Make a few chargeable calls and then fill out the form.<BR /><BR />Or ask a friend on O2 to put their sim in the phone , make a few calls and they request the unlock. Assuming their SIM card is the right size or use an adapter lit available from O2 shops.

The IMEI is no longer on O2's database so they can't confirm it exists at the moment.
