I have the stock International unlocked SM-G900F, but I want to change my "model" variant to Verizon, which is basically just editing the two build.prop lines ro.product.device and ro.product.name to kltevzw i believe. My basic goal of this mod is to change the LTE notification icon and the NFC icon, I don't really care about the rest.
Now, my question is, does this in any way change frequencies or anything else that can give me (as a non-verizon user living in Switzerland) worse cell reception?

I cant find a clear answer if an ATT galaxy s5 will work on tmobile ( phone is unlocked) or will it be missing some features
and also if I install a tmobile stock rom on att phone will it have the wifi calling and all the features of a t mobile phone?
im trying to buy a phone today and cant find any solid info on the internet its a bit confusing
There are lots of existing threads that ask and answer this, so your search missed those (or you didn't search).
Anyway, you can use a TMB phone on ATT without any issues. It doesn't work as well in the reverse as you want to do. The ATT model is missing several frequency bands that the TMB phone has. And ATT, unlike most carriers, also locks the bootloader.
So a (SIM unlocked) 900A phone will work on TMB but will have some gaps in coverage. In a large city with lots of redundant bands that may not be much of a problem. But you will be subject to more congestion, dropped calls and outside of large, urban centers you may even have no coverage i.e. if an area is only served by the bands your phone doesn't have.
And the locked bootloader means that you can't install a custom kernel or recovery. Although you can emulate them with the Safestrap program on an ATT handset. The best way to get the TMB apps, wifi calling, etc is to root and install a custom ROM that is 900T based or 900F based, with the TMB apps added.

Hello, I'm new to all this (iPhone convert)
I have recently got my hands on a beautiful galaxy s5, I believe it is a verzion 4g LTE, now the problem is, I am currently based in the UK on the network three (who supports unlimited 3g/4g)
I have set up my phone to work from the network but I am only currently receiving "H & H+"
I believe this isn't 4g?
I have tried to troubleshoot from basic settings and have tried the "advanced signal strength" fix, still no luck unfortunately.
Is there any possible way I can load a custom ROM to make the phone think it isn't verzion or anything along them lines?
Thanks in advanced.
From what I've read, it sounds like you might need to change the CSC to a UK (Three) CSC

EDIT - And yes, it will say 4G once you are connected to 4G
It's running lollipop oc1 and I have flash fire...
It is possible to change the phone to GSM from CDMA, but you have to be on a stock ROM and you have to have a service menu which can be accessed by the dialer. I don't believe the Verizon version has the service menus however as Verizon removed them. If I'm correct about that, there is no way to change the phone to GSM, which you need for T-Mobile. Even if you can do it, it's highly unlikely you would get LTE as the Verizon phone doesn't use and doesn't have the T-Mobile LTE frequencies.
Good evening!
I recently purchased the VZW S7. My immediate plan is to root it and then enable the Samsung carrier info (which VZW disables) so I can get to the engineering screens to check out LTE/network connection information.
I have been searching all over XDA for some type of answer to my question and haven't found it yet. What I can gather is the VZW variant has all the hardware requirements to have every band from every major carrier in the US, however VZW has disabled specific bands in their firmware. This lead me to thinking I will push the 930U firmware to it which, from what I have read here, unlocks all the specific bands as dictated by the SIM card currently inserted into the phone.
Here is my question: with the 930U firmware, how complicated is it to switch carriers on-the-fly, and to have all the bands a particular carrier utilizes?
My main line is VZW, but I also have a T-Mobile line on my Nexus 6P. However, there is zero engineering mode on the 6P, so I am unable to see information like current band, bandwidth, carrier aggregation status, etc. SignalCheck Pro only tells me the band.
So if I want to use the S7 on Verizon and then swap my T-Mobile SIM card in, how does the phone handle this, and it is a hassle once I put my VZW SIM back in?
I hope all this made sense. Essentially what I am wondering is if switching carriers on the fly is as easy as it is on the 6P- just pop the card in and go, with all the necessary LTE bands enabled.
Thank you for your time!
Hello, a quick question.
I am trying to enable volte on Proximus, a Belgian network. I installed a rom that supports VOLTE, Alexndr's rom with PHN CSC.
But I don't see the volte option in Network Additional Settings. Am i missing something? Is there a way to force activate it?
Also, my provider says that they have enabled it only for the s7 for the moment. How can a network recognise a phone type? Via IMEI? And how can I make my phone pass from a g935f?
Thanks!
Many providers aren’t enabling advanced LTE options on older devices due to the hardware they use vs the stuff in the newer phones (such as the S7). That’s one of the downfalls of LTE (Long Term Evolution) or any aging cell technology really. If your Belgian carrier is only supporting the transceiver tech on the S7 and beyond, then youre kinda boned unless they dump a ton of money into upgrading their towers. We have the same issue here in the states with some carriers. Sounds like youre out of luck.
And yes, that’s even if your ROM supports VOLTE since the issue is hardware related
