[Q] Retail Moto X with Verizon, Internet Working, Texting Working, No Calling topic

I have a retail verizon Moto X that I purchased from a friend. The calling does not work. It says "Mobile Network Not Available". The friend was using it on T-Mobile, I don't know if somehow the radio settings for the phone got internally changed when he did the 4.4.2 update. I've factory reset the phone several times, got a new sim card, trouble shouted with Verizon.

Why is the data and texting working, but the calling is not?!!

Driving me crazy.

Please advise!!!!
