Error Invalid Number - 7 digit number prevents future SMS messages

I can't send SMS messages to one of my contacts at all.

my contact had only 7 digits under "Mobile" phone because he was in my area code.

I tried to send a text to him and got this response:

"####### Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code. <my text message>"

The ####### was his 7-digit number from the contact info.

So, I modified the contact info and put in the area code to make it 10-digits. I tried sending another text message, but that had the same exact response (with only 7 digit number).

I cleared the messages for that contact and tried again, same result.

I synch'ed my iPhone and then tried again, same result.

My contact now has the correct 10 digit number, but whenever I try to send a SMS message to him I get the response with the 7-digit number saying Error Invalid Number.

How can I fix this?

Apparently the phone is wrongly remembering the shorter number, so try this. Edit the contact to put back the 7 digit number, but add a NEW phone number with the 10 digit code, and a different label, perhaps a custom label. Try sending an SMS to that new number. If it works, you can just delete the old 7 digit number entry entirely.
