No Data on AT&T for unlocked T-Mobile N2

Hey all, been lurking for a while and found that many of you have unlocked Note 2's running on AT&T. I bought my unlock code and all is well on the voice front, I just can't seem to get data working (not edge, not 3G, not HSPA+, nothing). I've tried the various APN's floating around, I've tried selecting CDMA ALL for the frequency band, and I've selected AT&T and "registered on the network" using the automated feature of the phone itself. Still nothing.
When the AT&T version is released, will I be able to flash the ROM and make it work as if I bought it from them?
Thanks in advance for your help.

Thats weird. I unlocked mine and got tge cingular apn automatically .

Do you have the right sim and have you got at&t to update their system so it can work? Tell them you have a Note 1.
That's what Indie. I have data (but not LTE)

This is the answer I needed. Thank you! I ended up going to the AT&T store today. They said that for some reason I didn't have a data plan anymore (weird because I traded my iPhone 5 for this phone! They subsidized it.) They couldn't get my IMEI to work in their system so the saleswoman used her own IMEI to get me going.
I had been to the AT&T Store once before to trade my nanosim for a microsim, but the phone wasn't unlocked at the time so I couldn't test it out. They scanned in my phone but I guess it didn't take. All is well now, I have 4G (but not LTE, but it doesn't matter because I'm moving to a non-LTE city in less than a month).
It works perfectly, I put in the APNs from the Galaxy S3 on display that the AT&T Store. Decent speeds, awesome phone. Thanks everyone!

I wonder what speed you can get on att 4G network with TMO phone if you have tested, one of my buddy has a international version he gets 3 - 6 when did a speed test

That's what I get. And honestly, 3-6Mb/s is perfectly fine for me. I'd like to get LTE for the time I'm here but it doesn't bother me that I don't. At some point one has to question that value of 100Mb internet on a 3GB data plan.

LTE is locked as of right now on the tmobile GN2

I know it isn't AT&T but it took a while to get Solavei APN working on my phone. I played with the settings forever with a customer service rep before I finally got it to work. MMS & internet work great now! Can't wait for LTE to launch!

i got my tmo verion unlocked. I purchased a 50/mo at&t go prepaid, and I can see 4G in the status bar.
Hope this helps

Bell i317 LTE APN help?

I just recently bought a locked Rogers Galaxy Note II i317M and unlocked it using cellunlocker(dot)net; however, I am not getting a LTE signal on Bell for some reason — it's always just "4G".
I talked to a rep and he said that it should work since im in a LTE covered area. He also said that he can't help me further since I didn't buy the phone from Bell .
Anyone know what's happening here? Did the unlocking mess it up? Is that even possible?
I'd really appreciate any help. Thanks.

What are your APN settings?

Bell does not have a different apn for lte and hspa. After flashing some at&t roms, I am not getting lte at all. But the stock room is okay .

I'm on Rogers and couldn't get on LTE. It turned out to be my old SIM. Rogers replaced it and voila, LTE. Not sure if Bell has a similar issue with older SIMs or not, but maybe it's worth a try.

i flashed the Rogers modem. Works now.

Yeah check your apn settings and post them here

You don't need an LTE plan on Bell.

Sometimes changing the apn to proxy.bell.ca instead of pda.bell.ca would fix the issue. . Although tried both ways on my SGN2 - both worked out well..

Iniquity0411: all the older UMB, UNPDA and any other unlimited data plans are not eligible for LTE. If you want all the nitty gritty details, you should be able to find relevant posts on HowardForums.

lte not working for me
hi guys i recently flashed miui for my note 2 and noticed im only getting 3g, my APN settings look the same and ive also played around with them but always end up with either no internet or only 3g. any suggestions?

As a canadian multi-carrier cell phone salesman you do need a data plan, sim, and phone all to be lte enabled for lte service. If you are on a plan roughly two years or older you most likely did not get upgraded to lte data. This sounds like your issue here, and you would have to go talk to your corporate to have the plan changed over. I'm not sure if its a personal under a corporate (this case changing should be easy) or a giant bucket plan, in which case good luck.
Rogers is the only canadian carrier to have an lte APN.
and lastly your bell micro sim should clearly be labeled LTE, and for others FYI Telus sim cards should be V31, and rogers I believe its B010 if memory serves me right.
On the note 2 lte is already a default setting if already enabled.

well i guess then miui for the note 2 is not an lte rom because ive checked and rechecked my apn settings, and i have all the above that u mentioned, the stock rom (4.1.1) had lte but when i flashed miui all im getting is 3g.

apn settings all blank i317m
I did something in odin.
I am on 4.3 official firmware but I have no mobile data. I checked my apn settings and virtually all settings are blank. Not set.
Help please
Thanks

Can't get my Verizon Note 4 (n910v) on T-Mobile. No service.

Hello everyone,
I was using the Verizon note 4 on tmobile until I got the 5.0.1 lollipop update. Now it won't register on tmobile at all, and there is an "x" next to the signal meter, indicating that it isn't getting any service. I triple checked my apn settingssettings, network modes, restarting. Nothing works. Did the lollipop update simlock the phone?

Anything is possible culprit..I would take out the battery and make sure the Sim card is inserted properly..and if that doesn't work do a factory reset..

Getting TMobile 4G_LTE Working Again
Hi,
I had the same issue with my Galaxy Note 4 (SM-N910V) edition. I needed to go back in and add the APN for TMobile US LTE, then all was well. I have included snap shots of mine for reference. Also, make sure you set your "Network" to Global.
Best of Luck

In my situation, I'm a tmobile user but had the chance to get a verizon note 4 at a cheaper price. At this rate though, I may just sell it and get a tmobile version.

Has anyone figured out the issue?

