Hi. I have a Sony Ericsson K800i that I havenīt used for many years. I am abroad and the orange mobile phone SIM card shows Inactive when I turn on the phone.
I would like to give the phone to a young nephew down here but when he inserts his SIM card it asks: "Insert correct SIM card"
I took the phone to some local mobile phone technitians around here but non of them know how to unlock an old Orange Sony Ericsson K800i.
Any help on this matter?
