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.

Same here. Rooted, unlocked and running very smoothly, no lag at all.
Just need to get a case for it.

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.

Help please...
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!

T-mobile s4 in nz

Hi, I'm planning on going on a long trip to nz and would like to use my phone over there. I know it has to be unlocked and stuff, but once that is all said and done, would I still have to change the radio to have good signal? The last time I went on my vacation with my sensation, the signal wasn't all that great until I flashed a radio that worked well for nz users, was wondering if that'll apply to the s4 as well. Thanks.

I am an American living in Australia. (very similar mobile infrastructure w/ NZ. Kiwis to Aussies are just like Canadians to Americans)
I actually ordered the Tmo m919 sent here because all the avail bands for tmo (I still have tmo in the US). I bought it in full. Just got it a few days ago and after unlock it works great! IMO I think the tmo variant is one of the best out there. The octocores are a joke as they do not save anything on battery life not to mention performance gains. I've used tmo S3 and the tmo S4 has just about all the avail international bands out there. The only thing is there are not many dev in tmo based roms but plenty can be ported over from the i9505 variant.
On stock firmware:
1) no need to change APNS. After unlock I popped the local SIM here works great. The beauty is I pop my Tmobile SIM in, turn on wifi calling. Turn off roaming and make calls home w/ 100% clarity over wifi dialing direct US numbers w/o incurring any international fees.
Wifi calling really shines here. Will only work with active Tmobile SIM (tmo phone number).
2) All data, mms works great
3) AU and NZ do not have LTE. Just be thankful they just rolled out 4G for most networks here. There are plenty of patchy areas of 3G. Sometimes really bad in the city.
On custom firmware:
1) works even better!
2) wifi tethering hack is really good when u don't have decent internet access.
3) a lot of cheap prepaid packages here. cellular communications is about the only inexpensive thing here in AU/NZ compared with other commodities/services in the US.
*** You should call Tmo and get the unlock code well in advance. It has taken from 5-14 days to get an unlock code. My phone is newer so the free unlock method does not work (manufacture date 8/10/13). A good thing I do unlocking on the side so I plug it into my programmer box and unlock in about 3 secs.
Hope this helps

[Q] T-Mobile SM-P607T - cannot connect to 2G/Edge network?

Hello gang,
I picked up a new T-Mobile Note 10.1 2014 edition 2 days ago. So far, everything seems to be great. There is one issue however that seems perplexing. My tablet connects to 4G and LTE networks just fine but for some reason, it will not connect to 2G/Edge networks near my home. I live in a rural part of PA where T-Mobile doesn't have 4G/LTE coverage. My Samsung Galaxy S3 connects to the Edge network near my house without issue. However, my tablet does not connect and simply shows a small X where the signal meter is.
I spoke to T-Mobile tech support this morning and they seem to think that the band covering 2G may be dead. Could this be possible when 4G and LTE work just fine?
Also, the options under Network mode are now limited to 2: LTE/WCDMA (auto connect) and WCDMA only. My SGS3 has a GSM only option which the tablet seems to be missing.
I am running Android 4.4.2. Any thoughts / suggestions?
Thanks!

I can't state this as a fact for the tmo P607T but remember that the tmo 3g version of the
Samsung galaxy tab plus 7.0 had a similar situation. Users were looking to add phone functions
to this device.
Turned out on the xda threads that the tmo tab plus 7.0 had no hardware
to support phone functions as the international version did.

The GSM mode only makes it so you can force the Device into 2g or Edge mode. If you do not want to use LTE just pick WCDMA which is 3g/HSPA+ and GSM(2g/edge). If you are looking to turn off the T-Mobile data part Pull the Sim card out or just put the Tablet into Airplane mode which you can till turn on Wifi. I bought my Note just for Wifi, and using EIP. So i am not using it with T-Mobile Data. getting a data plan on the tablet is a big waste when you can just hotpsot your phone.

Well, it turns out that my tablet is defective. T-Mobile is sending me a replacement. I spoke to several tier 2 techs including one Samsung specialist and they all concurred that the band governing 2g on my Note must be inoperative. Weird right?

Well I got my replacement Note in the mail yesterday and it also will not connect to the 2G/Edge network near my house. I highly doubt I could have gotten 2 bad tablets in a row so there's something else amiss here. Perhaps the specs on T-Mo's website is incorrect and this new device simply doesn't have the capability to go to 2G/Edge or the modem firmware being used is a crippled version.
Very disappointed to say the least; yes Edge is horrendously slow but can be beneficial in a pinch sometimes. Any thoughts?

Yeah, I think you're right; despite unlocking mine and using it on AT&T (which does have better coverage), there's places on my commute where there's 4 bars, yet no data transfer. I've yet to see an "E" or "3G" symbol, either.
I'm thinking about trying to flash the P605M radio, but that'll have to wait 'till the weekend.

Please keep me posted on your results if you do end up flashing the modem. I'd be very interested to see what you discover.
I wonder if this move by T-Mo to cut 2g/Edge compatibility has something to do with their rumored intention of converting all of their 2g spectrum to 4g? Even if that were true though, that precludes using this as an unlocked device in other areas or countries that may only have 2g/3g coverage. What about data roaming?

