i text with my girlfriend all of the time. starting monday, she can't receive texts from me. i get them from her still. i reply, but she doesn't receive them. i send them directly using contacts and by entering her 10 digit number but to no avail. now other friends of mine have confirmed they are not receiving my texts either. i am using the newest apple iphone. never had any problems until this monday. ive tried everything recommended on this message board but nothing works. seems like this is a fairly common problem. i need a solution.
