Digits SMS from MVNO

ACTUALIZACIÓN: In my many searches I skimmed something that suggested this issue may be caused by a SIM card that was not properly provisioned. 

I recalled that when my DATA with PAIRED DIGITS line was originally set up the agent mistakenly set it up as a DIGITS TALK AND TEXT. I called Tmobile and an agent corrected it. I figured maybe when it was switched over something was not done correctly. I figured its worth a shot. I called Tmobile and told them I was having an issue with my SIM card and asked for a replacement SIM.

VIOLA!

Everything now works almost as it should. I do need to turn off imessage. Imessage sometimes tells me message not sent when I send a message to another Iphone even though it was sent. (I suspect I message is using the phantom phone number to confirm it was received and it is being sent through the digits main line so imessage does not put the 2 together.

all in in all, it works.
