T-Mobile chat/rcs options not available

Thats the only thing I can think of that would cause my S21 to lose rcs and volte when I have a t-mobile sim in it. It is a sprint phone, it comes with a sprint sim pre installed when you get it.

Im going to hold out with officially switching to t-mobile until I don't have choice. Mainly because I have a killer unlimited everything plan that is $55 a month.
I'm surprised they let you use the sprint sim , they trying phase that out , with t-mobile sim does it change to TMobile start up screen?

I think the plan is integrating the sprint customers and towers over the next 2 years. Then completely dissolve sprint and just have t-mobile. With a t-mobile sim it does change to a t-mobile splash screen on start and installs all the t-mobile bloat.

If they don't try earlier to do that lol. If you ever put your t-mobile sim back try clearing the samsung message data then force stop and see if u get rcs .

I actually put the t-mobile sim in the phone before I even turned it on for the first time. During the setup process it was activated on t-mobiles network. The first one I had I only used on the sprint network and that's how I know that rcs works with out issue on sprint.

Yeah not sure how TMobile handling this on a sprint phone , but sprint sim would get you rcs on unlocked or carrier version .

I was able to figure out what the whole dam issue was with the t-mobile sim. It turns out that when you swap a t-mobile sim into a sprint phone, someone has to go in and manually disable sprint services on your line. Otherwise the phone will be trying to use sprint services while the t-mobile sim is in the device. Apparently in all the time I had a t-mobile sim in my sprint phones no one actually did this 5 minutes worth of work. This causes all sorts of issues, when I had the sim back in my iPhone. It would do everything but receive calls, on the samsung it prevented me from using rcs, volte and pulling updates to the phone.

Now I can not worry about sprints crap network, I always had issues with sms using their network. That was the main reason why I stuck with iPhone for so long. Now that I don't have to worry about that and the fact that sprints network is probably going to get worse as the networks are integrated. I can finally be a happy camper and have android for good!

Oh wow , this a good tip, you called Tmobile to do on their end ? Or you can do this just in settings of the phone?

They have to do it for you, which is where the issue starts. When I activated the sim I just did it online when I activated the phone. The system is suppose to maybe do this automatically but that was not the case for my account.

I see , thank you for updating us .
 
But this isn't an unlocked phone, I bought it directly from sprint which is now owned by t-mobile. I wonder if the t-mobile system registers the device as an unlocked phone when you bring it over from sprints service. That would be why the chat features are not available on a phone purchased through a sprint account and used on t-mobiles network.
RCS works fine for my S21 that I brought from Sprint to T-Mobile.
 
Just picked up a TMO 21 and both stock and Google app worked out of the box no issues. Only problem is most friends have Apple devices
