Flag of the Channel Islands 1

Basics Edit

This article refers to the Channel Islands, an archipelago of British Crown dependencies in the English Channel off the French coast of Normandy. It comprises the two main islands of Jersey and Guernsey. The networks in Jersey and Guernsey are separate, although the same companies now cover both jurisdictions. Guernsey networks cover the smaller inhabited islands of Alderney, Sark, Herm, Jethou and Brecqhou.

The Channel Islands are not part of the United Kingdom, despite being British and geographically close to the United Kingdom. Consequently they are not part of the European Union (EU) or the European Economic Area (EEA), and are therefore not subject to EU roaming price caps, either for visitors from the EU & EEA, or for residents who travel to the EU or EEA.

Providers Edit

All Channel Islands are covered by the same three networks:

  • Sure
  • JT Jersey/Guernsey
  • Airtel-Vodafone

Jersey and Guernsey always operated their own telephone services independently of Britain's national system. Both islands still form part of the British telephone numbering plan, but Ofcom (the UK regulator) doesn't have responsibility for telecommunications regulatory and licensing issues on the islands. This job is done by a local agency called CICRA.

2G is on 900 and 1800 MHz and 3G on 2100 MHz on all three operators. CICRA awarded 4G spectrum in 2014 on 800 and 2600 MHz. All three operators already started in 2015 and give out 4G/LTE to prepaid customers without surcharges on all of their plans. Like in the UK, prepaid is mostly called pay-as-you-go and given out without registration.

EU roaming regulations Edit

The Channel Islands are not part of the UK, nor the EU or EEA, and EU roaming caps don't apply to them. While the local regulator (CICRA) has forced the local networks to apply roaming caps for the benefit of their customers - given that the EU ones do not apply, these would only apply to SIMs issued by those operators used elsewhere, there is nothing forcing the SIM issuers elsewhere to charge lower rates when roaming on the Channel Islands. This leads to a very mixed response of European operators: while most UK-based and Irish providers include the Channel Islands into their EU category, many other European providers don't. Having an EU-issued SIM card on roaming, check with your provider first or disable roaming.

Sure Edit

Sure telecom

Sure is the leading operator on the islands. It became part of Cable & Wireless Communications in 2010 and was purchased by Bahrain-backed Batelco Islands Ltd. in 2013. 4G/LTE started in 2015 and is given out on prepaid without surcharge. It claims to have full 4G/LTE coverage already on both main islands.
