Reference excerpt

Telecommunication services in Jersey comprise Internet, telephone, broadcasting and postal services, which allow islanders to contact people and receive information.

Internet As of 2018, three companies provide fixed-line services to the island -

Jersey Telecom (JT), who operate island's fixed-line network; Sure, whose services are based on wholesale access to JT's infrastructure; and Newtel, who focus on business customers and also use JT's infrastructure. As all services are based on JT's infrastructure, there is limited competition. Nevertheless, islanders enjoy average fixed broadband download speeds which outstrip the UK and other small countries. As of 2021, Jersey has the highest broadband speeds of any country in the world, with an average rate of 274.27 Mbit/s, compared with Liechtenstein, which only had speeds of 211.26 Mbit/s, and the global average of just 9.10 Mbit/s. JT has dominance over the broadband sector, with 68% broadband market share in 2015, however this is declining relative to the competition. In terms of value for money on high-speed internet services, Jersey broadband consumers pay lower prices than nations like Bermuda, but higher prices than in the UK or the Isle of Man, but for lower-speed services islanders pay far lower prices than other small islands (and less than UK consumers).

Internet connectivity to the rest of the world is provided by undersea cables linked to Guernsey, 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.

Mobile telephones Jersey is part of the UK's National Telephone Numbering Plan, which means the island shares the UK's international dialling code +44. 4G license operators in the island are obligated to provide a 2 Mbit/s download speed to 95% of the island population 90% of the time. In 2016, the island had 95% 4G coverage and higher average mobile data speeds than (7 major cities in) the UK. In 2020, JT retains the majority mobile market share of 52%, compared with 24% for Airtel-Vodafone and 23% for Sure, the island's other mobile operators. In 2020, there were 124,262 mobile subscriptions, of which 2,845 were mobile only. Mobile data prices are lower in Jersey than other similarly sized countries, such as Bermuda and Malta, but slightly higher than the major operators in the UK. In 2020, the following mobile usage statistics were recorded: 202.0 million mobile minutes, 48.3 million SMS messages and 9.56 million GB of data used.

Landline telephones Jersey is part of the UK's National Telephone Numbering Plan, which means the island shares the UK's international dialling code +44. Landline telephone numbers have the area code 01534.

Future The Government of Jersey has a telecommunications development strategy called A telecoms strategy for Jersey.

Telephony

Addressing Jersey is incorporated into the UK National Telephone Numbering Plan, using the following area codes:

JT Global (formerly Jersey Telecom): +44 1534 for land-lines +44 7797 for mobiles Sure (Batelco): +44 7700 for mobiles Airtel-Vodafone: +44 7829 for mobiles

Fixed line Fixed PSTN lines in use; approx 57,700 (2009).

Mobile cellular JT Group Limited Sure Airtel-Vodafone With over 120 mobile phone masts, in 2012, spread across its 119 km2 (46 sq mi) area, the island has a phone mast density almost five times that of the United Kingdom as a whole but similar to any urban area.

Worked examples

Example 1 — a first encounter with Telecommunications in Jersey

Start with the simplest possible case. Write down what Telecommunications in Jersey claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Telecommunications in Jersey before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Telecommunications in Jersey ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Telecommunications in Jersey

In research: Telecommunications in Jersey appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Telecommunications in Jersey in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Telecommunications in Jersey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Telecommunications in Jersey, so understanding it makes those chapters shorter.
In everyday life: Look for Telecommunications in Jersey outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
