I live in NY, and will be visiting India for 3 weeks. My plan is 500 mins a month or somthing, but I'm not sure if thats only in USA or if that also includes India as well...

and if not, how much will it cost to get a plan for my India trip, and where could I go to do this? And if I just text messaged from India and didn't use my phone would I get charged for that as well ? (i have unlimited texting plan, but am not sure if that applies for outside NA)
