I have an Iphone 3G

[Anonymous]

I have an IPhone 3g (one of the first ones) and have acquired an Iphone 4s from E-bay which I'm reliably informed is unlocked. Unfortunately the sim card must be smaller as my present sim card cannot be inserted into the phone. What's the best way to convert my old phone to the new one please? Thanks from Harvey

You will need a micro sim which you can get in any O2 store then you will need to do a sim swap which will transfer your number & tariff across to the new sim. They can do this instore for you or you can do it yourself online

Be aware though that the swap can take anything from a few minutes to 24 hours to complete. Reboot your phone every so often to see if you get signal

Your old sim wont fit. The 4S needs a microsim which you can pick up from any O2 store or online...

How reliable is the guarantee the phone is unlocked? as if it's not after you do the sim swap you could be left with sim that won't fit into the old phone until you do another sim swap!!

The micro sim will fit. The best way to find out if it's unlocked will be to pick up another networks payg sim then plug into iTunes & that will confirm if it's locked or not

An unlock by official means is guaranteed

Hence why I suggested plugging into iTunes using a different payg sim
