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 added by 1800 MHz (bands 3, 7 and 20). 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. Please note that on the smaller Islands like Sark and Herm, Sure has a better coverage than JT, whereas JT offers better speeds. On some sections of the islands, and the ship route, even tho connection is shown as 4G+, data speeds might be as low as 2/0.01 Mbit or not present at all so if you want to use a map app on the smaller islands, make sure to download the in advance.

EU roaming Edit

No roaming
Be aware that the Channel Islands are not part of the UK, nor the EU or EEA, where from June 2017 new international roaming rules are enforced. So roaming rates on many European SIM cards are not capped or regulated there and can be much higher.

Some providers, mostly from the UK and Ireland, however voluntarily treat the Isle of Man as an EU territory, but others like O2 UK have ceased to do so. Better check your EU/EEA provider first, before use or buy a local SIM card instead.

When roaming in the UK with a SIM card from the Islands, it's important that you turn off your general mobile data as well as data roaming. Because UK networks are also +44, your handset may recognise this as a local network option and could be using data without you knowing, resulting in unexpected bill shock on your return as Channel Islands providers still charge excessively for 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.

Like them, 4G/LTE is given out on prepaid without surcharges. The network name might be shown as Jsy Tel on some phones. JT covers some parts of the ferry route between Jersey and Guernsey, but speeds, even tho shown as 4G+ are slow and random network disconnects are likely.
