Bought NOKIA 5230 (pay as you go) sim locked in foreign country?

[Nav]

I received my Nokia5230 a few days ago, it was bought in UK and seems to be conected to T-Mobile, even when T-Mobile card is not inserted it still shows T-mobile when i turn on the phone, it was bought with no contratct(Pay as you go), phone still dosen't let me use my sim card in foreign country, says (sim card is invalid), I know their is a code to unlock it i tried once but it didn't work so i'm afraid to try again so it wouldn't hard lock, and to unlock it here it costs basicly the same as the phone it self, any sugestions?
