i am not sure how 3G plans work. but can i recharge them as per my need? i mean... with airtel edge. i pay 100 bucks for a GB of data. if i finish 1GB before 30 days, i cannot renew it instantly for another month right?i had like a scenario where i can recharge for 3G data like i recharge my prepaid. anytime to add more talktime to my phone. i dislike having a billing cycle for data. more people would probably switch to 3G if they have a validity period like system for data as well. charging premium for amount of data for a fixed time period sucks.
