United Kingdom: Mobile Coverage & Carriers
ESIMBYCOUNTRY at checkout · See all codes →The United Kingdom has four major mobile network operators: EE, O2, Vodafone, and Three. All three radio generations—3G, 4G/LTE, and 5G—are commercially launched across the country. A roaming eSIM in the UK is likely to connect using LTE bands B20 (800 MHz), B3 (1800 MHz), B1 (2100 MHz), and B7 (2600 MHz), with 5G connectivity available on n78 (3.5 GHz) and n28 (700 MHz) where coverage exists.
Local UK carriers issue eSIMs, making it straightforward for travelers and new users to activate service digitally. The combination of established 4G infrastructure and expanding 5G deployment ensures broad coverage options across populated areas and increasingly into regional locations.
