GSM data card is used for internet.
Many companies like BSNL,Reliance,Airtel,Vodafone etc provides this data card.
Different plans are there according to your needs. If you need this, you can go to the retailer and ask for their plans.
Data card are divided into two categories:

Broadband speed
High speed will not give you give you much speed, but you can take this plan if you don't have much work to do.
There are many plans in this category.
Broadband speed gives us quick access to internet within a click of your mouse.
Broadband plans are little bit costly.But this will worth you. Because, for speed you have to pay more.
