough as I would be. I envision some lazy turd driving near by and says... "yep it's working, and leaves, parking somewhere and chalking up a few hours of naptime and writing up a worksheet making it look like it was a completed job. I have wrestled with TMo for quite a while with the same problem you have. I have a repeater installed in the house on the third floor, and it hardly helps, but any small gain coupled with others have actually made my phone, at least, able to make calls! I have tweaked using a lot of different things, and have found this most beneficial.
Using stock rooted 4.1.1 OS (root66)
Baseband UVDLJC
and the 1900 freq.
My sig still jumps all over the place (like yours) but at least now, I hardly ever have NO SIGNAL.....
Believe me, I have got on Tmo's case like something fierce..... They finally offered to even cancel any charges for my contract termination, but that was not my point for complaining! I just wanted to be able to use the phone, and it wasn't possible at that time. Now, at least, the phone works, I can walk 100 ft to the street, and get full bars, 4G, so I know there is coverage, but indoors, it's not that good. The funny part is that all the main roads have GREAT 4G Coverage, and in our community, indoor reception is not the greatest, to say the least.
Bottom line, you are not the only TMo client that is having problems and hopefully, the Doc's right!
Let's hope that the reception gets back to being as good as it was, or maybe even better!
Good Luck, and Aloha!
