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

Just started a new thread about this...http://forum.xda-developers.com/showthread.php?t=1971879...then I found this one.

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.

Yes I am. I had to add the apn and then choose lte in the network section. Works great though.

what is the apn setting bc im looking to switch to t mobile with the s3 att

I am NOT able to get this to work at all on mine. I am unlocked, rooted and I am using a red pocket sim that uses AT&T towers.
Any suggestions?

Did you get an unlock code from tmo, a 3rd party, or some sort of debug method a la s3 and note 2?

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?

Whos Lte is faster tmobiles or att.

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!

tmobile note 4 reception/LTE on ATT network

I've been hearing a lot of stories that users using a t mobile note 3 on the ATT network were having issues with reception and getting and holding onto LTE. Seems like an important enough topic to deserve its own thread. Initially I'd like to see issues with the Note 3 as I'm still deciding which carrier model I'll go with, but eventually we can put information on the Note 4 when its released.
I may just eat the locked bootloader with ATT. Really the only things I would miss are xposed modules and titanium, I'm not into custom roms anyhow. Tmobile reception is just too horrible in my area so staying on their network isn't an option.
EDIT: Also wondering if the Tmobile phone can use the ATT Microcell? Also can the Tmobile do tethering on the ATT network?
Edit2: I'd love to see some db numbers as it seems just judging reception by bars is highly inaccurate, most users don't even realize tmobile uses 4 bars versus ATT's 5 bars.

I have the at&t note 3 and the the tmobile note3.I have been using the tmobile note 3 on at&t service since the day it came out. I get the same coverage as the at&t model including lte with no problems sometimes better on the tmobile version. I will be buying the note 4 on tmobile Again to use with my att service until the note edge comes out. I will be buying the tmobile note 4 version again thus year because of the att locked bootloader crap. I can live without the roms but not root access, xposed and wanam apk take care pretty much of the rom stuff. It takes to long to get root on the att model. Look how long we had to wait last year just for root and the bootloader is still locked tight, with no promise of ever being unlocked. The tmobile note 4 will be probally rooted in the first week if release., Bye, Bye, AT&T PHONES ,YOU SUCK AT&T..

I was one of the people to use the TMO Note 3 on AT&T who had reception issues. HSPA+ reception was fine, LTE reception was awful. It wouldn't even pick it up in areas where an iPhone 5 would sit with 2 LTE bars.
Having used the TMO S5 on AT&T, I didn't have any problems. The note 4 should be fine.

Had nothing but LTE reception issues with my TMO Note 3 on AT&T. For this alone, I'll pick up the AT&T Note 4. I don't have much need for root nowadays anyway.

I've been using the T-mobile Note 3 on AT&T for a year now and haven't had reception issues. It does switch to HSPA+ from LTE earlier than my ATT note 2 did but the db signal strength was the same.
Having root is an absolute must for me. I have to have adaway, truecrypt (EDS), debloat, and Titanium backup. I would pull my hair out (what's left of it) looking at all the ads on my phone.

I'd rather have reception than the very few remaining reasons to root these days as I use my phone for business and it's crucial. It may be a small difference or large, but I can't take that chance. Really the last reason I root is titanium and xposed.

My G3 (AT&T variant) has real trouble holding onto LTE, and my Nexus 5 was much the same way.
Makes me think a lot of it is just their network.
I had much better LTE signal/performance on T-Mobile. But better overall voice coverage with AT&T.

I'm also on ATT considering getting the TMo version for unlocked bootloader. Is there a map that shows which bands my city uses (or does it matter)?
Thanks,
-PDX

I am getting the TMO N4 to put on AT&T also. I don't have any plans to put any custom roms on it but I figured if I was going to pay full price for a phone I might as well get all the options. I am trying to decide if I am going to pay to have it unlocked before the 40 days that TMO requires or just wait it out.

If root is an absolute must for you, then what's going to happen when root is completely locked down? It seems like things are going that direction. Will you not use a smartphone anymore?

I'm hoping that you're right and it's not just wishful thinking. I don't need roms, I really just need root.

Ya, they are slowly backing us into a corner. I don't like google's stance on no sd card slots with nexus devices. Soooooo, as long as T-mobile keeps unlocked bootloaders (which is a free pass to root) I'll probably stay with Samsung.

It's already here. Chainfire released it a few days ago. (for the t-mobile version)

I've been using an unlocked T-Mobile note 3 since it came out with no issues with LTE speeds/coverage. I want the note 4 but hadn't read anywhere that it was confirmed to have an unlocked bootloader. Has anyone confirmed that the bootloader is unlocked? Also are the bands going to cover us for all our services on att? Also att is coming out with LTE-A soon, will the note 4 unlocked support it?

Hopefully it's the same case for the AT&T and VZW versions. I really don't want to have to sell it immediately and then go through the process of buying a TMO one.
Would've done that outright, but I can't afford it at full retail. Had to go with a 2yr upgrade and the BB promotion.

u-dig?
Of course the tmo version doesn't work perfect out of the box, but after some minor modifications it will work beautifully!
I've had a tmo note 3 over a year with excellent results!!!
You will need to configure the build prop and configure the apn for ATT..
Then enjoy!

Can You unlock an ATT Note 4 To work on T mobile? I tried out The service I have never seen data speeds so fast before In my life. 70 down 20 up. Will the bootloaders Unlock if I have The phone unlocked for their Network?

I have read some posts here and there about it, from what i could find out it does work with tmobile, ive seen some people had problems with lte, but i also seen others had no issues at all with it. I cannot remember where i seen this stuff as it was a while ago when i was looking into it. Search some of the posts for note 5 and others

Yes.
I have a Sprint Edge+ and am currently on T-Mobile.
The only unlock i've found that works is idoneapps. (requires root and tripping knox)
They want money though.
After getting unlocked with their help, I had to flash a stock Sprint ROM to get LTE working.
I'm getting about 60Mbps up and 30Mbps down on T-Mobile with my Sprint Edge+
Good luck.

can i flash USCC N5 with AT&T N5 firmware

hey guys/gals i have a USCellular Note 5 which is unlocked and recently switched to AT&T and everything works but MMS and 4G is flakey, usually bouncing between 4G and H and H+ (on the signal)
i dont feel data speeds suffer but speed tests show it is compared to my LG V20, so fear signal reception could be different that an AT&T note 5.
anyways, does anyone know if it is possible to odin flash tan AT&T rom into my USCellular phone and make it run properly on AT&T.
the NOTE 5 is of course unlocked and when looking at the specs is only missing 2 cellular bands and has more bands in 3G than the AT&T variant.
anyone have a clue, i would not like to brick this phone beyond repair because i can still sell it for someone wanting a USCC variant, but am willing to flash it with an AT&T rom if that will fix the MMS issue.
the APN's are correct, but i did install KIK messaging and when setting MMS to manual APN it immediately came up with a uscellular APN which really makes me believe somewhere in the phone its still holding a USCellular APN and not using the AT&T one even though it is set in the Network settings of the phone.
the phone did download the small october security update, but it still isnt sending mms messages.

No, the branding will stop and fail Odin.
---------- Post added at 02:52 AM ---------- Previous post was at 02:51 AM ----------
Also if the APN is force switching. It means the AT&T APN settings are wrong.

I found it!!
The APN proxy was misspelled.
I don't know if the guy in the store did it or if it pulling from at&t but everything was right but the proxy was .ent instead of .net
I never changed it cuz I always looked at it and said yup that's right
Last night I noticed it and now it works
Just gotta keep an eye on the 4G stuff now
