Sim Card Transfer

[Wheelbrace]

I wish to transfer my Sim to a new phone on same pay as you go basis with the same provider. What will be lost from my existing phone when I transfer.? Help appreciated

Anything that was stored on your phone and not the SIM card.

Nothing much as, no doubt, you will copy it over as well. If it's just the directory, you can copy that to the SIM. (If it's a big directory it may need you to copy it in two halves.)
