Plaese dont buy vodafone USB 3G connection. I experienced below problem.
Vodafone took 5 days to activate the connection.
Very slow connection, download capacity is less than 20 Kbps.
simultaneausly they activating 2G as well as 3G for a connection. That leads u to connect GPRS in the day time thru 2G (very slow).
Only night time after 11 PM only its connecting with 3G and speed would be fast.
More over you dont have option to check you usage in post paid connection. Since 3G connection is very costly.charge 2 ps/10kbs.
Planning to surrender the connection .
Thanks & Regards,
Anand
