HI! What is the way to unlock my iPhone7 to use it with sim card outside the UK? I bought it sim free and have used Pay as you go card of yours and now it is locked to another providers?

Hi @Anonymous Follow the information in this guide  https://community.o2.co.uk/t5/Other-Products-and-Services/Unlocking-an-O2-phone-to-use-a-different-SIM-card/ba-p/1014131

Unless you bought it directly from Apple it will lock to the first network used to activate the phone.
You need to make sure you have £15 credit on your sim then follow the process in my guide linked to above.

Thank you for the answers! What happened when I filled the form for unlocking in the O2 website is that they answered me I don't pass their security checks with the information I gave which is my name, my number and the number of my device? It seems impossible to use my phone again! Please, any suggestions and ideas from you people...?

It also needs the answer to the security question on your account.
If you have any problems, give customer services a call to talk through your request http://www.o2.co.uk/contactus
