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 !!!
NEW DEVELOPMENT!!!
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
Bought my phone form Rogers. LTE was working fine.
Was going to USA and paid an online company to send me unlock code.
Used it and went using Tmobile which only has EDGE data.
Just got back swapped back in my SIM From fRogers and can only get EDGE speeds.
Tried reboots rmoving SIM card.
Also made sure settigns were correct for Rogers APNs and also that toggle was on for GPS/HSPA/LTE.
To no avail.
Briefly, I toggled on and off the apn setting from ROgers LTE to tethering LTE and low and behold it seemed to work.
But now it is back to stuck on EDGE and nothibg I am doing can help.
Can this be a byproduct of the unlock?
Is my LTE faulty?
I s there some hidden menu where perhaps a setting can be changed for a fix?
I am depserate as the alternative is to return the phone and they are on backorder everywhere now.
There is no lte on tmobile yet. Second the tmobile note 2 has dormant radios that will only activate the lte capability by software update.
Im going to research your problem a little more ill send you a pm as to why it isnt going back to lte functionality if I find out something first...

I have a Canadian note 2 that had working LTE.I had it unlocked via a code emailed to me then next used it on tmobile at edge speeds.
Since returning home i cant get back onto data speeds above edge despite reboots.Simcard/battery pulls.
I ensured my network and apn were correct and that in setting under mobile the toggelchoice for auto including gsm//hspa/LTE was selected.
Are there perhaps some deeper settings via dialer code than might be able to turn back on the hspa/lte radios?
I've been using an S4 for about 2 weeks now, no problem. Last night I realized a text I sent never went through, and today my lock screen says "No Service" or "Searching" (despite the device showing full signal). I can't send/receive calls or texts, and I don't use a data connection. This SIM is also new (~2 weeks), and the device is neither rooted nor running a custom ROM. I've tried everything I could think of, like:
reboot
pull battery and SIM
confirmed APN settings on t-mobile site
tried alternate, non-"LTE" APN (epc tmobile com)
tried every network mode setting (GSM, GSM/WCDMA, etc.)
reset APN to default
turned on mobile data connection
manually scanned for networks (wouldn't connect to AT&T or T-mo)
select network automatically (wouldn't connect)
complete factory reset
I tried my SIM in another T-mo phone and it works; tried a different SIM in my S4 and it doesn't work. All other T-mo phones in my household are working fine. My S4 is definitely the problem here, but I don't see how the radio would just stop working after 2 weeks.
Has anyone else experienced/seen this? I never have, and it's driving me up a wall. I'm going to try my local T-mo store tomorrow, but I was hoping to fix it before then. Any help is greatly appreciated.
EDIT: I purchased the phone new on ebay. For a minute I thought the seller might have reported the phone stolen, but I checked the IMEI and it's clean.
Ive experience this but my service came back in about 25 minutes I did reset reboot battery pull sim pull it just came back on its own
Unrooted Samsung Galaxy S4 Up and Running
Rooted Mytouch 4G Slide retired
Rooted T-Mobile Sidekick Touch Obliterated
Rooted Mytouch 3G Slide Lost
Rooted T-Mobile G1 Dead
So I finally got to T-mobile today. Unfortunately, my hunch was right: the IMEI is blacklisted. Their in-house system must be more up to date than their web IMEI checker.
Time to solve this issue elsewhere.
Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).
*bump*
Any ideas?

I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.
I am having an issue with a phone I recently bought on eBay to replace my wife’s phone – a Samsung S3. After researching, I selected one that appeared to be compatible to our carriers’ network – AT&T. It’s a new factory unlocked LG G4 model US991 running Android 6.0 that arrived in a sealed LG box. I moved the sim card from the old phone to the new one, but I initially couldn’t get it to connect to our network. A call to AT&T customer service didn’t provide much help although they had me check the usual things when transferring a sim to a new phone. They advised to go to my AT&T store for help in getting it to connect. They were also unsuccessful after checking and verifying several things (not really sure what). They concluded that the phone must not really be unlocked as it was advertised.
Frustrated with that, I decided to try contacting the eBay seller about the issue and was happy to get a fairly quick reply, telling me to change the following network settings:
Select Mobile networks
Network mode – GSM/UMTS
GSM/UMTS settings
Network submode – Legacy 3GPP multi
Network operators – after choosing Search – found AT&T, RAT:WCDMA
And it worked - voice and texting both functioning well – and most importantly my wife was now happy. But it didn’t take long to realize the reception wasn’t nearly as good as my old Samsung S2 on the same network. We were in a rural location recently and where my phone was showing a decent signal, the G4 barely showed any and sometimes none. I also noticed that no matter where we were located, there was never an indication of a 4G connection in the home screen icons. So I then tried changing the network connections to the following that resulted in the 4G icon displaying but unfortunately voice and text stopped working completely (got an error message – no SIM card or SIM card error):
Network mode – LTE/CDMA
I also set the APN to NXTGENPHONE and its' settings according to the AT&T website
I’m hoping there’s something I can change to improve the connectivity/reception on this phone since my wife really likes everything else about it. I would appreciate any help/advice you could give.
Thanks

What is your signal strength on both Samsung and lg?
Download an app called advanced signal status on both phones
What is the db? And signal stength?
One should be a minus one should be a plus
They will also fluctuate so give me the number it usually sits at

OK - Thanks.
If your IEMI is not registered on their network (likely, as you didn't buy the phone from them), see if they will register it. May require that you buy a new LTE capable SIM card from them.

That is a very weak signal.
Here's the catch
Both phones should have displayed the signal strength
So you are using 2 different network bands on the phone
It's either your sim, or select another band on your LG G4
2G/3G that your phone is currently running on is an older network, and since your Samsung is not registered on that network you have selected wrong band on your LG G4 or your sim card is not compatible to operate on the network you want to be on

I have several ideas for the reason of your problem. First of all, is everything ok with your SIM-card? Wasn't it damaged when you installed it in the new phone? Also your type of card can be not suitable for this certain phone model, unfortunately that happens sometimes
I'm really surprised that the customer service wasn't really helpful in your case, as I know they should check such cases personally in special centers and fix the tech problems. I recommend you to call them again and ask about this
And nice 4G connection demands a constant good signal. It's a rather common problem for the phones but not because of the bad networks but your current location, there are many places where this signal is very weak I had such problem in my house, I ended with buying a signal booster https://www.myamplifiers.com/4g-lte-booster/ which in my case was really helpful. However I suppose that your main problem isn't the signal but your phone, I think that you really need to check it in a special service center because all these problems mean nothing good for your device, especially the new one
I am merely speculating but depending on how old your last sim card is, it could just be as simple as getting (here in Canada they're like $5-$10) a new up to date one. It could also be an issue with the phone antenna itself?
Network mostly recovered
Just install advanced task manager from play store and set it to kill task every 15 min or so. Network issue will be gone. This is what worked for me. Thanks.

Hey... I had this similar problem. I bought an Iphone 9 and and I had many problems with my signal. In many times, my cell phone showed "1 bar" of 4G, so I couldn't do almost anything. Fortunately, a friend told my about an signal booster and now my signal problems are done. I bought it in a website named amplificadordesenal.es and it's been really GREAT!! it cost a little but it was the better solution.
Hope this can help you
