Content: Call the carrier and ask. While you've got them on the phone, you can find out about getting your smartphone "unlocked" to work on other networks, if it isn't already. Although common before, it's no longer necessary to pay someone to unlock your smartphone! In 2014, the Unlocking Consumer Choice and Wireless Competition Act went into effect requiring mobile phone carriers to unlock your phone for free once it's paid off, and your contract has been fulfilled. With an unlocked GSM phone, you can get a SIM card and join networks in Asia. Tip: Don't let your carrier talk you into purchasing or renting a SIM card for your destination country. You'll be able to get one much cheaper once you arrive in Asia. CDMA vs. GSM Phones
Most of the world uses the Global System for Mobile Communications standard, better known as GSM. Europe mandated the standard in 1987 after a consortium, and most countries adopted it.
