I purchased a Blackberry device from Hutch (now Vodafone),Ansal plaza, new delhi after paying MRP Rs24990. Then i used it for some time and now i want to change my network from Vodafone to Airtel. But, Vodafone have locked it, so that it cant be used with any other network then Vodafone. When i insert the sim of any other mobile network, it says "INVALID SIM".
My point is that when i have paid MRP price of Blackberry device and it is not on discounted price or not with any contact mobile plan, as practiced in western countries,then how can they block my device. In western countries,you can have a Mobile phone as low as one euro and it is condition based, that you have to use the service at least or minimum two years. In that case, they block the handset of given mobile. but here, i am paying MRP and they can not force me to use their services.
As a consumer, i should be free to use it as i want, right?

So,this is to request you to please bring this to notice to Authorities,who can help me out. We all should do something about this. At one or another, at some point of time, we all have to go through this kind or similar kind of problems.

Thanks,
Vijay sen.
