Put your sim in another phone an att phone setup wifi calling. Swap Sims back to your byop non stock. Then call att and tell them their system isn't updated right as it will show the byop again tell them they need to update your IMEI in their system it's showing as a device you tried but didnt work. And have them reset the att branded stock phone again as primary imei

Verizon HTC 10 on ATT?

It is my understanding that the Verizon HTC 10 is unlocked for other carriers. So I'm hoping that someone here can tell me if the bands in the phone work well with ATT service.

I have not tested it out personally but I am 99% sure it will work.
I had a Verizon M9 (which is unlocked just as the HTC 10) and gave it to my girlfriend about 2 months ago. I only had to change the APN settings and she gets flawless service.

For the correct APN settings (for any carrier), search google for "*insert carrier* APN settings".

ATT and Tmobile sim cards work i guess, does LTE work too? Is there a way to flash an international firmware and covert it to a real unlocked phone without verizon traces?
Not working! It shows error as soon as I try to activate it

Do at your own risk.
You should be able to s-off, supercid and flash att ruu, converting to 100% at device.

I'm curious if this actually works.
Any update if it worked?

The unlocked ruu would work at the very least. Just need to change mid and Cid and flash the unlocked ruu. No doubt in my mind it would work then.

I use Cricket which is a sub-brand of ATT. I am able to receive decent speeds, but not anything over 8 Mbps due to my plan.
If you are not able to use an AT&T SIM on your Verizon HTC 10, you can always flash the unlocked firmware.
You can follow the instructions here: http://forum.xda-developers.com/verizon-htc-10/how-to/guide-aosp-roms-booting-vzw-10-via-t3487903
Since you will not need to use a Verizon SIM, you can skip the part about deleting the .img files.

I would like to know the answer to this as well. I was considering flashing to the AT&T firmware for VOLTE and Wifi Calling ,but I'm hesitant because I don't know if I would be able to flash back to 100% Unlocked, stock firmware for SM-G930U.

Verizon is sim unlocked you can just put your sim in and go. If you want to get all the benefits of tmobile simple flash the latest tmobile firmware with odin then internet calling video calling and all that will work. Goto the tmobile thread to find the latest firmware.

Tmobile radio on US Cellular S7 Edge?

I got a S7 edge US Cellular branded from Walmart.. It is UNLOCKED. I put in my tmobile sim, I get lte, but, signal strength is low.
Is it possible to flash Tmobile software on this phone? The reason is I am not getting any strong signals (inspite of it supporting all corresponding LTE bands from Tmobile). Has anyone tried?
what options do I have? Any help is appreciated.
Thanks!

US cellular is just G935U I believe. You can just download the tmobile firmware, stick it in Oden and press flash. I suggest you to try flashing only the modem from the T firmware and use 935U firmware for everything else.

I actually just flashed TMO version via Odin, so far, all seems to be working fine. Does the U version support HD voice/ VOLTE/ Wifi calling on tmobile?
If you flash the T-Mobile firmware then yes and if you flash the U firmware then No

Is your US Cellular G935U? I bought a used one/unlocked -not in Walmart though- and it shows G935R4. I guess I will brick my device if I flash the Tmobile firmware. The problem that I have it show 4glte and speeds are amazing, however there are no bars shown. When I get a call, it shows bars and makes the calls with no issues. SMS works great.

It is the same one I got from Walmart. I flashed the T-Mobile firmware and the phone rocks. It's a seamless process if you have some basic knowledge of flashing. I can help you if needed. Please let me know... thanks.

Thanks, I actually flashed the T-Mobile firmware and it worked pretty well. It failed when I tried to use an older version of Odin. Once you used the most recent one, it's flawless and with no issues.

Calling isn't working?

Every Rom I tried on my GALAXY S4, lately my calling hasn't worked at all on any of the Roms, I would open the phone app trying to call Voicemail and nothing happens, it doesn't ring or nothing just a long pause and a single beep?. I tried finding ways online how to fix it but so far no luck :-/, has anyone found a solution to fix it? Because Im actually so lost on what to do about it right now.
This happens when running the latest stock ROM? Phone shows the correct IMEI from the dialler?

Yeah like my texting and data works fine it's just the calling that doesn't work, and I'm just like lost now and ran out of ideas, like when I go in the settings and go under phone info and it shows I'm connected to mobile network and IMEI info is still the same from stock ROM.
I'm stumped. The sim is working since text and data work.
Is the phone being used with the carrier that issued the phone or was the phone purchased outright and unlocked?

It was originally by telus Canada variant, but recently in Canada they made it free to get your phone unlocked under certain conditions, so I called telus and they unlocked it for me to be world wide, because my phone is actually so simaler to the US and European variant, on how they are built so I Flashed TWRP GT-i9505 on it and now so now I'm running XOSP-UNOFFICAL-20180114-JFLTEXX and everything works except calling, right now that's how I'm responding to this thread is by mobile data.
Yes, the sgh-337m (Canadian variant) and GT-i9505 are very similar but the radio bands supported by each model is different. Maybe certain radio bands need to be unlocked or enabled for voice?
You could try this website to check compatibility with a stock i337m ROM: https://willmyphonework.net/
Edit: I just noticed you are in Vancouver. Which carrier is being used with the phone?

I am using Freedom mobile is my current service provider, not the biggest company but they are growing. OK I'll look at that link
Did you modify the radio bands to enable AWS for Freedom? I know they are expanding their LTE network to bring LTE to phones that previously worked on 3g only like the iPhone 6s a1688.
Modify Bands? May you describe what that is and how? Because I didn't modify anything all I did one day was Flashed stock ROM via Odin from SamMobile and ever since them my IMEI hanged or anything
Freedom frequencies aren't supported by the i337m. The freedom version of the s4 is the sgh-m919v.

What how is that possible I get mobile data and texting though? Because even In Stock ROM I'm able to call as well?
So your talking about Sgh-i337m right?
Just want to confirm that calling with a stock rom on freedom doesn't work but data and text does? If yes, that is strange that calling doesn't work.
Does calling work with another carrier?

No I mean when I ran Lollipop from SamMobile calling worked 100% same with texting and data, but calling doesn't work running custom Rom, it works for texting and Data but not calling.
That is strange. The custom ROMs are made for the jflte?

This is a screenshot of my device info and Rom and no its for the gfltexx
I just noticed now but in the screenshot of "mobile network state" that it says "disconnected" now I'm confused. About my phone is GT-I337M is the original model name.
I think it may be a kernel issue. Is the phone running the kernel included with the rom?
I never actually knew the differences were between a Rom and a kernel? For a while ithought they were the same, hold on I'll take a screenshot of it.
