Issues w/ texts and phone calls after switching phone.

Used my $200 credit for a Moto G Stylus and switched from an unlocked Galaxy s21. Was planning on using for 2 months to get it unlocked.

Have been having issues with texts and calls since however. Calls won't send. Texts are usually ok but sometimes won't send or get received and I have to restart phone. Just swapped sims when I switched.

Any suggestions? Dont know if it's the phone or the service? Never had an issue on my s21.
