U can activate vodafone GPRS in ur mobile in just 2 stages.
It has plans like Rs 4/day & 98/month.
to have a check, just activate the 1 day pack by dialing-- *444*5#
then u call 2 d customer care & ask for the gprs setting.
save the incoming setting & restart ur phone.
Now u can browse the internet.
After that if u really like it u can go for the monthly plan.
