How to transfer my old number to my new sim?
I had a standard SIM card, but got a microsim for my iPhone 4S, so how do I transfer all my data off one sim to another one, so my micro sim will have my old number instead of the one already on the sim.
Added (1). I gotta be possible because I did it once before but I can't remember how, plus my sister transferred her number from a standard sim to a micro sim then to a nano sim.
