COIMBATORE: Dont ever buy 3g from airtel. I activated airtel 3g in my prepaid sim and xperienced very low speed with huawei dongle. I got 70-80kbps speed, but no line drop. first I wondered if I my 3G wasnt activated, so sent a duplicate 3G activation msg. I said "3G services are already active in your mobile".Damn,
I would say VODAFONE: Fast, but expensive, AIRCEL: Good reasonable speed, and Ok ok price(now that dey made it 199/month, its worth awesome), rest no idea
