I have been trying many many many times to get my S4 LTE-A to work on the AT&T Network. I used the device on the SKT network, and had no problem getting LTE-A service. I have been using the BYOD Go Phone plan by AT&T for service while I am staying in the United States. I am able to obtain 3G, and "AT&T 4G" (HSPA+). I have verified that I have the correct APN settings, and my account is provisioned as a LTE Device. AT&T has verified my IMEI number as well. I have even fooled around with the SKT Hidden Menu, but I still cannot get LTE service. I saw someone post a tweet about getting LTE on AT&T, using the B17 LTE band, but for some reason, that one is not accessible on my device on the SKT Hidden Menu. Can anyone help me out? How can I get LTE service on my device? I was told many times that the device should get LTE, but no one at AT&T has any idea why I am not getting LTE. (I am in an area of LTE coverage. )
Thank you so much for your help!

Hey all.. I just got my unlocked G2 to work on my local carrier's 3G. Im from the Philippines which only supports Band I (2100) UMTS. Turned out that my old sim wasn't 3G ready/activated and I wasnt able to connect to the 3G network before. Bought a newer sim, inputted the right APN settings and I was good to go. Now I can browse and access the internet/market on my phone wherever I go.
The G2 is indeed an international device. Thanks for all the help.
I'm an AT&T subscriber with a us based I337. Rooted, stock NC1. I'm currently in Canada, North of Toronto. . My phone seems to significantly prefer roaming on the Rogers network, which gets very poor service in my area. Most of the time, I get a tiny bar of G or E network. Sometimes, the Rogers signal weakens enough that I can get on the Telus network, which is great. My wife (unrooted S4 Active, at&t) is mostly on the bell network, which seems good. I've tried making the Telus apn (found elsewhere on this site), and I cannot change the network setting away from Default Setup in Network Operators. I've tried dialer code *#2263# which results in "RWT selection option is restricted".
Please help - I'd like to either force it onto Telus, or force it off Rogers. How can I do this?
Thanks
Hey guys,
I've spent 2 hours searching, but I can't find any clear or up-to-date information. I have a Verizon Wireless Galaxy S4 (SCH-I545 running VRUFNC5), and I will be switching from Verizon to T-Mobile. I've read that the VZW Galaxy S4 does not have the AWS 1700 band enabled, but then I've read that recent updates have enabled it. So, I'm confused.
Will my phone be able to access ALL T-Mobile bands (3G, 4G, 4G LTE, etc) to fully access T-Mobile's network?
If not, what bands will I be missing? Am I able to flash the radio or modify any settings to activate any particular bands?
Thanks everyone!

The answer to your fist question "Will my phone be able to access ALL T-Mobile bands (3G, 4G, 4G LTE, etc) to fully access T-Mobile's network?":
From a quick glance no, you can see witch version supports what band here:

I was wondering if anyone has successfully flashed an AT&T rom to another carriers device, specifically a Verizon galaxy s4. I was told to try it but I wanted to know if it's been done before.
Is the bootloader on your s4 unlocked?

No it is not.
That's good. However, flashing an i337 ROM onto your phone may result in a hard brick. I don't know about the partition layouts on i337 vs version s4.
With an s3, cross-flashing custom ROMs from an international s3 to a North American s3 will hard brick the North American s3.

I think mine is an international version. How would confirm if it is or not?
Is the Verizon s4 a cdma phone with an 3g/LTE sim slot? Flashing an AT&T ROM to your phone may disable phone calls and data as the AT&T ROM requires a specific bootloader and radio frequencies to work. It could also hard brick the phone.
If I were in your position, I would find out how to flash a custom ROM before attempting to flash the AT&T ROM.
Any particular reason you want/need the AT&T ROM?

My phone has CDMA and GSM network settings. I am using this phone on AT&T because I cannot afford to buy a new one right now. Everything works except sending sms on a LTE signal. Fails every time. If I switch to HSPA+ I can send sms but being on this signal causes my battery to drain really quickly for some reason. So I'm trying to sms to work properly on a LTE signal. Someone suggested I try flashing a AT&T rom to my phone since it would most likely have the correct sms files which he believes is why sms doesn't work properly while on a LTE signal.
I understand. Are the APN settings the same for 3g and LTE?

