Can i unlock a Nokia 2680 slide for free?

[Me not you.]

Hi, I've just bought my mum a new phone but it comes locked to Vodafone. She uses 02 and doesn't want to change to another provider. Can i unlock this phone either for free or on the cheap?
I've looked on the web but there are a lot of forums regarding this issue and i can't find one that directly relates. Also a lot of sites say they can do it but then they want £15 - 25.
Any help will be greatly appreciated.

Thanks.

To unlock mobile phones codes are the best way , because it is easy and safe for your mobile, but at a free of cost is not possible so do not worry about this one, you can get a code at a reasonable cost itself,