Well, turns out that I might put that off a little bit later than the weekend- I've since had mine unlocked and as it gets the VZW LTE bands, I'm going to see how well it does on that (VZW drops back to CDMA in non-LTE areas, so I'd be completely without service). VZW LTE is pretty ubiquitous from what I'd seen with my OG Xoom, but if it turns out I lose service on the train in large spots I'll revisit GSM options again.
Besides, I might just flash the radios just to see what happens

[Q] Att Note 4 issues with tmobile network

So I bought an Att note 4 unlocked I bought it knowing I might have internet issues but it was cheap, and I'm having issues with the Internet it works fine its fast(not as fast as it should be) just very bad signal and constantly looses connection and searches for network I checked the apn it's on tmobiles network all looks fine, I'm guessing it might be the band issues but I'm using METROPCS which uses Tmobiles network I had a G3 and G2 pervious to getting the note 4 both where from tmobile and never had a single issue with those I would always get full signal never dropped a call not only that I would get download speeds and upload of over 30mbps now it's taken a dump. Any suggestions? I despise att because I use my network a lot away from home I was averaging 150gb a month on my G3 now it seems that it will be hard to do that with this phone pretty bumped use Netflix a lot watch movies online download games etc. :crying:

I have at&t note 4 too on Tmobile and I'm not able to get AWS tmobile bands. Any way to do this as was done with note2 and 3. Tha ks

I have the same setup
I get wierd download speeds
I average about 3-4 down and 12 - 20 up
On 4g lte
I have tried everything only 2 different apn servers to try
Everything works ...just slow for the most part
It's not a tower issue either...it's like that everywhere
Download should always be faster than upload
Tmobile tech support blames the unlocked at&t phone
Sent from my SAMSUNG-SM-N910A using XDA Free mobile app

I blame the phone never had issues with tmobile phones till I got this att version of the note 4

I would think you can't get too upset if you're using a phone from one carrier on another, right? I mean there ARE differences between the networks and the devices themselves...

AT&T LTE/ 4G issues on the Zenfone 2 (North Americal)

Here is the full cause of the issue after much research (probably an amalgamation of all the information above + some more)
When you pop in your 4G AT&T SIM and give AT&T the new IMEI (SIM1) to update in the database, they cannot 'see' this device as an LTE capable device and cannot activate/provision LTE for this phone, even though the phone supports all the required AT&T LTE Bands.
Arguing with them using logic is futile as even the most technologically adept 'Tech Support' representatives will repetitively claim, ''We can only guarantee LTE service on an AT&T device'' This is why you can only see H+ (HSPA+) on your device.
There are now two ways to proceed: (first make sure your APN settings or correct)
1) Use an older AT&T device (LTE capable), pop your SIM back into this device. Call customer care and ask them to update the IMEI to this older handset. Restart your phone, verify the LTE/4G signal on your notification bar/ confirm with LTE discovery/ (your favourite tool)
Now, take the sim card and re-insert it in your Zenfone 2. You should now see the '4G' icon on your Zenfone.
Note: AT&T will conduct occasional system-wide sweeps to verify if their SIM cards are actually inserted in the device whose IMEI they have registered and if not, they will update the IMEI on their database and you may lose 4G and rollback to HSPA+.
2) WAIT. I've spoken to Asus regarding the issue and this is a known issue to them. I've been told to expect a modem firmware update (no ETA - don't ask me) after which, somehow, this issue should not be a concern and AT&T will be able to provision the Zenfone 2 IMEI as an LTE capable device.
3) Some amazing workaround by a technically adept AT&T representative who can 'force' LTE registration to the device
4) You tell me.

Very informative regarding LTE provisioning on AT&T. In my experience, once they contenders and remove the LTE. a new SIM will need to be used to get back LTE. Even though the account is provisioned for LTE.

AT&T stated they will be offering the ZenFone 2 soon with a contract.

That's crazy! There should be no need for these shenanigans on a GSM carrier. I'm sure the service is leaps better, but I did not have this problem on T-Mobile. I do have a prepaid SIM, so that could make all the difference.

Has to be an issue with certain ZP2's i used an att straightalk sim, and had no issue connecting to LTE at all, i just pop the sim in, searched for networks, registered on att added the straightalk att apns and boom done got full LTE signal on 06610.

Had the same issue with my Nexus 5 originally, a real hassle dealing with support to correct (especially on a corporate account). Currently waiting on ZF2 to arrive, but hoping this is corrected in the latest firmware:
"32. Using HW encode for 4G SKU."
http://www.asus.com/zentalk/forum.php?mod=viewthread&tid=12194&extra=page=1

I am tracking this thread and a related thread and wondering if I need to call AT&T and tell them to delete my ZF2's IMEI. I definitely am only showing H+ symbols and when I did a speed tests, uhm, tests definitely reveal I am not getting LTE speeds. AT&T tried to tell me I am seeing H+ symbol because the ZFT is not an AT&T branded product but I didn't really think this was true. H+ is not the worst of the worst and I really would notice it if I had two phones side by side, but I can live with it more or less if I have to, although yes-I want my LTE back if I can get it - the point is that the ZF2 is capable of LTE and I am very much still on an AT&T contract and honoring my contract on a line that has had LTE for at least 2 years or more now. I just merely bought my own phone this time and needed a new SIM card for it as I had nano on the last one. So-would telling AT&T to lose my IMEI and give me a new SIM put LTE on my ZF2? The APN information matches what is already listed so that is of no use-it seems universal to either H+ or LTE.

They need to have an LTE capable AT&T phone first. Then you can switch sim into the ZF2. Had to use my Lumia 635 imei. Unfortunately, once I swith to a non LTE phone, for example, my nexus 4, their system detects it and removes the LTE profile. So, I have to call them again if I want to get LTE on the ZF2.

I have heard that before-hmmm. I would have needed a nano adapter to put the sim from my previous very LTE capable got LTE all the time Lumia phone first and didn't know that ahead of time. But
I did call them and my guess is I am being lied to that they gave me LTE? I now at least can prove it with speed tests and demand that they fix it but how do they do this is at this point
