Quick question about SIM unlocked.

[Ynot]

Was looking for an used iphone on the o2 network but see one SIM unlocked.
Stupid question but need to ask, will this work OK with my o2 sim card?
What do I need to do to get it working?

Thanks in advance.

Should work with any network, if it's SIM unlocked.
