Suggest me the best compatible 3G Dongle for Samsung P3110 tablet?

Hi, recently a deal showcased on homeshop18.com in which this online retailer was selling the samsung galaxy tablet P3110 at a price of just 8,000 approximately. I like the deal and i ordered it but one problem is there i thought that this was a sim supported tablet and thereby i select this one, but it doesn't matter as call can be done via internet also. but i want to know if i want to use 3G for this device i want the best 3G supported dongle as soon as possible.

Please help.;

This tablet is really nice and true value for money. It is compatible with almost all 3G dongle.
