Why is RCS not working between my iPhone running iOS 18 and Android?

I am running iOS 18 on my iPhone 14. RCS is enabled but does not work when messaging my Android phone. I have RCS running on my Android phone and works fine between other Android phones. My iPhone is on the Verizon network while my Android is on T-Mobile. I've tried disabling/enabling RCS on my iPhone a number of times as well as rebooting. Any other suggestions?

I have the 15 pro max

Downloaded the ios update and no options for RCS in message settings

I was previous on Android and my carrier O2 supported RCS

But since this update nothing at all

It's one of the reasons that made me chose this phone over another android becuase with the promice of RCS I could message my friends and family

No idea what's gone wrong but I'm very disappointed

I don't know where the fault lies. I can accept Apple might not be responsible and I actually really don't care who is. I just want it to work.


I am on T-Mobile

It doesn't matter what the recipient is on. My actual device will use RCS for a while and then it will stop. This is verified by Settings > About > ESIM Carrier. Tapping that shows what is enabled. It will say RCS when RCS is enabled and just Voice & SMS when it isn't.


Most of this has nothing to do with my situation. Like I've said, my device will not hold on to RCS for very long when it gets it and then it defaults back to SMS. I suppose it could be an issue with T-Mobile. I haven't contacted them so far because their support tends to take a long time to talk to and in my experience, they tend not to know anything.
