I recently registered with ID Mobile, and selected the option to switch after receiving my SIM (this was because I was unable to retrieve my PAC from Sky at the time). I have now received my SIM and wish to port my existing number over from Sky. However, in order to do so, ID Mobile want to send a confirmation text to the new ID Mobile number they sent me with the SIM. Do I have to install the new SIM with the new number in order to log in so I can submit my PAC to keep my old number? That sounds… odd.
