If you've been waiting to give LINE's Call service a try, now's your chance -- so long as you live in the right country, anyway. Those using LINE's Android app in Colombia, Japan, Mexico, Peru, the Philippines, Spain, Thailand and the US can dial most any phone number at rates that might well beat what their carriers would offer. Americans get one of the best deals: their calls start at 2 cents per minute using prepaid credit, and they can pay 70 cents per month for an hour's worth of talk time. The Chinese will get a similar bargain when Call reaches them in the near future, and LINE-to-LINE conversations are always free. There's no iOS support yet, but we wouldn't be shocked if the corresponding app update arrives relatively soon.
