I can receive text messages from a Sprint Galaxy phone, but when I reply to the text I get this reply: "Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code". HELP!!!

For some reason my iPhone 6 plus can receive text messages from a Sprint Galaxy phone, but when I try to reply to the text I get this error message "Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code". I called At&t and found a work around, which is to use brackets [ , ] , instead of the area code parentheses. BUT this then causes the message thread to appear in two separate boxes on my messages app. Ive never had this problem before and have always been able to text people with sprint phones. Ive tried resetting my phone, deleting the contact and re-saving it.. everything!! How can this be fixed???

iPhone 6 Plus, iOS 8.4, At&t carrier

Delete the contact, reenter it without parentheses.

Deleted the contact and all the messages, then re-entered the number without the parentheses = still the same issue.

Deleted the contact again and all the messages, re-entered the number with parentheses (just for good measure) = still the same issue.

When I receive texts from the number, the number comes up with parentheses. I am able to call the number with no issues. The person who has the Sprint Galaxy phone has done nothing new to their phone or changed anything with the carrier.

Report the problem to your carrier.

Did that and they also gave me a work around, which is to use brackets instead of parentheses.......but now I have two separate message boxes. One for outgoing texts and another for the incoming response texts.

This is either a Sprint or AT&T issue. SMS messages are entirely controlled by the carrier, including the error message you received. The "workaround" is a runaround they're giving you.

I don't know what else to do about this issue. I went to the At&t store and they played with my phone with no luck either. Hopefully this fixes itself on its own, *****!!

Is this the only contact that you are having message issues with? If so, then find out if any of your other friends use Sprint. If not, then it is probably a Sprint issue. If some do, then the issue is down to that particular contact.
