I recently changed from giffgaff to o2. To keep my number the same I got in touch with o2 and filled in a form with my sim number, current number and the number i want to keep. On my o2 account it says my old number is back (the one I wanted) however when I message people it seems to still be the unwanted new number. Can anyone help please?
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
