Apologies if this is a dumb question, but I recently took out a SIM only Pay Monthly contract with O2. During the purchase process I gave my PAC code and said I wanted to transfer my old number. I've received my new SIM from O2 and as per the instruction leaflet that came with it, put it into my phone. There was no mention of what to do if you are porting your number. Given that I've already given my PAC code, will it transfer across automatically at some point, or is there something I need to do to get the process moving?
