RCS Messaging Waiting For Activation

Hello,

I recently switched carriers from Verizon to Xfinity Mobile. I noticed that I haven’t been receiving texts other than iMessages, so I looked into my settings. My RCS Messaging setting is enabled, but has a status of “waiting for activation.” I tried toggling the setting off and on, and also tried restarting my phone, but the status hasn’t changed. Can someone let me know how to troubleshoot this issue?
