From my experience once you got it from a network shop, it is locked even if it is sim free.

My previous XZ premium was from EE shop and it only works on EE. So you may need to get it unlocked.

yes it looks unlocked but when you buy a phone from a network shop the features are being limited to that network as they install an adapted version of android on the phone.

I got the phone at Carphone warehouse with a new O2 contract and I don't see this option anywhere 😕

I even had it on my Maze Alpha that I got from China a few years ago (that had a similar design to what Sony is doing now with the Xperia 10, only in 16:9) with Three. So I'm surprised I can't use it on my Xperia 1...
