Is wifi calling a part of the rom or a part of the firmware? I am on Tmobile and also want to know if I will lose access to any of the tmobile bands by switching to .17
You won't have any better or worse service, but you will lose wifi calling as well as voLTE.

I have a T-Mobile GN2, and have both TMO and AT&T sim cards. Right now when I plug in the AT&T sim card, I get 4G signals.
Since both devices are identical (based on a 3rd party site), can we install the AT&T rom in an unlocked and rooted TMO GN2, and thereby enabling the LTE functionality??
Or will such attempt brick the phone??
What data plan do you have with your ATT sim? You need a LTE sim and an LTE enable data plan with the APN on the phone before even testing to see if LTE works out of the box. Im wondering the same about the status of the LTE radio on the TMO Note 2. Let me know if you find out anything new.
Hi, my wife just bought this phone for me unlocked, and didnt realize that it wouldnt have t-mobile's wifi calling on it. If I put a tmo rom on the phone should wifi calling work?
It should. Pretty sure its just a carrier restriction on At&t
I want to buy the G4 to use on ATT.
Is it possible to buy a model that is unlocked and unbloated to use on ATT? It must work with the LTE bands. Does the international version work?
If ATT introduces WiFi calling as promised this year, will I not benefit if not using the ATT model? How is WiFi calling supposed to work?
The International model will work and supports all AT&T bands, minus one, Band 30. Band 30 is the newest one and is supposed to go live this summer.
I don't think WiFi calling will work but I'm not positive on that.
I'm looking to bring an unlocked AT&T Note 5 over to use on VZ.
Is it possible to flash VZ firmware and have the phone work just as if it was a VZ to begin with (and receive 3g data, text, and calls) or is that something that's hardware related and flashing the new firmware won't help?
I've found this information, so I know the consequences of using an AT&T phone on VZ normally...
"If you're hoping to use your unlocked AT&T phone on T-Mobile, you should have no problems. Both carriers run their networks on GSM technology, so once your phone is unlocked, just pop in your new T-Mobile SIM card and you'll be up and running. AT&T and T-Mobile both use Band 4 for their LTE service, so 4G LTE devices should be able to access the network without issue.
Although Verizon uses the CDMA standard and not GSM, you still may be able to use your AT&T 4G LTE device on Verizon's LTE network, as they both run on the same spectrum; so LTE data should, theoretically, work fine. However, it's unlikely that you will be able to make or receive calls and texts, or access data over Verizon's 3G service.
Sprint is also a CDMA carrier, but runs its LTE network on a different band of spectrum than T-Mobile, AT&T and Verizon; it may accept selected AT&T devices on its plans, but you'll need to check first."
I'm curious, because I rooted an flashed the unlocked software on a friends VZ's s7 for use on Republic wireless, so I know this sort of thing can be done. I'm just not knowledgeable about the differences in these 2 scenarios.
Thanks so much in advance!
You can't flash any firmware on the AT&T note 5 other than official AT&T note 5 firmware because the bootloader is locked. I'm not sure about the part of using this Note 5 on Verizon.

Not sure what's going on with your Wi-Fi dropping connections but losing mobile data on/during a call is normal with 1 modem (such as our devices) with mobile data (not talking about Wi-Fi data). My old Note 2 was the last device I had with separate modems for calls and data (so they both worked at the same time, calls with mobile data). Nowadays they save money and only provide modem on most modern devices (it sucks I agree). Unless youre using VoIP with WiFi you will always lose mobile data (not talking about Wi-Fi, calls should not interrupt Wi-Fi connections so thats a mystery).
One note, be careful with flashing T-Mobile firmwares to other device flavors, this may cause issues with your device as I believe they use specific certs for the (TMob only). I dont have TMobile so I could be wrong, but I am petty sure the TMob firmware is different than all other flavors.
That is normal. Unfortunately VoLTE is very arbitrary and will not work even on unlocked phones from other carriers. Those phones are setup so that VoLTE works just on their network. You lose data because your phone has to fall back to 3G and UMTS to make or receive a phone call. Also, the G710VM from Verizon lacks LTE band 12 even though the hardware supports it. T-Mobile uses LTE bands 2, 4, and 12. Your best bet is to flash the G710ULM USA Unlocked firmware KDZ via patched LGUP using "Partition DL" mode then "Refurbish" mode once again. That will give you VoLTE calling support AND LTE band 12 support. LG's USA unlocked phones luckily always have VoLTE support on USA carriers.
