error invalid number
From my iPhone or Mac Messages, When I try to send a text message to a valid 10 digit number, I get this message:
"Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code. ¿"
This only happens for a few contacts, not all.I just returned from an overseas trip where I used a UK based sim card and number. Does this have anything to do with it?
