Ported 10 hours ago - not able to send or receive SMS - no error message

Porting was done correctly on my end.

I contacted the porting team later that night - apparently "tech support" and "porting support" are different options in the phone menu...  The issue was that I had no "profile" for RCS [which I had used before on that number] - so messaged to/from my number were going into a black hole.

Porting tech support had me turn off device - they "created a profile" and I turned device on again. Presto - texting now works.
