SPH-L720 unlocked for ATT question(s) - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I just successfully flashed the modem/rom/etc on my new S4 for ATT. I have service with H+ on ATT but I am unable to get LTE, GPS, or MMS messages. Does anyone know if there is a way to get these functions working yet on this phone?
4.4.2 Firmware.

Sounds like the apns are messed up. Maybe search for what they should be and verify against what is set on your device.

I have verified the APN is correct per another ATT S4 stock and my old S3 LTE APN, still no LTE. let me remind you that this is a n unlocked SPRINT phone with GSM enabled as primary connection..

Make sure the network mode is set to LTE/WCDMA/GSM or something with LTE if you have other options. Also, i'm not entirely sure the Sprint model has the same LTE bands enabled.

SGH-M919v Videotron to TELUS

Greetings all
Is there a way to get an unlocked SGH M919V from Videotron to work with TELUS , the phone works but not LTE and if I enable it using the enable all LTE in the phone console I lose the capability to make or receive phone calls .
Do I need to install a different firmware and if so which one.
Thanks in advance.

Hi there..
All of you masters out there. I just jumped from an iphone to s4. And got this S4-SGH M919V from WIND Canada.
I am a newbee to Android. Now I have been searching if there is a way to enable LTE in my S4. I am facing the exact same problem as my friend posted above. I have tried enabling LTE through ×#2263# command. It does show an esterik infront of LTE bands once selected butttttt I cant make calls.
Now I think this is happening because Wind model of S4 which I have does not support the LTE band frequencies...
My question is if there anyway I can flash the modem firmware from T-mobile which apparently has all the LTE bands in it????
Will that enable LTE in my S4??
P.S I have not rooted or done anything yet with the phone. Just got it unlocked through Wind mobile.
Phone details are as folows..
Wind S4.
Device name : SGH M919V
Baseband : M919VVLUAMG1.
I am currently using wind mobile sim card with 4g speed on it.
I really need this LTE enabled. Because when I put a Bell sim in my phone. It connects data with 3g. Its not showing LTE at all. And when I tried forcing LTE with bell sim inserted, the LTE works fine but I lose the calls.
I would greately appreciate any guidence here. Thank you.

the answer...
Not sure if anyone still needs the answer to this but i just figured it out WITHOUT having to flash anything to the phone... phone is 100% stock except that its unlocked... Its the SGH-M919V from WIND mobile in Canada.. I switched over to Koodo mobile and LTE wasnt working... So open the dialer and type in *#2263# and hit AUTOMATIC and make sure theres a star beside it... before this only 3G would come up... Now LTE works!!! Good luck!

APN Editing

Hi,
I was thinking about purchasing a verizon Note3 however I read the APN for the data setting was locked out just like the Note 2 was. I am just curious is this true? Was it ever unlocked on the Note 2?

here ya go

Unfortunately, we'll still need root to do this if it is locked out by default on the N3

You cannot change the APN setting with the Verizon SIM in the phone, the menu items are grayed out. However, if you put in a non-Verizon SIM the APN menu becomes accessible and you are able to add a different APN for the network of the new SIM provider.

can anybody please verify this?
also, if you put in another network's SIMCARD in the NOTE3, will you be able to do calls, txt/MMS? or only DATA?
will be traveling international this DEC and would like to be able to put in a local SIMCARD and use it instead of having to pay VERIZON extra for roaming charges..
any help would be greatly appreciated!
TIA

I am writing this with my Verizon note 3 from Ireland using a sim from the "3" network (three.ie). It works for voice, data (3g, no lte), and texts. My phone is rooted, but I don't think that was needed. So, it does work.
There is a little icon stating "non-Verizon sim", but everything works fine.

I own a Verizon Note 3 and currently I have T-mobile SIM inserted and Voice / DATA (H+ no LTE) are working great.
delete vzw apn?
I have a vzw note 3 I just switched to at&t and after much digging was able to find the proper apn for at&t. What I cant figure out is how to delete the old Verizon apn as it's grayed out. Does anyone know how to access this to edit or delete?
Is it bothering you that much?? Not sure who you could delete it but why is it a bother ??

SM-G900i use with AT&T

Hello all, i have a question regarding an Australian Telstra Galaxy S5 with att service. the phone works with voice and text but has no data or mms. i have added an apn from my sim card in a galaxy nexus that gets me edge service. i have found band selection in the service menu but non seem to make it any better. I'm sure LTE won't work but thats ok. as long as i can get 3g at least. do i need to flash say the att s5 modems? if so how? i have the modem file and another already extracted from the att firmware. thanks in advance.
Samsung Galaxy S5 SM-G900i branded telstra
i think firmware ANE1 4.4.2
Rooted
Using a foreign handset on a system will never give you perfect coverage. That is by design, as both Samsung and carriers want to lock you in, not make it easy for you to change carriers. Or do so without buying a new phone.
The specs for your variant suggest that it has full coverage on ATT's 3G bands and partial coverage of their LTE allocations. You don't need an ATT modem, just make sure that your firmware is recent - which it will be by definition, as the S5 was only released a few months ago.
Unfortunately you didn't provide much detail, in particular whether you were roaming or a regular ATT customer. Things that you might check in general, that your phone doesn't blacklist any ATT MCCs (roaming restrictions). That you have the correct APN information and that your ATT SIM is properly provisioned for LTE.
.
Thanks for the reply. I figured it out. In service menu, I was picking compatible gsm bands. Back to network screen in settings, had it on gsm/lte only. That was giving me edge. Read more into wcdma and used network mode wcdma/gsm. That gives me H or H+. I know I won't get lte but with that network mode and another apn, I'm satisfied with the end results.
It sounds like you inadvertently blocked coverage with your previous settings. The default setting is automatic band select which should have worked fine.
Glad you figured it out in the end.
.
Yeah. It was the apn that was hurting me. Default it used the wap.cingular apn. I put my sim in a galaxy nexus and used the apn that gave me. Plus changing network mode. Thanks though!

Anybody with a Verizon S4 on AT&T? mms is not working.

I'm using an unlocked Verizon S4 on AT&T everything seems to work but mms, already called AT&T and added the correct IMEI to my number, still will not work... only small mms will send/receive.
Thanks.
Update
Installing GoldFinger worked perfectly
The phone is CDMA, AT&T uses GSM. Different bands and all that. I would think that's the problem.

Check your APN to see if it is correct for ATT, do a google search for ATT APN and you should be able to find it. If not I can post up some screenshots for you.
If the APN is correct then it "may" be that the Verizon phone cannot receive due to wrong frequency bands?

Make sure the APN is correct, enable band 4, and set phone to GSM
