THanks for the heads up, I will just keep swapping the sim card then or get a cloner as I have cloned Sims myself before it just isn't as reliable, thanks for the heads up.

SIM cloning is something that was possible some years back, due to a security flaw in the original SIM design. I understood that it is not possible to clone modern SIMs as the security flaw has been corrected.
