upgraded,do i keep my old sim?

[Anonymous]

Hi.

Ive just upgraded online from a Iphone 4s to a Iphone 5s,its due to arrive tomorrow as i had to take out a new tarriff contract too, will this mean the new tarriff contract will be on the new sim or will it go into my existing sim? Will i need to do the sim swap? Thanks

You will get a new sim as the new iPhone takes a Nano sim rather than a Micro sim.

Call customer services to process the sim swap when you have your new phone ready

Hi

You should get a nano sim with your iPhone.

All you need to do is follow this link to move your new tariff and mobile number to it.

If you don't get one any O2 shop hold them and can do the swap for you. Takes from a few minutes to approx 24 hours to settle. Keep turning airplane mode on and off to help the reconnection.

Ensure you ask for a contract sim as payg ones hold different info on them.

You will need to use the new sim of you want to use 4g anyway.
