I switched to ID mobile a few weeks ago and wanted to keep my old number (with o2). I used my PAC code etc to change number and after a few days this switched over. Today I have not had signal and my texts have since been sending from the number assigned by ID mobile with my new sim, instead of the number I switched to. When I go into settings it says the ID mobile number as primary and my other number as ‘used a “primary”’ then when I try to click it says ‘Mobile plan no longer available’ and my number in my phone etc has changed back to the one assigned by ID mobile.
I’ve tried restarting my phone etc and do not want to do a factory reset and I needed the number last time to log back into my Apple ID, obviously I will no longe have access to this if I reset and do not have the old sim?
Please help!
