iPhone wil not send an RCS message after updating to iOS 18

After iOS 18 was made available, I had downloaded the update on my iPhone 13 Pro Max. I was anticipating trying out the  RCS messaging feature, I discovered right away that it isn’t allowing rcs messages to be sent or received. 

 

    in order to try to resolve the issue I went and searched for solutions. I have tried, restarting the phone, toggling on and off airplane mode, and resetting network settings. NONE of these solutions worked. last thing I did was I checked for a carrier updated and it is up to date. I further checked the IMS status and it shows that only voice and sms is allowed, and RCS is missing. knowing that is under E-SIM, I knew it had to do with T-mobile. 

 

I have called T-Mobile customer care 3 times. the first call, they weren't knowledgeable on the subject of RCS. eventually I was transferred to a "Tech Specialist" that created a trouble ticket. a second call to see If I could get a knowledgeable customer service rep and I was referred to Apple suspecting it was a software problem. Apple refers me back to T-mobile stating that they don't have control over the RCS working on the network and that is the issue of T-Mobile. 

 

    attempt 3 with T-Mobile consisted of deleting my E-SIM and downloading a new one, which did not fix the RCS unavailability fiasco. I was suggested that I do a factory reset or a settings reset but at this point I don't think this the problem. Has anyone experienced this problem? if so have you resolved it? whad did you do? if it is all about IMS allowing RCS, how did you fix that? thanks in advance. 

The same thing is happening to me I’m trying everything I can currently on the line with tmobile and some head Apple guy
