the 116-11 code problem with texting
Yes, I'm suffering from it too. Messages instantly bounce and I get TWO messages telling me I've used 'invalid number.'
I've followed all the steps proposed, except "delete the contact" because I don't HAVE this number in my contacts-- I'm inputting it directly each time. I've deleted all the emails, unhooked from iCloud, restarted, reset, and still the problem.
