1565:. These are typically referred to as multi-band phones. Dual-band phones can cover GSM networks in pairs such as 900 and 1800 MHz frequencies (Europe, Asia, Australia and Brazil) or 850 and 1900 (North America and Brazil). European tri-band phones typically cover the 900, 1800 and 1900 bands giving good coverage in Europe and allowing limited use in North America, while North American tri-band phones utilize 850, 1800 and 1900 for widespread North American service but limited worldwide use. A new addition has been the quad-band phone, also known as a World Phone, supporting at least all four major GSM bands, allowing for global use (excluding non-GSM countries such as Japan, South Korea and as well countries where 2G system was shut down to release frequencies and spectrum for LTE networks like Australia (since 2017), Singapore and Taiwan (since 2018).

Some countries in
Central and South America have allocated spectrum in the 900 MHz and 1800 MHz bands for GSM in addition to the common GSM deployments at 850 MHz and 1900 MHz for ITU-Region 2 (Americas). The result therefore is a mixture of usage in the Americas that requires
