5G sim

[Belaztruck256B]

Hi, I have never had 5G on this phone and a repair shop said it is because I don’t have a 5G sim?

My phone is an iPhone 13 mini

Pop into your local O2 store with photo ID or call customer services.
You can use Skype to call if no other phone.

When it comes to the reason you are calling, stay silent for 15 seconds and you will be taken to the keypad options.

Your best bet is to visit your local o2 store with some photo ID and ask for a new sim then @Belaztruck256B 

You can walk away with one then.

Or call customer services, but your existing sim will be disconnected and you will need to wait for a new one to arrive in the post...
