How international roaming works, and why your device matters

• Four frequencies (850/900/1800/1900 MHz) are used for wireless services worldwide. 3G frequencies include: 2100 3G; 1700/2100 3G.
• Each phone has a radio transmitter-receiver that works on one frequency (single-band) or on more than one frequency (multi-band).
• Since frequencies vary from carrier to carrier and country to country, you’ll need a device for international roaming that works on the frequency where you're traveling. If you have a “quad-band” device, it will work virtually anywhere there’s a wireless signal.

To check if your device supports international roaming:

• log in to My T-Mobile for personalized information about your device’s band support, or
• check the features for your device ›

If you're traveling to Canada or Mexico, any T-Mobile phone will work.

• From the phones page , select the “International phone” check box under “Shop by feature,” or if you’re looking at a particular phone, check the Overview section for the bands supported, or
• Choose a phone or device that supports the frequencies used in the countries you're planning to visit.

**Some devices may transmit and receive data without any user action, which may result in unexpected charges when you travel internationally. Some services that are free of charge when used domestically may incur charges when roaming internationally.
