[Q] Why can't my GNex connect to T-Mobile 3G?

Hi everyone,
I'm reasonably certain that this isn't a redundant thread -- at least, none of the discussions I've read have helped me fix my problem. Anyway, here goes:
I have a new i9250T that I purchased through Amazon. When I got it, I popped in the SIM card from my Nexus One (both SIM and phone acquired in January 2010). Everything worked fine, EXCEPT that I could only connect to T-Mobile's 2G network (Network Type = Edge:2). After trying everything I could think of, I called T-Mobile, and the tech told me that my 2-year-old SIM card was 2G only and that I should update it. So I went to a T-Mobile store and got a new SIM. Alas, it doesn't seem to have worked.
I would REALLY appreciate any suggestions. Some additional info:
-- I'm in Philadelphia, in a very good coverage area.
-- I flashed yakju, 4.0.2, and UGLC1 radio before getting the new SIM.
Again, any thoughts will be appreciated. I've seen enough posts on various boards from people successfully using this phone on T-Mobile to not give up, but I'm out of ideas.

check what your APN settings are on your N1 and make sure that they ate the same on your GN.

Thanks. I'll check that tomorrow morning (I left the N1 at my office).

i too received my galaxy nexus today from amazon, i also only seem to be receiving EDGE service. The apn settings were enter automatically from the sim card i assume, and seem to be the same as my old Galaxy S 4g.What else can we try.

Weirdest crap... aren't the GNEX suppose to work with either GSM Carriers 3G? From what I read lol ...
- Google Galaxy Nexus

I get 3G/H with my Nexus. Running Android Revolution HD 3.0 w/ franco's kernel. Not sure if I got it before then running stock, though.

It should definitely work no question with little issue. Just pop in your sim and good to go. Maybe its some random network issue in your area that coincidentally started?

Same here, got it on Amazon. it's a GT-I9250T which means it's for the Australian market (I9250 International, I9250M Canada, I9250T Australia). I'm just stuck on EDGE, but works fine on AT&T - I tried it with my gf's sim card.
The problem is with the frequencies. T-mobile uses 1700 and 2100 (both! for upload and download), AT&T uses 1900Hz. The phone is supposed to be a pentaband phone that's able to work on all on the freqs besides others (850, 900). So my guess after a few days research is that it's limited in the software. Still researching the solution...
Let's keep each other posted on this, i'm eager to get my 4G back !!!

Information from another post: flashing UGLC1 radio helps. Good luck all

I had the same issues with no 3g speeds on any radios except a random docomo radio until today.
Based on a few posts in the baseband thread i tried the settings in the hidden menu
Go into the phone dialer and type
*#*#4636#*#* -This should bring up a testing menu
Go into phone info, then pull up the settings menu
There should be a select radio band button
Try the USA band, if that doesn't work, try automatic.
This worked for me, I've since flashed 4 different radios that hadn't worked previously and now do at standard speeds vs edge only.

Well my buddy bought his also from amazon and had the same issue as the OP. But luckily we got it fixed. I believe what he did was only tinker with the APN settings. Under APN Type in your T Mobile apn make sure the correct profiles are there. One of them could be data but I'm not sure as I'm on SIMPLE Mobile and my buddy is on T Mobile, sorry. If you get it working and your MMS isn't working, then add mms to the profile as well. That should do it. He did get his phone with 4.0.1 and I updated it to 4.0.4 Android Revolution 3.0 just like me as well but it wasn't until we tinkered with his settings did it work. Oh and we also swapped for a new SIM. Let me know if this helped guys. I'll try getting his settings if I see him tomorrow.
Edit: his was also an Australian galaxy nexus. But he seems be having everything working now

So ait this is the Australian version? They use 850 and 2100 bands so is it possible the other bands are disabled on that version?

Problem solved!
I took chimaki1's advice and fiddled with the radio band setting. I had done this previously, but I had always selected "USA Band." This time, I selected "Automatic." Closed out of the Testing menu, and -- bingo! The wonderful 'H' appeared and I was now getting real speed -- 7.9mbps down, 2.8 up. Not as good as some of the insane speeds I've seen posted by GN owners on T-Mobile, but a lot better than 100kbps down I had been getting. Also, I didn't mess with the APN settings at all.
To recap the solution for others having the same issue:
From the phone dialer, enter *#*#4636#*#*
Tap "Phone information"
Tap the Settings icon at the bottom right
Tap "Select radio band"
Select "Automatic"
Close out of the Testing menu (you can just hit the Home key)
I can't remember whether I had to soft reset or not; I don't think I did.
I hope this works for others. Thanks very much to everyone who posted.

This is weird. my galaxy is still not getting 3G/4G Service even after changing radio band in the hidden test menu.
Is your galaxy running the stock software, or are you running something different. if so, what rom are you running

It's running the yakju image and OS version 4.0.2. I flashed both using the WugFresh tool. The phone came with yakjuxw (I think) and 4.0.1.

Not "disabled" but more like they're set up to "prefer" the Australian bands.

