Hey all. I just got my hands on the note edge from a friend. He says its unlocked although it was originally at&t (symbol on back cover). I put my tmobile sim in there and it seemed to work just fine. I was able to make calls and send and receive texts, etc. I did notice that I was unable to get data connectivity like 4g/LTE which I was getting on my old unlocked s4. It would just show the bars but not 4g/LTE/3g symbols. Are there any fixes for this or tricks to get the data to work or will it not be able get it at all because it was at&t to begin with and Im using a Tmobile sim? I would not call myself an expert around phones. The most I have done is install a different ROM but that was with supervision haha. I also tried to search for USSD codes but didnt have any luck with that.
Any help or advice is appreciated!
-Thanks

Did you have to unlock the phone to do that?
I called AT&T and they said that they don't have the unlock code since they don't even sell the device, but that it works on sims outside the US. She seemed to imply that it won't work on tmobile but that if I go outside the US, and just put a sim in, it will work without me having to unlock the phone in anyway.
Can anyone verify this?
Thanks

Most customer service representatives are pure idiots .... Nexus S is a Google phone , so it's factory unlocked to any SIM card you use with it(you may or may not get 3G on other networks depending on the other network 3G frequencies , and if the forgein network has 3G on 900/1900MHz it will have 3G on this Nexus S)..
Hope this helps..
Well I went to tmobile and the guy put in a sim into the phone and the phone got no reception nor did it seem to recognize the sim at all.
So it seems that it isn't unlocked.
I tried putting in this code: *#7465625#
Its supposed to tell you if the phone is unlocked or not, but nothing happens, it just says: Connection problem or invalid MMI code.
I don't need it to work on tmobile, but I do need it to work on foreign simcards. And I saw on other forums that for some people it worked on tmobile and others it didn't so there doesn't seem to be any clear answers.

you have another issue here , check your phone
Thanks for the response.
What do you mean by other issue and how should I be checking my phone?
In any case, I put in a simcard that my brother gave me which I believe is from Mozambique on a carrier Vodacom. It asked for the code of the sim when I put the phone is as always, and so I got in putting in 0000.
It then showed no connection to anything whatsoever, also as always.
Keep in mind I did have wifi on.
Then all of a sudden it asked me to update my phone and install something. So I just said yes and it updated and rebooted.
All of a sudden I have bars here and there and it recognizes that tmobile and AT&T are in the area. I also saw I think at the top of the notification bar when I pull down the notifications tab, it said Vodacom. Of course I get no reception whatsoever but that is expected, this sim was a gophone sim in Mozambique.
Does this mean that its unlocked if it is recognizing another sim, even though no confirmation of reception? I plan to try again with tmobile now and perhaps make sure I have wifi connection while doing so and leave it in for longer.
Thanks and please let me know if you have any thoughts.
what ROM you're on now?stock or costum one ? you also might consider a FULL phone wipe.because this might be caused by a difference between at&t apn or other Sim data and the other .check for that
I'm on stock 2.3 that the phone came with. Haven't messed with it at all.
So I assume you saying that if I want to switch to another sim, I should do full phone wipe then? so that the at&t apn doesn't confuse it?
IF it doesn't work with tmobile again, I will try taht, and I will also try to learn what an apn is.
Thanks for the help.
Might work or might not !!! backup all your data and apps first then use the shotgun method lol
But what I am sure of is that Nexus S phones are always unlocked and SIM free..
My husband finally let me root and rom his S3 (I have a Gnex). Unlocking the bootloader and rooting (using Odin) went well. When I installed SlimBean+GApps, however, we started having an issue. He kept losing 3 & 4G signal. We didn't know about the roaming issue, so I had not backed up the IMEI. I flashed Clean Rom, and the issue is partially fixed.
The phone's signal is fine now, 3-4 bars 4G most of the time. The trouble is, we can't dial out to any numbers, and any calls to the phone go straight to voicemail. We've pulled the sim card and let it sit for a bit, but that didn't help. Dialing *228 (as Verizon tech support had him do about 4,583 times) just brings up a message about the phone being activated by the sim card, and roaming capabilities being updated. All tech support had to say was that Google Voice was probably the problem, even though we've both had it for ages with zero issues. :/
Any ideas? I don't really want to unroot and take it in to the Verizon store, but I will if there is no alternative.
EDIT: Just discovered that 4G is only working when "Preferred network mode" is set to Global, rather than LTE/CDMA.
*228 is for 3g phones only, it does absolutely nothing for LTE sim phones. Here's your solution btw.
I knew it! I kept telling them I didn't think that was supposed to do anything when I have a sim card. Crazy first string tech support. They also didn't know my battery was removable.
Will try the things listed in that link, thanks.

