My main phone is a Samsung G600 on O2.
Thanks.

Hi there.
If you are out of contract with your phones, you can call up the sp and ask
for the unlock codes for the handset.
You can do a search on the web for remote unlocking.
You can buy an unlocking clip (dependent on phone model)
or you can unlock the handsets yourself using the supplied cables.
take it to a store where someone can unlock it for you while you wait.
Really up to you which route you want to go.
Easiest by far if you want it quick is remote unlocking...
free option is to do a search online for a tutorial for unlocking with cable
if its possible as all cables are different.
