i managed to copy the number down. when i went back later, the number under my name had changed back to the usual 10 digit one. I called and texted the 9 digit number and got a strange enough error message both times, but the numbers did work. any idea what the hell thats about?
I was trying to check my voicemail, so scrolled to my own contact and clicked it. instead of it displaying my actual 10 digit number, it was showing a completely unknown 9 digit number under my name.
