I have an Apple 6s plus and started noticing a few months ago that my phone does not recognize certain cell numbers and will list them like this: (812)?555-1212. the question mark is inside of a black diamond. I can still text them, but when they reply it will show up as a recognized contact. My original text goes out unknown with the "?", but their response comes back on another text message or on the text conversation that I sent mine out on.
Has anyone else experienced that and been able to fix it? Apple support was unable to solve the issue.
Backing up did not help using the oldest version that I had available.
Not a huge deal, but it is frustrating.
Any suggestions?
