3G to 4g

[Anonymous]

Hi on my rolling contract I've got a 3G sim can I change it to a 4g sim and keep the tariff that I'm on

Yes, you can get a 4G sim but unless you have been upgraded to a 4G tariff you won't get 4G. I think most are 4G tariffs now though so you should be OK, otherwise your tariff won't change.
If you need advice on getting a new sim or the swap process, just ask.

Yes but unless your data allowance is for 4g you will still only recieve 3g.
You will have to get a new sim card and perform a sim swap at o2.Co.UK/swapmysim

Yes.

I assume your phone is 4g compatible too.

Yes, any O2 store can do it for you and no need to have a 4G phone if you are just getting ready for the future as you can still use 3G on a 4G sim card.
