Switching from PAYG SIM to Pay monthly sim

[piggy24]

I have had a PAYG plan with Three for about a year now, but that no longer suited my needs. So I bought a Pay monthly 8GB sim from Three. This SIM card has a new number, and I wondered if I can port my old  number from the old PAYG plan to my new pay monthly plan.

You need to port your Three PAYG number to another network PAYG and then transfer it back unfortunately.
