I'm already a member but is it possible to have a 2nd Sim / number or do I need to use a different email address to set up,I have tried but get a message saying that I'm already a member do I need to change my Sim?
If you want a second 48 SIM then you need to get a new separate one and set it up as a new account with a different email address etc. A single 48 account cannot support more than one SIM.
