Sims

[TKL]

I am upgrading an iphone 13 pro and an phone 13 Pro to a 15 pro and 15 Pro Max - do I need to order new sims?

Your sims will work fine in the new phones.

Unless you have 5g sims though, you will need to swap to 5g sims to get 5g signal.

If you already can, no need.

You can pop in store with photo ID to get new sim cards or call O2, however, if ordered on the phone, your old sims will be disconnected immediately, so not ideal.

You need new sims only if you haven't replaced them recently and only if you are in a 5G area

Otherwise use your old sims

If you order new sims from customer service they will disconnect your current sims immediately leaving you with no phone until the new sims arrive

Best option by far is to call in your nearest O2 store and they will supply new sims free and swap your numbers over. Take photo ID

Your iPhone 13 was 5g capable so there's a good chance you already have 5g sims anyway, but in store is the best way to swap them if not.
