Internet, power and coworking on the south Tenerife coast
What the fibre actually delivers, how much upload a call needs, what an isolated island grid means, and the handful of desks you can rent.
The connectivity question in south Tenerife is not whether the island has fibre. It is whether the particular flat has it, what the upload looks like, and what you do on the day something fails. The archipelago-wide numbers are good: in national coverage figures published in May 2026, 5G reached 99.1 per cent of Canarian households, fibre more than 91 per cent and gigabit-capable networks 90.6 per cent.
#Which operators serve the south and what they sell
Four operators run their own networks in Spain — Movistar, Vodafone, Orange and Digi — and a long list of brands resells over them, including Yoigo, Lowi, O2, Pepephone and Finetwork. All four sell the same shape of product in the Canaries: fibre to the flat at 300, 600 or 1,000 Mbps, usually bundled with a mobile line.
The useful part is that Spanish fibre is close to symmetrical. On a gigabit tier the measured upload sits within a few megabits of the download, which is not true of the cable and copper products still common in parts of northern Europe. That single fact is why calls from here tend to be better than people expect. Contracts usually carry a minimum term, though several operators market tariffs without one.
#How much upload speed does a video call actually need
Far less than the number on the tariff. Zoom's own published figures ask for 600 kbps up and down for a good one-to-one call, 1.2 Mbps for 720p and 3.8 Mbps up for 1080p; a group call wants 2.6 Mbps up at 720p and 3.8 Mbps up at 1080p.
So a call needs single-digit megabits of upload, not hundreds of anything. What breaks calls is rarely capacity. It is jitter and packet loss, an access point two rooms and a concrete wall away, or a cloud backup running unnoticed. Test the upload figure and how steady it is, and ignore the headline.
#Is a phone a usable backup
Yes, and it is the most effective insurance you can carry. Coverage across the built-up south is strong, and tethering a laptop to a phone will carry a video call comfortably.
The Canary Islands are an outermost region of the European Union, so an EU SIM roams there under the roam-like-at-home rules at domestic prices, subject to the usual fair-use policy. A British SIM is a separate question after Brexit and depends entirely on whether that operator still includes the islands in its European zone, so check rather than assume. For a stay of a month or more, a Spanish prepaid SIM or eSIM on a second network is cheap and gives you a genuinely independent path when the fixed line goes down.
#How reliable is the electricity
Better than the mainland in one specific way and worse in another. The Canaries are not connected to the peninsular grid, and the archipelago runs six separate island systems, which is why the islands were untouched by the Iberian blackout of 28 April 2025 while mainland Spain and Portugal went dark.
The other side of an island system is that it has failed on its own. Tenerife lost power across the whole island on 29 September 2019, for about nine hours and affecting more than nine hundred thousand people, after a failure at the Granadilla substation, and again in July 2020. These are rare events rather than a weekly hazard, and the hedge is the ordinary one: a laptop with real battery life, a charged phone, and work saved somewhere that is not only on your desk.
One footnote from 2025 is worth carrying. Even though the Canaries kept their electricity that day, networks in the islands were disrupted, because operators keep core systems on the mainland. Power and connectivity are not the same failure.
#Where can you work outside the flat
There are only a handful of coworking spaces on the south coast, and the list changes, so confirm before you count on one. Three that were operating at the time of writing give a fair sense of the range.
Seaside Coworking in Los Cristianos, on Paseo Berlín, has shared and fixed desks, three small private offices, soundproofed call booths, a meeting room, gigabit wifi and round-the-clock access by PIN. A coworking space in Fañabé, Costa Adeje, on Calle Montaña Clara, offers desks, a meeting room, parking and daytime opening, sold by the day, the week or the month. Work 'n Mates in El Médano, on Plaza de Galicia, is a small space for around eight people with a call booth and an outdoor working area, open on weekdays and aimed at people staying two or three months and longer.
Monthly desks in the south have been advertised from around 150 euros, with day and week passes at the larger spaces. Rates and hours move, so ask for a day pass before committing to a month.
#Cafés or a desk at home
Cafés on this coast are for an hour of email, not a working day. They are set up around coffee and lunch service, the tables are small, the wifi is variable, and a call taken at one is unfair on everybody within earshot.
For anything with a camera on it you need a door, or a booth. That is the real argument for a coworking membership, and also for a second room rather than a studio: not the floor area, but the ability to close something.
#What to test in the first hour
Everything you would otherwise complain about later. It takes twenty minutes on the first afternoon and is almost impossible to do usefully in the last week.
If the upload is poor, say so in the first two days. A landlord can often move a router, add a mesh point or move up a tier quickly, and nobody can fix it retrospectively.
