hello,i am travelling to kolkata and i would like to take some temporary internet connection for about a month. probably buying a usb modem is the best idea. can anyone suggest me anything ? my objective would be to daily connect to remote servers for working. i was looking at some of the plans (like reliance, tata) : they mention schemes which depends on amount of downloading done - how is this measured ? if i am connected to remote server or do file transfer or browse emails - do all these count for measuring the amount of download ? since i have an adsl connection at my present location (which gives me unlimited access), i am not quite familiar with these plans. so, any help in this regard would be most welcome. thank you.