Haha Verizon lost credibility with me when I rented their global phone for travel last summer and when I got back to the US the instructions to get my GSIII working began with dialing *228. There wasn't even a warning about it being unnecessary for LTE sim phones.
Good luck and let me know how that goes.
I picked up a mint verizon s3 local on a trade for some scrap phones I had. So here is my issue. I put in a sim(at&t) and got the switch to global notification but it never gets signal. Phone info shows -120dbm 99asu. Figured since it was free I would play with it and installed hyperdriver rls 16 still nothing. Took everything back to the first stock ics nothing. Currently have it on jb 4.1.1 nothing. I started to wonder if the radio was trashed so I dialed 911 with no sim in the phone and it popped up 3 bars and made the call.
Am I wrong in thinking this phone will work on US networks with a sim? Anyone ran into this problem possibly can maybe point me into a direction to get it working. The phone is clean and not blacklisted and it reads the different sims I have put in it I just can't get any signal to pull up other than an emergency call. I know there is signal my s4 is on the gsm network sitting right next to it.
Thanks in advance, I have been searching since yesterday for a solution.
****update.....Went ahead and took it to 4.1.2 stock and happened to find an old verizon sim. Phone picks up verizons network without issue. Still nothing when using the at&t sim.
It isn't working for AT&T because you haven't set up the appropriate APNs for that network. Google AT&T APNs. Reboot after making the changes. CHECK FOR TYPOS!

I thought I would at minimum show signal even without adding the apn. From everything I have read its talk ready just inserting the sim. Will look at adding apn's this morning.
Final update. Still no joy on getting it to work and I listed it for sale.
There's a thread about getting vzw s3 to work on T-Mobile, I'd imagine you'd need to follow a similar process. And FYI, all phones will call 911, sim, no sim service, no service, they'll call 911. My niece was playing with one of my sisters old, no longer connected phones. All of the sudden police and ambulances showed up. She had dialed 911, they tried to return the call unsuccessfully so they used the phones GPS info and showed up at the house.

Recently purchased the Xperia Z5 (E6653) and I am having some serious issues with calls on T-Mobile USA.
Calls don't dial out (or it takes multiple tries) and calls won't come in when the phone is connected to 4g (LTE); they go straight to Voicemail. I missed about 12 phone calls yesterday - just getting voicemail after vaoicemail till I realized something was wrong on my side. If I toggle off the LTE it drops to Edge (no HSPA+) and calls come in fast and outgoing calls are made with no problem.
I tried to reset the phone, then repair the software with the Sony Companion app. Still same issue. Looked online for the APN settings. Tried various ones. Re-downloaded the Internet/MMS via the phone itself. Same issue. Tried my wife's sim and it was still doing the same. I have a spare 5s and it worked fine both incoming and outgoing calls. So, it doesn't seem like its the sim card.
I have Rev 2 of this phone so I am not sure if that is anything to be concerned about. Am I missing something...any help on this would be appreciated.
Thanks.
Maybe flash a T-mobile firmware with flashtool?
Or Flash 209 firmware meant for usa?
Or wait for someone here that use this phone on T-mobile.
Are you on band 12 LTE by chance
No, it said band 2 with LTE Discovery. I am on the verge of sending it back. Swap it for another one. Let's see.
From what I have gathered/read - it should really be straight forward. Pop in sim, load Internet settings, and it should work on T-Mobile. The APN settings are correct.
Doesn't makes sense for it to completely not work on 4g and go to 2G (Edge) while skipping 3g. I'm wondering if the baseband might just be wonky. I just see this as causing more problems down the road which I don't want from a $520 device.
Any advice is welcome because I am ordering the same phone again. Lemons are always possible.
Could it be possible because I live a relatively rural area (East TN) and the phone does not support AWS? Since it doesn't support T-Mobile VoLTE and doesn't have AWS it is defaulting to 2G? Is this an issue in all areas or just rural? Apparently the E6683 variant doesn't have this problem as it supports AWS.

