Hi

l will be recieving my iphone 4S soon ,at the moment l have the 3GS. The guy on the phone from Orange says l can simply take the Sim from the 3GS and put it into the 4S, however l have been told this is impossible due to different Sim sizes.
Could anyone explain to me please what l will have to do when the new phone arrives , it will be an extension of current contract (keeping same number etc).
Thanks in advance ,not too well up on these matters ,hoping someone can help

He is talking BS! The 4S will use a micro-SIM. You can either cut your current one down to size with a tool from Ebay or similar. But easier is to ask Orange to send you a micro-SIM with your details on!

I'm not with Orange but they may send you a MicroSIM in the box?

Then you would have to contact Customer Services to activate the new SIM and take the old one off line.

As the other poster says, the SIM from your 3G(S) will not work in the 4S.

Thanks to you both for your answers, will give orange a ring in the morning and see whats happening.
