I want to unlock my Sony Ericsson K800i but can't find a code.

Has anyone got a code to unlock it?

I want to use a 3 Sim card on an O2 phone

The code for your mobile is as unique as your fingerprint. No two codes are the same. Your best option is to take your mobile to someone who unlocks phones. It's really cheap, only about £5, to have done.

All SIM unlock codes are tied to the particular device IMEI and are carrier specific. The request for that code would need to be made from the carrier that the phone was originally manufactured for. Each carrier has their own guidelines as far as what requirements have to be met before that code will be given out. This is a free process.