That means ur phone should work fine with T-mobile,maybe go and get a replacement from where you bought it.
Hello everyone, im new here kept searching everywhere for solution for my problem without any success. In may 10 i bought SM-G955N KT module, it was working great with 2g / 3g / 4g / LTE / LTE+, i went out of usa for almost 3 month and when i came back my phone doesn't work well with tmobile, i can send msgs use lte internet but i cant do calls at some areas, some times i have full lte bar and when i try to make a call it goes to 0 signal bar, i called tmobile many times about the issue but no solution i found out that they did upgrades to their towers in the period i was out of usa from may to august, right now i cant use the phone as any normal person its been a month that i cant use the phone at my house and some areas, i can make calls sometimes if im at different tower locations. Question is, is there any solution for this problem since tmobile did those tower upgrades its screwed up everything..... should move out to att or verizon or what should i do. I really need help with this problem its been a month, any solution would be welcome if it requires root or not i dont care i just want to find a solution for this,
Thank you.
Have you tried resetting your network settings and/or getting a new sim card?
Its not the sim card i already changed it to a new one also i tried it on a iphone 7s plus and it works fine, my phone is bone stock no root no custom software alsi its the korean version when i looked around i found that tmobile did some network upgrades from may to aug and thats when my phone got screwed up, i was albe to play with the ims setting and i got the phone to recive calls but i cant make calls, does my phone screwed up because it has the korean csc and the stock firmware or whats going on here
I'm not quite sure I understand your experience. From what I am reading, you went to Korea, got the G955N (which I bought for both myself and my wife), and then came back to the states and can't get it to work with T-Mobile?
I tried to get mine to work with T-Mobile and have experimented extensively with different CSCs and ROMs.
I eventually went over to AT&T
I've also had a rather extensive experience of how to get 4GLTE working here in the states with AT&T.
Feel free to reply here or DM me if you wish.

Hello thanks for your input, actually i bought the phone in the box brand new from amazon, it came here on may 10 i used it for 7 days 4G LTE 3G works great then i had to go out of country for 3 month i came back at the end of august to find that tmobile did a huge tower upgrades in my area, since i came back i wasnt able to do calls and receive calls, i was only able to text and use LTE internet but not calls, i went to different towers area and i actually was able to make calls but not in every area because some times my signal bar goes down to 0 or even 1 signal and i cant make calls still but my other friends who owns iphones or usa version of android works fine except me. Yesterday i edited the IMS setting im still on stock fw and i enabled every single feature there and i was able to receive calls in my area but still i cant do calls, i wanted to make sure if im gonna follow the steps here in this guide i will be able to use TMOBILE CSC with the korean stock firmware and get the features of tmobile as VOLTE and WIFI CALLING etc with the right CSC for sure and without tripping knox
Thank you
Hi, I did some extensive searching and was not able to find a solution for this.
I've got the SM-G955N, and ran into the same issues as other users in this thread with T-Mobile, has anyone found a workaround to unlock the LTE bands necessary to make the SM-G955N work with T-Mobile?
I didnt find solution yet too, i dont know what to do i gave up i tried everything on the official software no root.

I had a phone with the Korean CSC as well, N phone as well. I left the CSC alone and it worked with T-Mobile and ATT here in the US just fine, last fall.
I later changed the CSC to XXA, and still works well. Just tested it this week with T-Mobile, and it's working. I have to say, that locally, T-Mobile has much poorer spot area service than ATT. Kinda puzzling, but that is the way it is.
My phone is rooted, so it make things a bit more handy to mess about and return to my previous setups.
