I have got my son a new phone for Xmas. His current phone takes a normal size sim, the new phone takes a micro sim.
I have ordered a new sim from orange which is a normal size with a micro sim within it.
Now assuming the people at orange won't be working Xmas morning, should I put the new sim in his current phone (he knows he's getting a new phone for Xmas, just doesn't know what) and phone orange now and get the new sim working?
The new phone is unlocked for any network , so am correct in thinking I can just insert new sim in new phone and all will be fine and dandy if I've activated the sim in the old phone before Xmas?
Hope that makes sense!
