My SIM card won’t work in another unlocked phone?

[Rs5]

Hi, I’ve recently bought an unlocked iPhone 8 Plus as my currently phone is faulty. When changing my sim over to the new phone it doesn’t seem to be working? I’m on a pay monthly sim only?

My partner tried his Vodafone sim and another Giffgaff sim in the new phone and they seem to be working fine.

Any help would be greatly appreciated

Thanks

You probably need to contact customer services and ask them to enable iData on your account/or you need a new sim Guide: How to find help & contact O2

When you say it isn't working, what do you mean?
Do you get an error message like sim not provisioned, or enter sim unlock code?
Or can you just not use data or make calls?

It must be unlocked as the Vodafone SIM works, so more info needed as requested please.

Hi,

When I put my sim in it says Sim not supported.
