@saziFollow the advice here Guide: Unlocking an O2 phone to use a different SIM card
Edited to ask if you have tried the sim in the phone as you may find it's unlocked and what network were you on before?

how do i unlock my phone so i can put my o2 contact sim in it
If your O2 sim doesn't work, you will need to contact the network who has locked the phone to get an unlock code.
Which network was the phone on before @sazi ?
OnePlus 6 (O2 & Sfr), Z3 Tablet (Three UK), iPhone 8+ (EE)
