Okay so I have a question for a friend of mine who is on Sprint. He can send a text to me. Then I will send one back, but when he recieves the text, it wont let him send one back to me. It says "invalid address" or something like that. What should he do?
Is he getting an error message that says invalid number? Is he using and epic device? If so this is a know issue where the area code is lost and you can not send to a 7 digit number. This has been addressed in the new update for the epic.
The problem does not occur with every number generally one or two If it is and Epic and he upgrades to gingerbread it will correct the issue until then the only work around is to start a new messages using a 10 digit number
