Telecommunications in Guernsey

The telecommunications in Guernsey relate to communication systems in Bailiwick of Guernsey, which is a British Crown Dependency off the coast of Normandy, France.


Guernsey broadband consumers pay lower prices than nations like Bermuda, but higher prices than in the UK or the Isle of Man.[1]

Sure all owns all physical broadband lines in Guernsey and JT obtains services through wholesale agreements.[2] From early 2022, Sure is undertaking a rollout of fibre-optic broadband as part of a States of Guernsey. This is an investment of £37.5 million into the island's infrastructure. Sure's goal is near-complete fibre coverage by end 2026.[3] Despite increasing speeds, Sure's infrastructure falls behind in speeds compared to neighbouring Jersey. The States of Guernsey did not invest heavily in fibre optics like the States of Jersey. As such, Guernsey has average broadband speeds of 36.8 Mbps.[4]

Internet connectivity to the rest of the world is provided by undersea cables linked to Jersey, the UK and France. In 2016, a ship - believed to be the King Arthur owned by Mediterranea di Navigazione - dragging its anchor on the seabed in the English Channel cut the three main internet cables to Jersey and Guersey. As a result, all communications traffic had to travel via cables to France.[5]

Mobile telephones

Guernsey is part of the UK's National Telephone Numbering Plan, which means the island shares the UK's international dialling code +44.[6]

In 2020, Sure retains the majority mobile market share of 55%, compared with 24% for Airtel-Vodafone and 21% for JT, the island's other mobile operators. In 2020, there were 71,622 mobile subscriptions, of which 2,845 were mobile only.[2]

Mobile data prices are lower in Guernsey than other similarly-sized countries, such as Bermuda and Malta, but slightly higher than the major operators in the UK.[7]: 21–2  In 2020, the following mobile usage statistics were recorded: 121.9 million mobile minutes, 27.6 million SMS messages and 5.91 million GB of data used.[2]
