Go abroad on the network card can be understood as a phone card, and you use the mobile\/Unicom\/telecom phone card in the country, not only can surf the Internet, but also make phone calls, etc., more powerful, and plug in the mobile phone can be used, absolutely no roaming charges (you are in foreign local use ah), at best is international long-distance only.
