The best cellphones for International Roaming are the quad band GSM phones. CDMA does not have a widespread adoption, is limited to USA and parts of Asia and does not work across the european union at all. Quad-band GSM phones support the 800 MHz, 900 MHz, 1800 MHz and 1900 MHz frequencies and will guarantee the widest possible coverage across different geographies.
While travelling international the cheapest way is to get an unlocked phone and use an international SIM card. Prepaid international SIM cards can be purchased from sites like Telestial or Maxroam. Our selection of the best international quad cellphones is limited to the unlocked phones.
