Iphone 7 Network Unlock

[Marto303]

Do any of you young ( or old ) techy guys know how to unlock an iPhone 7 ?

I bought the phone 2 years ago direct from O2 ( which I assume its locked to ) and would like to use a different network whilst in the UAE in a few weeks time. I have been to a couple of phone places and they can all do it but want £40-£50 to unlock for me which seemed a bit steep 

TIA

Network operator supplied and locked iPhones can only be unlocked by the network operator that supplied it.

Here's the info for O2: https://www.o2.co.uk/help/phones-sims-and-devices/unlocking-an-o2-mobile-to-use-on-a-different-network
