Does BSNL 3G Comes Bundled with a Locked Data Card?

[rome9t9]

I am thinking of buying BSNL 3G and can't find a reliable seller in my city who sells genuine Huawei data cards. So I am going ahead and buying the BSNL 3G sim alongwith their bundled data card.Now if in case I don't like BSNL 3G I would want to change to other operators and for that I don't want to buy another data card.I am wondering if the datacard bundled alongwith BSNL 3g connection can be used with other 3g sim cards(docomo, airtel 3g etc)?
