How much for minutes to call the states on the local cell phones? I'm only there 6 days, but I need to be able to call home and check on kids and husband and also maybe for some local calls. Thought it might be easier to just use my phone, but maybe not? I'm not planning on bring my ipad, so I could just check email from my phone on wifi and use a local phone. What would cost be to buy a phone and say have at least 100 minutes to call home?
