I was told when I switched TV contract (and was asked to switch from Virgin Mobile to O2) that the mobile side of things to allow me to keep my old number would be done remotely by yourselves because you are now the same company so that when I receive new O2 SIM card I can just put it in phone and use my old number.
When I receive the SIM card do I just put it in my phone and my old number will work automatically?
I have received loads of texts and emails from Virgin and O2 with PAC number and new phone number (which I don't want) and am now thoroughly confused.
Can you give me a straightforward answer please?
