I purchased Vodafone 3G data card 2 months ago along with my laptop for 1599 Rupees. after purchasing the data card, I came to know that it is locked, which means only Vodafone SIM Card can be used. The place where I am living is somewhat outskirts of the city, so the signal is improper.
Reliability is very poor. Once, I was making Online Transaction, and suddenly it failed, had to wait for 6 days to refund my money back. data Tariffs are also very high! Customer service centres also not responding properly.