Yes they are
I did a quick search and found this:
Does your mobile web work? mms uses mobile data and standard text messages do not. I have had mobile data take up to 2 days to work on a new activation you stated you took the apn settings off the att site but I just thought I would post what is on my phone just in case it may be different

both standard and roaming protacols are ipv4
everything else is not set also try turning mobile data off then back on.
also make sure that the phone is in global mode

Yeah everything works except send sms. I can receive sms all day but it fails to send. I can send and receive mms, make and receive calls and browse the web. It's just send a standard text message fails every time. Those are the same APN settings I have currently. And it's not a new activation. I've been trying to figure out a solution to this for about a month.
international version has better roms than any other carrier ....... am using an s4 att version with international carhdrom 4.4.2

The reason it isn't working on LTE is because the Verizon S4 only supports 2 LTE bands and does not have all the LTE bands needed for the AT&T network. There is no way for you to use the LTE network fully and get SMS to work. This is a hardware limitation.
US GSM (AT&T - Model: SGH-I337):
GSM/EDGE: 850/900/1900/1800 MHz
UMTS/HSPA+: 850/1900/2100 MHz
LTE: 700/850/1700/2100/2600 MHz
US CDMA (Verizon - Model: SCH-I545)
CDMA EV-DO Rev. A and Rev. B: 800/1900 MHz
GSM/EDGE: 850/900/1800/1900 MHz
UMTS/HSPA+: 850/900/1900/2100
LTE: 700/1700 MHz (Bands 4, 13)
I have not personally needed to do this, but you can modify your "SMSC" preferred network type from "LTE/GSM" to "GSM Auto" which should route all your SMS messages through HSPA+ instead of LTE. Therefore, you can use your phone on LTE (calls/data) like normal but the SMS will be HSPA+.
Root device if you arent.
Install Advanced Signal Status
Hit "Additional Info" in the app and then "Phone information".
Change dropdown for "Set preferred network type:" to "GSM Auto".
You can hit "Refresh" button and it should show "+13123149810" for AT&T otherwise change it to that for AT&T.
Restart phone.
Hopefully that works!

Actually I can activate all the LTE bands through one of the hidden menus. But when I do it still doesn't work.

That is because the Verizon S4 itself, hardware wise, does not support all the bands AT&T uses (like band 17). There is nothing you can do to make your phone work on network frequencies that your device doesn't support, no software can change that.
Sorry.

But in the service menu I have it shows all those bands and gives me the option in which ones to activate
First you need to make sure your APN settings are correct.
With my service I had to change that APN to tracphone.vzwentp and that got my 3G service.
After that Dial *#*#4636#*#* for phone testing
Go into * Phone information *
Then down to * Set preferred network type * and set it to * LTE/CDMA auto (PRL) *
This helped give me 4G LTE
And or you need to change the preferred network under cellular network settings to LTE/CDMA
First post so let me know if I need to change anything thanks
So apparently when I changed the band over to USA Band it gave me LTE. The calling worked for around two days and then just stopped working but I still had LTE.
Once I changed the Band back over to Cellular it gave me calling and txt back. I can switch it back and forth to get either 3G or 4G.
I'm hoping that with the new Nougat update it will fix this issue but for now if your calling and LTE work for you on USA Band more power too you.
If the Nougat update doesn't fix this issue I'm going back to Straight Talk AT&T where I had 4G LTE, Talk, and TXT

What 4g speeds are you getting? Hear Verizon mvno are capped at 5mbps

I only get 5.4mbps down and 2.3mbps up so far.
I'm headed to California in two weeks where I wanted to test it.
Before when I was a Verizon customer I got 65mbps down so I'll see if it's different there too.
It's possible it is throttled. I have Net10 and using the CDMA option because Verizon has awesome signal where I live compared to att. Att did have higher speed rates on LTE but 5mpbs is more than enough for what I need and what anyone should need.
All Verizon MVNOs are throttled to ~5Mbps down, ~2Mbps up. Only Verizon Prepaid proper and Verizon Postpaid are unthrottled.
Hi there, your guide helped me get on LTE. Thank you!
United States band option is located in the 3 dots in the upper right hand corner.
So why in the world is it that these MVNOs recognize this phone straight away using the verizon network, but through VZW I can only get 3G? This is infuriating! I set up several of these for friends on prepaid networks and they all worked straight away with 4G. Finally added our son to our VZW plan so he could use his phone as an actual phone and it's stuck in 3G hell.
I'm on an MNVO using Verizon's network and it defaulted to 3G. I had to do this to get on 4G. I've lost the ability to make phone calls though, so I'm using hangouts for that function.
I can confirm that regular calling does not function on 4G LTE so like the OP, I am having to switch back and forth on Automatic and United States which is aggrivating.
I hope this helps someone:
I have LineageOS 14 nightly installed on this phone. I was going to return it because I was tired of dealing with the switch to make calls.
I figured out that my baseband wasn't the latest, so I figured one final nuclear option of flashing the stock back on to the device would potentially help this.
After a long bout with a soft bricked phone, I managed to get the phone to flash back to stock Amazon adz and then take an OTA. My baseband changed from x45R to x62R.
I then reflashed TWRP and LineageOS 14. It still didn't work but I played around with the settings and managed to get it working. You have to set the Radio Band to Automatic and then you'll get LTE data and CDMA voice. Preferred network type in Mobile network settings is LTE / CDMA. FYI The settings may reset after a reboot.
