Staying online in the Canary Islands is easy, cheap and mostly just works — but there are a few things worth knowing before you travel. The islands are part of Spain and the EU, so European visitors keep their normal mobile allowances, while UK travellers need to check their roaming charges after Brexit. Local SIMs and eSIMs are inexpensive if you would rather not roam, hotel and café Wi-Fi is widespread, and 4G and 5G coverage is good across the resorts and towns — though it can drop out dramatically once you head into the mountains. This guide explains roaming, SIMs, Wi-Fi and coverage so you arrive knowing exactly how to stay connected.
First, where exactly are you?
It is worth remembering that although the Canaries sit off the coast of Africa, they are fully part of Spain and the European Union — which is what makes EU roaming rules apply here just as they would on the mainland. If you are curious about that geographical quirk, our explainer on whether the Canary Islands are in Spain or Africa is a good read. For connectivity purposes, treat them as EU Spain.
Roaming: EU visitors vs UK visitors
Travellers from the EU
If your mobile plan is from an EU country, "roam like at home" rules mean you use your normal minutes, texts and data allowance in the Canaries at no extra cost, exactly as you would back home. There is usually nothing to set up — your phone simply connects to a Spanish network on arrival. Very large data plans can occasionally hit a fair-use roaming cap, so if you use a lot of data check your provider's fair-use limit before you travel.
Travellers from the UK
Since Brexit, the UK is outside the EU roaming zone, and many British networks have reintroduced roaming charges or daily roaming fees for use in Spain and the wider EU. Some plans still include EU roaming, some charge a modest daily fee, and some are expensive — it varies enormously by provider and tariff.
Check your UK network's current roaming terms before you fly — daily fees and data caps change from time to time. If roaming is costly on your plan, a local SIM or eSIM (below) is usually far cheaper. Whatever you do, avoid drifting onto a non-EU network signal from Morocco if you visit the easternmost islands, as that can trigger much higher charges.
Spanish SIMs and eSIMs
If roaming does not suit you, a local prepaid SIM or an eSIM is a cheap, simple alternative and gives you a generous data allowance for the length of a typical holiday.
- Physical prepaid SIMs from the main Spanish networks are sold in phone shops, some supermarkets and at the airport. Bring photo ID (registration is required in Spain), pop the SIM in an unlocked phone and you are away. Tourist-oriented data bundles are excellent value.
- eSIMs are the easiest option if your phone supports them — you buy a Spain or Europe data plan online before you travel, scan a QR code and activate it on arrival, with no shop visit and no swapping out your home SIM. Ideal for short trips and for keeping your usual number reachable on Wi-Fi.
For most holidaymakers an eSIM data plan bought before departure is the least hassle; for longer stays a local physical SIM with a big monthly bundle often works out cheapest. Either way, the low cost of data here means you can navigate, translate and share photos freely. If you are staying long-term or working remotely, our digital nomads guide goes deeper into connectivity for extended stays.
Wi-Fi in hotels, cafés and public spaces
Free Wi-Fi is the norm in Canarian hotels, apartments, bars, cafés and restaurants, and in many public squares and shopping centres. Quality ranges from excellent to patchy — big modern hotels and coworking-friendly cafés are generally fast and reliable, while older apartment blocks and busy beach bars can be sluggish, especially in the evenings when everyone is online at once. If reliable internet matters for your trip (video calls, remote work), check recent guest reviews that specifically mention Wi-Fi speed before you book.
On any public or hotel Wi-Fi, use a little caution: avoid logging into banking or entering payment details on open networks, and consider a VPN if you handle sensitive work. For everyday browsing, messaging and streaming it is perfectly fine.
Coverage: great in town, patchy in the mountains
Across the resorts, towns and main roads, mobile coverage is strong, with widespread 4G and growing 5G. Where it falls away is in the islands' dramatic interior — deep barrancos (ravines), high volcanic terrain, the laurel forests and the remote western isles can all leave you with weak signal or none at all. This matters most if you are hiking or driving inland.
- Download offline maps and any route notes before you head into the mountains or along the wild coastline.
- Don't rely on signal for navigation or emergencies on remote trails — carry a paper backup for serious walks.
- The high peaks — around Teide, Roque de los Muchachos and the deep calderas — are especially prone to dead zones.

Keeping costs down
Data itself is inexpensive here, so the main way people get stung is roaming on an unsuitable UK plan. A quick check of your tariff before you fly — and an eSIM if the numbers look bad — is all it takes to avoid a nasty bill. Our costs and money guide covers budgeting for the rest of your trip, from IGIC (the islands' low local sales tax) to typical prices.
The bottom line
Connectivity in the Canaries is genuinely easy: EU visitors roam for free, UK visitors just need to check their plan and grab an eSIM if it is pricey, and free Wi-Fi is everywhere. Sort your mobile setup before you travel, download offline maps for the mountains, and you will stay comfortably connected throughout your holiday — with the freedom to switch off and enjoy the beach whenever you choose.
