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!

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

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..

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

Anyone using this phone on ATT

I understand that this phone has the same hardware and supports the ATT LTE bands. I am done with locked bootloaders, I need confirmation someone is using this phone on ATT Network w LTE successfully without any hacks..
Any other feedback will be great (call quality, radio performance on ATT network)
Seriously pondering getting the T-MO version. I am hoping I can get one off contract.
TIA

I am currently using the phone on at&t. LTE works. Just make sure you set your APN right. I just disabled WiFi calling because it is not supported.

I'm considering buying the TMO variant to use on AT&T as well and I have a few questions related to this topic:
Would service reception be restricted to just LTE or can the T-Mobile S4 still receive AT&T's E, 3G, etc as well when used on AT&T's network?
Also, and I'm sure this is dependent on the answer to my first question, would the T-Mobile S4 work with the AT&T 3G Microcell?

hard to answer; it really depends on the area, but for the most part im pretty confident in saying t-mobiles LTE is faster.
see attached photo

I've been using the T-Mobile version on AT&T for a few days. I unlocked using the debug menu instructions in this forum, setup the AT&T LTE APN and set the preferred network to LTE. It works fine on LTE, hspa, etc.
Speed test results were 53Mb down, 19Mb up, 66ms ping in Raleigh, NC.
I gave away my microcell with my POS iPhone because the Samsung phones performed OK without it. So, I can't answer whether the T-Mobile version will work correctly with a microcell.

Hi all,
I have a Galaxy S4 I9500, I keep my brightness at full all the time. When I finish playing games even "subway surfer" for 10 minutes, and exit to the desktop, I find that brightness is lowered alittle bit & increase gradually to the previous state which is full brightness (from 5 to 10 seconds). Could this be a result of that when playing games, the device uses the 1.6 quad core CPU and upon exit it takes alittle time (those 5 to 10 seconds) to shift to the 1.2 quad core CPU?
Really need your help.
Thanks alot.

So it seems this is the perfect phone to use on AT&T due to all that bootloader problems and crap on the AT&T version.

So folks still running fine without issues with this device on AT&T's network? I know LTE bands over lap so those are fine and the specs for the other frequencies all line up too but any problems with any data or voice stuff at this point after more time has passed? Including text and media messaging?

I had left an area with LTE coverage before I was able to network unlock, so I can't comment as to how LTE is working... but I've had no problems using it on Edge or 3G, texting/mms, etc. It even works flawlessly on my Microcell with no modifications other than the network unlock.

Mohan,
Which phone are you getting? The T-mobile version or the Google S4? I read online that the Google version of S4 is the same as the T-mobile version. I'm a T-mobile customer but I want to follow you using the Embryo rom on your new phone selection and hopefully get wifi-calling feature. I'm currently using the Embryo rom on my T989. Thanks.

adding an APN ... issues
lemme ask what will undoubtedly be a noob question. i've unlocked my T-Mo S4. confirmed. i popped in my AT&T iPhone 5's SIM card and boot up. i see that i have a signal, am able to make and receive phone calls. but no data. when i look at the APN, i'm seeing Cingular APN. what gives? i thought the phone would auto-detect and attach to the correct APN and i'd be good-to-go. thoughts? do i need to manually add the APN? I have all of the info necessary. when i try to add the APN, i am able to get to the proper menu, add all of the info. however, when i try to "save" the info, it never shows up as an APN for me to select. so whatever info i've just entered was never saved.
help!

Lte on m919v 4.4.2

OK i have tried to find the answer to this question i have a S4 M919V ( Videotron/Wind) on 4.4.2 (M919VVLUFNB5) And I'm currently with virgin mobile (Bell) i have evething set up to receive LTE on the phone. the sim card is LTE ready but i have no way of getting the phone to receive it.
I've tried to go into setting ( phone dial *#2263#) of that but nothing worked.
I don't mind rooting my phone but would love to get LTE without having to sell my phone and buying another one

have you tried the settings here?
Settings/More networks/mobile networks
Your Network mode should show LTE,WCDMA (auto connect)
if not, tap on the network mode and select the LTE/WCDMA (auto connect) option and back all the way out.
Turn on airplane mode for about 30 seconds and then turn it back off and see what your results are.
You need to be SURE that LTE reception is possible where you are trying this. After all, no matter how good your hearing is, you won't hear me talking if you're out of earshot, right? LOL
Good luck!

Yeah I've tried it and for some reason I don't have this option but your right about checking if the lte is available before doing anything

Thats strange, this issue has been encountered with rooted phones running stock/custom roms while running some mods.
You may have to do a factory reset, or stop by a TMOBILE store and let them check it out.

Could be that it doesn't support LTE from your carrier.. I think it may be capable to support LTE but its disabled on that model.. I've seen people flash M919 modems and gotten LTE to work. Just make sure you do some research, and more research if you device to do this

I've been rooting my phone as if it was a normal t-mobile m919 but I tried searching for into to see it there was a way to simply make my V (m919V) disappear and solve all my problems but nothing yet I know you can but as far as warranty, brick and risks go I have not found much information regarding this issue and that why I started this post
I wanted to say thank you to everyone for your help and suggestions

OK I've done some research and it seem that the m919v has the lte hardware to run the frequency 700
( http://www.morecellphone.com/compar...vs-samsung-galaxy-s4-lte-gt-i9505-64gb/340724)
And that virgin mobile (bell's network)
(bell is one of the biggest telecommunications companies in canada)
has this frequency on their network
(http://en.m.wikipedia.org/wiki/List_of_LTE_networks)

The only thing is that the lte frequency off 700 was lunched in Ontario last month and I'm in Montreal
But the fact that t-mobile only has 1700 and that virgin uses this here means that the phone isn't the problem and with this information, i've concluded that it a software issue

[Q] T999l not connecting to LTE

I just purchased 2 T999l phones and had them activated on Metro PCS. My wifes phone has got LTE from the moment it was activated. Mine will connect HSPA+ but not LTE. All of our settings are the same except when I go to service mode mine doesn't show LTE. Is my phone damaged? Can I fix it? Am I over looking something?

Can you download this app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo and post what it says about your bootloader and model number?

Could be you need a new sim card too. Swap Sims in both devices and see what happens.

Metro sets the SIM to the IMEI so it wont work in the other phone.
Network mode is LTE/WCDMA/GSM(auto connect)
APN matches the working phone. Besides you can't change the T-mobile APN settings.

Well that sucks! Didn't know that, sorry.
Are both devices used? It is possible one is defective or has been used/abused to the point of not working right. I'd take it to a Metro store and ask them to try it by registering it with one of their Sim cards and testing it out. Have you tried flashing stock firmware? If it was rooted/flashed in the past, maybe they just didn't take the time to go back to stock correctly.