I'm having the same issue on the I9250T I just got. Stuck on edge. I played around with the hidden menu settings, still no luck. I'm using a TMo SIM card from my previous phone which had 4G so I doubt that its a time/patience issue. Any help will be appreciated.

My phone has had "H"/4G access since day one, if I put it on US-Band I only get Edge. I put it on AUTOMATIC and it works fine, leave it on AUTOMATIC.

Today I tried a friend's ATT SIM and it worked fine with H/3G speeds. popped the TMo SIM back in and I'm back to EDGE. Wondering if there is something that needs to be done to the phone settings or, or I was hopping some one could tell me what needs to be done.. thanks

(NQ)Can't Get LTE on AOKP rom on Rogers 1747M

Hey All,
So, for some reason, I am unable to get LTE when i am flashed on the AOKP jellybean rom for the SGH-1747M (rogers)
I did everything that was stated in Task's Gerrit (Changed the connection for WCDMA to LTE/GSM auto), all that does is work for a while on H+, then disconnects.
I've changed my apn settings to the Rogers LTE settings, which just cuts off communication all together
Ive flashed Rogers Modems, still to no avail.
The thing that bothers me is that other sgh-1747M users claim to have been getting LTE on the AOKP jellybean rom.
My question is WHY AM I HAVING TROUBLE!!!??? I know the Rom was made for an At&T sgh1747, so people may say thats why its not working, but people with Canadian SG3's have been able to get LTE on the same ROM im having trouble getting it on.
If theres anything at all im missing, can someone please clarify exactly what im missing and what I should do to get it working.
I love the AOKP jellybean ROM, i keep going back to it, but the LTE not working just hurts my feelings (since I am paying for an LTE smartphone plan). PLEASE SOMEONE HELP!!!
PS: the first time I ever changed from WCDMA to LTE/GSM autom i got a 4G symbol for about 30 secs.....never seen it again! HELP!

i dont have a gerrit. so im unsure what you are talking about.
you need to add a canadian LTE apn and then do this...
Enter *#*#4636#*#* into the dialer
phone information
set preferred network type
change to LTE/GSM auto

I'm not really sure. Being as I don't have a Canadian model its not something I can test. But I'm sure some Canadian users will be posting here to help you out soon.

when i try to change the preferred network it will not let me change it to anything else but to lte/gsm (prl) (i have the AT&T version)

Thats interesting. Maybe its because you are actually using at&t network. It works when I put it on LTE/GSM, but all I get is 3G and H+

Check your IMEI in about phone/status. If its showing 0, there's a thread for that.
If you're getting 4G icon and your mobile network status says LTE and are getting LTE speeds, then its cosmetic issue. I had that problem before.
What I did was I flashed Kyan's ROM 1.3 cause its based off of Rogers firmware. Once I verified I had LTE icon on Kyan ROM, then flashed the stock/rooted ROM after.

Interesting. I will try that method and see what happens. Thanks for the info; will post back with results soon

Ok, so after going through the whole process stated above, i WAS able to get a 4G symbol come every now and then. But before the connection actually finalizes and goes through (before it turns blue on the aokp rom), it disconnects and goes back to WCDMA preferred. I added the rogers LTE apn, and using that apn with the LTE/GSM auto selected allowed the 4G to come, but it keeps disconnecting. It even sometimes changes back to other apns on the list by itself
Anyone know if theres a way to lock the preferred network and apn settings?

enter apn settings, then REBOOT phone. After that, enter *#*#4636#*#* into phone dialer and go change to LTE/CMDA/GSM. that worked for me, I just needed to reboot my phone for the apn settings to work

Mine works until I reboot. Then it changes back to WCDMA. I'm on Telus.

LTE on canadian i747M (Rogers)
I had similar issue with LTE after flashing to AOKP rom. The fix provided by AOKP (after every reboot, type in *#*#4636#*#* and flipping the network type from WCDMA to LTE_only, then flip to LTE/GSM auto(PRL) ) works. LTE will show up as 4G. I have the 2012-09-30 AOKP build installed.
Yesterday all of a sudden I could not get LTE anymore. Not sure what happened as the only thing I did was to activate a new account on Google. Anyway the 4G/ flipping did not work anymore. Reflashed the rom several times, still the same issue, my phone will not get LTE/4G.
This morning tried the following and voila it worked, thought I will share this:
Flip the network type to LTE Only, there is no connection, REBOOT the phone.
1. After reboot, flip the network type to LTE Only again, this time, the connection worked - what a surprise/thrill.
2. Flipped the network type to LTE/GSM auto (PRL), connection was ok and 4G came on and stayed on. Did several reboots and repeated 1 and 2 and LTE/4G was ok.
Hope this helps.

I don't recommend you to use task aokp rom! You won't get LTE real speed and Dev won't help you since you are not an at&t user! He couldn't care less about the rest so try liquid jelly bean which is a lot faster and better or milestone 4 and aristodemo! They have better support although they are tw rom but worthy anyways

Task compiles that ROM based on AOKP source, but AOKP officially doesn't support att. Although I didn't have problems getting lte on his ROM the fact that you have to set it every time you reboot is why I am using cm10 for now otherwise it's a good ROM!

