Error message when texting on 3GS iphone, AT&T question
i am getting a return message stating:
"XXXXXXX Error invalid number. please re-send using a valid 10 digit mobile number or valid short code." where "XXXXXXX" is her 7 digit phone number.
i have been able to get a text through to my wife before (who's on Verizon) with my iPhone. and i have her contact entry setup as a 10 digit mobile phone number. i've texted other friends on AT&T, Sprint & Verizon. as well as others within my area code. so does anyone know why i can't get messages to go through to her?? i'm even on the 3G network when attempting this. or better yet, WiFi.
i had her send me a message just before i posted this, and she can send to my phone no problem. i'm a bit perplexed why her messages i send her are bouncing back to me stating her number is invalid. and what's a "short code"?
