    When I send a message in IOS 7.1 (happened in earlier IOS version too) to one particular contact with only a 10-digit phone in the "Contacts" app, I get:

    "Error Invalid Number. Please re-send using a valid 10 digit mobile number...."

    Looking at the number displayed, there is a leading "1" in front of the area code. Where that "1" is coming from, I have no idea. It is not in the contact entry for that person's iphone number.


    I tried to recreate the contact in question but the same error happens.

    I saw several people who had a similar problem with Google searches, but no clear solution.

    Other texts work fine so it clearly does not seem to be a "Settings" issue. I don't do that much texting so possibly this problem is more widespread than I'm aware of.

    Confused....look forward to any potential solutions to this.

    Wow, good idea. Yes, it was on.

    Unfortunately, after turning it off, I got the same error.

    Thanks very much for your reply.
