Why do I keep getting 923-0 messages when trying to text?
I just got my new iphone 5 from Sprint. They transfered all of my info from my previous phone, mostly just my contacts to my new iphone. When trying to text certain people I keep getting this 923-0 error message "Message sent using invalid number of digits. Please resend using 10 digit number or valid short code. Msg 2114." They never receive my text and I keep getting this message. So I tried changing the numbers so they had the area code to fulfull the 10 digit number request, doesn't work. I've deleted the contact completely and entered them in again with area code included, doesn't work. I've gone back into the Sprint store and tried to get them to fix it and they said they can't and that I need to contact apple support. I can't figure out what is going on and why this seems so hard to fix something so easy as a number to text to. iphones to iphones work just fine with the imessage app, but not to other phones. This is driving me crazy. Does anyone know a solution to this problem?
iPhone 5, iOS 6