I'm having the same issues on my rogers branded s3. No matter what I do I can get lte to even appear. My apn auto rolls back to the provided apn and if I delete that I have no data at all. Hopefully this does have an answer because the Rom is amazing

Alright I think I have it figured out. I added the rogers APN related all others and the only change I made was I removed the info under APN type where it said internet+MMS and left it blank. Saved the APN rebooted and I have lte now. I even rebooted my phone and each time it boots up its showing 4g without having to play with any settings

[Q] TMO GS4 Network Modes on AT&T Network

So I recently got a T-Mobile GS4 for use on AT&T. I have set up the APNs, etc. and everything seems to be working, except for one annoying thing:
The device seems to be reverting it's Network Mode to WCDMA preferred instead of LTE/GSM Auto. I have tried setting this in Settings as well as in the Testing mode menu and it will not stick.
This happens every time the phone is booted, as well as when a call is made. When the phone is booted, it takes a long time to connect to the network, and when it finally does it is set to WCDMA preferred. I can then change it manually to be LTE/GSM auto.
When I make a call, the network drops from LTE to H/H+ as expected. However, after the call is completed, the network connection drops entirely and reconnects a short time thereafter but on WCDMA preferred.
Has anyone else experienced this issue, or have any ideas? If it makes any difference, I am running the latest CM10.2 for jfltetmo, without any other modifications.
Thanks in advance!
EDIT: I should add that the IMEI on file with AT&T is indeed for an AT&T LTE phone.

What I would do to solve this problem is to first go into recovery and make a nandroid backup.
The problem you are having is due to the fact that you are running CM10.2 rom which perhaps
is not 100% compatible with your specific phone and or carrier.
What you need to do is to flash an AT&T custom rom OR better yet flash Darthstalker's
AROMA Multi-Carrier rom and select AT&T after the rom starts flashing.
That way it will not only flash a proper AT&T rom but it will also flash the
proper kernel which you need if you want to use it on AT&T as well as
setting it up with the correct APN's which will stick.
The Darthstalker rom can be found here: http://forum.xda-developers.com/showthread.php?t=2292054
This rom has a lot of extra features, settings and options making it one of the best roms around
especially for someone like you who wants to use a tmobile phone on the AT&T network.
Give it a try, I am certain it would perform really well for you without any issues.
Good luck!

Thanks for the info. Looks like that is a TouchWiz ROM though... I'm looking for an AOSP one... Will look more

On second thought it would be a good idea to try this to see if the problem is eliminated. In the meantime, do you know of any AOSP ROMs that might have the same type of solution?

I've had my T-Mobile GS4 on ATT for a few months now and have had no problem with LTE after they had my phone's IMEI, and I was using the correct APN. This is the case on many TW and AOSP ROMs that I've tried. Good luck!

same here i have an m919 rooted stock mdl rom on at&T and have no such issue mine stays on lte.. both with phone or pta ap.. Have you tried reflashing and factory reset before setting stuff up...

Thanks to everybody for the info. I finally got it working:
I first backed up to the Touchwiz ROM mentioned and made sure data was working. Here I had to manually add the APN and then the settings stuck after reboot, calls, etc.
Then, I reinstalled CM 10.2 for jfltetmo. Magically, the setting is now sticky.
Thinking about it, I got the phone, unlocked it, and immediately installed CM without attempting to use the ATT sim card at all. Perhaps TW does something to make this stick, but I have no idea.

[Q] Stuck in 3G, have to switch to 4G manually... why?

Hello,
Recently my HTC One's antenna began acting strange. I flashed LiquidSmooth 3.0 beta with the provided Nuk3K3rn3l for m7spr. My phone was stuck in roaming and after calling *226, my phone apparently successfully activated itself to Verizon.
I've since reflashed back to a stock ROM/kernel, and while my 4G connectivity works fine, it will default to 3G any time it gets the chance and won't automatically switch back. I have to go into my settings, switch the GSM mode, and then switch back to CDMA/LTE (PRL) and 4G works perfectly. It will do this no matter what ROM/kernel I'm running.
Do I need a new RUIM? Do I need to reset my PRL and if so, how? Or am I just ****ed?

Go get a new Sim card to fix the issue.

You're asking a out a problem on an m7spr in a Forum devoted to the m7vzw???

Wrong forum, but look into updating your firmware.

The phone is an m7vzw, the kernel provided in the thread was an (allegedly) modified m7spr kernel. Thanks for the responses, that was what I figured... $11 mistake I suppose lol

New sim freind had same issue
A new sim card will fix this issue hoped this helped.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.

at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.

Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything

Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..
Thanks for your help mate. Can't believe I forgot to press the thanks button [emoji2]

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

Are you in a position to be able to return the device? Just in case

Thanks for the help mate.
I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Good luck fella, hope it all works out for you. With it being bought in the states would the band frequency of the device make a difference? Just spitballing there. Good luck..

Yes it would. He probably bought a cdma and has to have the correct bandwidths unlocked.
