Sony Xperia arc Sim Network unlock pin

[Anonymous]

Hi does anyone know how I could go about getting a sim network unlock pin for my old phone as I wish to sell it & I can't ever seem to get hold of O2 customer services 😕

Getting the unlock code from O2 is the safest way.

There are other ways of doing it BUT you can easily brick the phone if you dont know what your doing.
