O2 X2 unlock (where should I look?)

teuqram

I hope I am not going to get my head bitten of for posting this query.

I am a new member and I have been searching not only this Forum but the website too for an answer to my question.

I am looking for a PLUP code for an old O2 X2 mobile phone which I have been given.

When I do the search for 'O2', it tells me that it cannot find any post for this. I must be doing something wrong as I cannot imagine I am the only person who has ever looked for an O2 plup code.

Please, point me in the right direction.

I have tried the other unlocking website too, and there is absolutely no mention of the O2 network either.

Many thanks in advance.
