O2 bands UK

GSM is a second-generation (2G) cellular technology standard and is, therefore, less capable of providing high-speed data as compared to UMTS, which is a third-generation (3G) technology and LTE, which is a fourth-generation (4G) cellular technology.

Britain operates on a GSM network , so if you’re coming from Europe and many other countries, your current mobile will probably work in the UK either as a roaming service or using a UK SIM card.

In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz . In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band. In the United States, regulatory requirements determine which area can use which band.

A number of frequency bands are used for 4G LTE in the UK. There’s the 800MHz band, the 1400MHz / 1.4GHz band, the 1800MHz / 1.8GHz band, the 2100MHz / 2.6GHz band, the 2300MHz / 2.3GHz band, and the 2600MHz / 2.6GHz band. This wasn’t always the case. Originally only three bands were used for 4G in the UK.
