A Canary Islands trip might be Tenerife with a day on La Gomera, or a loop from Gran Canaria to Fuerteventura and Lanzarote. The islands are Spain and part of the EU, so for an EU SIM nothing changes; for a UK SIM, what you pay depends on the operator, and on the mountain roads around Teide even a good connection can drop.
This guide covers eSIM and roaming in the Canary Islands: who pays what, hopping between islands by ferry or short flight, coverage on the mountain roads, the plan options if your SIM is from outside the EU's roaming area, and who to call.
Key facts for the Canary Islands
- EU roaming: covered by Roam Like at Home, as on the Spanish mainland
- UK SIMs: not covered by EU roaming rules since 2021; each UK operator sets its own terms
- One plan for every island: a Spain plan covers the Canary Islands, which are part of Spain
- Local networks: Movistar, Orange, Vodafone (depending on the plan)
- Emergency numbers: 112 for all emergencies; National Police 091, Guardia Civil 062
EU and UK SIMs in the Canary Islands
The Canary Islands are part of Spain and of the EU, so Roam Like at Home applies exactly as on the mainland: an EU SIM works on every island as it does at home.
UK SIMs are a different case. Since 2021 they are not covered by EU roaming rules, and each UK operator sets its own terms, so check what yours charges in Spain before you fly. With a SIM from elsewhere, such as the United States or Latin America, roaming is usually charged separately.
Island hopping by ferry or short flight
The main islands, Tenerife, Gran Canaria, Lanzarote, Fuerteventura, La Palma, La Gomera and El Hierro, are linked by ferries and short flights. On a ferry, phones near the coast use land networks. Further out the signal can fade, and if the ship runs its own mobile network, a phone may switch to it; that network is not covered by EU roaming rules and is billed separately.
Before you sail, turn data roaming off on your home line, and back on ashore if you rely on an EU SIM for data. Download tickets and maps for your arrival before you board.
Teide, La Palma and the mountain roads
Coverage is good in towns and resorts. On mountain roads and in ravines, for example around Teide on Tenerife, the signal can drop, and in the mountains of La Palma it can be patchy too.
Download offline maps before you drive up, and on a hiking trail tell someone your route and when you expect to be back.
Which plan fits your trip
With an EU SIM, you need nothing extra on any island, unless your tariff gives you only a small data allowance outside your own country.
With a SIM from outside the Roam Like at Home area, a Spain plan covers the Canary Islands, which are part of Spain, so one eSIM works on every island and on the mainland. If your trip continues to another country, the Europe plans cover Spain, Canary Islands included, among 38 destinations.
Telcomia's standard plans are data only, with calls through apps such as WhatsApp, and your own SIM stays in the phone for your number. Each plan's details show the Activation line, the duration, the data and whether you can share the connection.
Before you leave
- With a UK SIM, check your operator's terms for Spain.
- Install the eSIM at home on Wi-Fi, and keep it until the trip is over: some eSIMs can be installed only once.
- Make it your mobile data line, with data roaming on for it and off for your home line.
- Download offline maps of each island you will visit.
- Save 112 in your contacts.
Consular protection: who to call in the Canary Islands
- 112 handles all emergencies on every island, and its operators can often help in English and other languages.
- 091 is the National Police and 062 the Guardia Civil.
- Embassies are in Madrid, and many countries also have consulates on the coasts and islands. The Telcomia app shows which mission is responsible for you, with address and phone.
- Emergency phrases in Spanish are ready to show on screen in the app.
Questions travellers ask about the Canary Islands
Does EU roaming work in the Canary Islands?
Yes. The Canary Islands are part of Spain and of the EU, so an EU SIM works on every island as at home, just as on the mainland.
Do UK phones roam in Tenerife?
Yes, on the operator's own terms. Since 2021 UK SIMs are not covered by EU roaming rules, so what Tenerife costs depends on your tariff: check it before you fly, or use a travel eSIM for data.
Is there signal on the ferries between islands?
Near the coast, phones use land networks. Further out the signal can fade, and if the ship runs its own mobile network, your phone may switch to it and your home operator bills it separately. Keep data roaming off on your home line while you sail.
Which emergency number in the Canaries?
112, for all emergencies, as everywhere in Spain. For the police, 091 reaches the National Police and 062 the Guardia Civil.
The short version
The Canary Islands are Spain and inside EU roaming, so EU SIMs work as at home, while UK SIMs depend on the operator. With a SIM from outside the Roam Like at Home area, one Spain plan covers every island; keep your home line's data roaming off on ferries, download maps for the mountain roads and save 112.

When should I activate my Spain eSIM?
Each plan shows before you pay when it starts counting. Plans that start on connection start counting the first time they connect to a network in one of the countries they cover: install the eSIM before you leave, keep the line off until you arrive in Spain, and you'll have data as soon as you land. Some also work in other countries (each plan lists which): if the line connects earlier, at home or on a layover, it starts counting there. Plans that start when you buy them are best bought on the day you'll start using them.