I got another N910V with 5.0.1 today, it has the same problem (not being able to use other carriers' sim cards). I'm pretty sure the 5.0.1 locks the phone. WTF Verizon??

Sorry you're having that issue. I bought a Verizon Note 4 on swappa the other day that already had 5.0.1 and Build ID ending in BOAF. I was able to get signal on it, no problem. Downgraded to 4.4.4 and service was still available. Have your SIM card replaced at a Tmobile Store to see if that resolves the issue. I'm curious as to your APN settings and whatnot.

Honestly I don't think they did that .. I tested many sim cards and it works all the time.. try maybe new sim?

I have a verizon note 4 and a T-Mobile one too which i bought because of not 100% reception.. My friend updated to lollipop he has verizon note 4 service is working perfectly , try keeping the network mode at lte cdma for little while and then go back to global , or try an at&t sim card in it .. if your phone just got bad esn T-Mobile will not work on it too as T-Mobile do not let any bad esn phone run on their network .. i am 100% sure lollipop has nothing to do with it

Well I can't say for sure either, but there are too many people having the same issue (no service on tmobile after upgrading to 5.0.1) to deny that 5.0.1 has anything to do with the problem. Also, the ones that are saying lollipop has nothing to do with sim lock, can you guys check if you're using 5.0 or 5.0.1? The ones that are saying that they stopped being able to use the N910V on tmobile are all on 5.0.1.
EDIT: If you're on lollipop + tmobile on a n910v, can you tell me if you're using the new ISIS sim card?

trouble with note 4 mobile hotspot
Need help, when my verizon note 4 was root, I was able to turn on xposed tether for mobile hotspot. I was able to connect other devices to it, but had limited connectivity meaning no internet. I tried everything but had no idea. I almost want to give up note 4 even love it. Is it because xposed tether does not work on note 4? I have same issue with foxi. Is sqlite editor better, can someone help me with setting for sqlite for Verizom note 4 to try? Thank you

Has anybody been able to get it to work on metropcs? I get an x next to the signal bars. I used the fast.metropcs.com apn and i tried with the 3 network modes ... I was able to get it to work on tmobile but not metro

Found solution.
For those having issues with not service when changing SimCards after 5.0x.
The solution is http://forum.xda-developers.com/android/software/debloater-remove-carrier-bloat-t2998294
Just disable Verizon activation (VzwActivationAgent apk) app. NO ROOT NEEDED
I also disabled some Knox services that where already pre-marked.
Now I have service with T-mobile Sim and don't have the annoying "unkown sim" message.
The tool is created by @gatesjunior so, show your appreciation on his thread.

I followed the instructions and also disabled "VzWActivationAgent.apk", still unable to get TMobile sim to work. Any other suggestions? Thanks in advance.

Unlucky with Carrier Options on AT&T in USA after flashing.

NOOB / FNG here and my brain is fried. I have purchased at Best Buy an unlocked GS9 SM-G960U1. I have flashed with ODIN and AT&T firmware. I get the ATT bloatware and welcome screen but no IMS Features, VOLTE, WiFi Calling etc.
I have tried different versions of the AT&T FW with same results.
My AT&T SIM card is 2 years old and out of my ATT Unlocked GS7, which has all working IMS features.
Forgive me if this is a repost. I have read and studied and cannot figure where I went wrong.
Thank you in advance for more of your wisdom here. It is much appereciated!!!

When you flashed the AT&T firmware did you have your sim card in the phone? The other thing you can do is have At&t hard set your Galaxy S7 IMEI in their system(put the sim card back in your s7 and call AT&T and say your hd voice and wifi calling isn't working, and they will ask for the IMEI).

How long has it been? It sometimes takes a few days for some features to show, especially from T. I'm guessing you power cycled your phone with the Sim card in it also.

Yes, I flashed the phone with the AT&T SIM card inside the phone. I called AT&T and spoke to a rep who wanted to help and put in a ticket for me but he was told no and that I had to flash the FW on my phone.
Rebooted and waited several days, IMS setting still greyed out in the *#*#4636#*#* dialer.

So this is the mobile carriers working end users over.
According to Android and Google the idea behind Preferred Carrier Options and Unlocked handsets was to be that each carrier would have an App that the end user could down load to use these IMS features on their unlocked hand set.
To date, no carrier in the USA does this. So why lock it down?
The idea was not to do what AT&T is doing.

Also, the second I remove my AT&T SIM card and insert my MINT SIM card my IMS settings become available to select/unselect.....

Note 10+ unlocked Tmobile issues

Just got my note 10+ and I'm absolutely loving the phone, but the service on the unlocked phone isn't to good. First off when i make a phone call it doesn't stick to LTE it goes to H+. When i hang up the phone it takes forever to switch back to LTE. What's the issue? Maybe because I transferred my data from my note 9?

What else are you seeing besides the lte any issues with wifi calling/volte/video calling/visual voice mail?

Wifi calling works. I have really never used visual voicemail. Volte is the biggest issue for me. Video calling doesn't work since it doesn't have the t mobile firmwire on it. I will give it 24 hours for the SIM card to be fully configured if not, I will be flashing the tmobile firmwire

I'm using the unlocked model on T-Mo. WiFi calling and VoLTE work fine.
Only thing I noticed was the data speed seems slower. I have two lines, so I tested them side by side
I had my Note 9 (running T-Mo firmware) in one hand, and my Unlocked Note 10+ running the factory unbranded firmware in the other hand. The Note 9 was pulling 80 Mbps and the Note 10+ was pulling 60 Mbps.

Easiest way is to install t-mobile firmware on unlocked version to enjoy all the benefits along with faster carrier updates https://www.sammobile.com/sams...ote-10-plus/firmware/SM-N975U/
