Can I have FIDO switch my microSIM to miniSIM back to (the original) microSIM without any problems?
I always assumed I could re-activate my previous SIM without having to purchase a new one each time.
(I've been offered the chance to test drive a friend's smartphone)

Solved! Go to Solution.
Once the SIM is deactivated, it cannot be reactivated again, you would have to purchase a new one.
Please note that if you have any contacts on the SIM, they will be lost, so it is important that you back everything up before proceeding with the switch.
