List of UMTS networks

The following is a list of mobile telecommunications networks using third-generation Universal Mobile Telecommunications System (UMTS) technology. This list does not aim to cover all networks, but instead focuses on networks deployed on frequencies other than 2100 MHz which is commonly deployed around the globe and on Multiband deployments.

General information

 * For technical details on UMTS and a list of its designated operating frequencies, bands, and their common names, see UMTS frequency bands.
 * Networks on the global UMTS-bands 1 and 8 are suitable for global roaming in ITU Regions 1, 2 (some countries) and 3.
 * Networks on UMTS-bands 2 and 4 allow roaming in ITU Region 2 (Americas) only.
 * Networks on UMTS band 5 are suitable for roaming in ITU Regions 2 and 3 (single countries).

Europe, Middle East & Africa (EMEA)
Networks in Europe, the Middle East and Africa are exclusively deployed on 2100 MHz (Band 1) and/or 900 MHz (Band 8).

North America, Central America and South America
Networks in this region are commonly deployed on 850 MHz (Band 5) and/or 1900 MHz (Band 2) unless denoted otherwise.
