Hi,I'm not an Indian citizen. I'm coming from abroad to live in Chennai on my gap year for about 6-8 months.I heard Airtel has the best 3g coverage in India. I was wondering if Airtel is the best network for Chennai and Tamil Nadu for using 3g on my phone?I normally go through about 2gb of data where I live. So can I get a similar plan in India?Also what's better and safer, postpaid or prepaid?I've read and heard stuff about people with prepaid waking up to find random things they didn't request being charged to their phone, does this happen on postpaid?Also what is the cheapest way to make calls within my own network?And why is it so hard to get a sim card in India? So many documents... -.- Sent from my HTC Desire using Tapatalk
