I' using a galaxy A5 2017 and all was fine until I got a new number. My problem is when I send a chat message it is being received from my old number and not my new 1. I have tried turning advanced messaging off then on but still the same. Can anyone help me out as in what I need to do
Was your number transferred from one network to another with a PAC @Kieran2604? Also are you able to edit the number stored in your settings? Go to Settings > About phone > My phone number and see if you're able to edit the number.
