Hi guys,I am visiting Ahmadabad in December for two months from Australia. I will be roaming a lot in Gujarat and other states. Can people here advise me on mobile internet/data providers and their plans.I have GPRS capable phone and laptop. Should I choose USB modem or should I choose sim with GPRS activated on it and use it via my mobile?Also, how long it takes to actually getting connection working? Wait period.Appreciate some advise.
