Error sending an SMS text to another phone.
I receive an automated text error message: "5978609 Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code."
The number is correct and in the 10 digit format.
I had the phone text me (which I get just fine), but when I reply to that message I get same error!
What is going on? How do I get this fixed?
iPhone 5s, iOS 8.4
