Jersey's mobile network is served by three main operators: Sure Jersey, JT Jersey, and Airtel-Vodafone Jersey. 4G LTE coverage is available across St. Helier and most of the island's populated areas. Jersey is a small island of approximately 116 square kilometres, which means coverage is generally consistent across settled and tourist zones including beaches, coastal roads, and main attractions. Remote cliff path sections and some elevated terrain may have slightly weaker signal in specific locations. Jersey is a Crown dependency with its own telecommunications arrangements separate from the UK mainland and EU. MobiSIM connects through supported local networks to deliver reliable data throughout Jersey's main areas during your visit.
