A trip to Madeira often means walking the levadas; in the Azores it might mean crater lakes, a whale-watching trip and a flight to another of the nine islands. Both archipelagos are Portugal and inside EU roaming, so roaming is simple for EU SIMs. Coverage is the harder part: in ravines, in tunnels and out at sea, the signal can fade.
This guide covers eSIM and mobile coverage in Madeira and the Azores: roaming for EU and other SIMs, where the signal fades on trails and boat trips, travelling between islands, the plan that covers both archipelagos, and staying safe on remote walks.

- Local networks: NOS, MEO, Vodafone (depending on the plan)
- Coverage: the signal can fade on trails, in ravines and tunnels, and out at sea
- Emergency numbers: 112
- Embassies: in Lisbon, with consulates in Porto for some countries
EU roaming in Madeira and the Azores
Madeira and the Azores are Portuguese autonomous regions and part of the EU, so Roam Like at Home applies there as on the mainland: an EU SIM works as it does at home.
Visitors with a British, American or Brazilian SIM usually pay roaming by the day, depending on the operator, so check your tariff before you fly.
Mobile coverage in Madeira and the Azores: where it fades
Madeira's levada walks follow irrigation channels through valleys and tunnels, and the signal can fade in both. In the Azores, trails around the crater rims and down into ravines can lose it too. Treat your phone as a help on these walks, not your only guide.
Before a remote walk, download offline maps, carry a torch for the levada tunnels, check the weather and tell someone your route and when you expect to be back.
Island hopping and boat trips
The nine islands of the Azores are linked by flights and, mainly in summer, by ferries. With a Portugal plan, nothing changes when you fly or sail between islands, because Madeira, the Azores and the mainland are all part of Portugal.
Out at sea, on a ferry or a whale-watching boat, the signal can fade, so download what you need before you board. If a ship runs its own onboard mobile network, your home operator bills it separately, so keep your home line's data roaming off while you sail, and turn it back on ashore if you use it for data.
Which plan fits your trip
With an EU SIM, you need nothing extra on either archipelago, unless your tariff includes little data abroad.
With a SIM from outside the Roam Like at Home area, a Portugal plan covers Madeira and the Azores as well as the mainland, so one eSIM works on every island. For a trip that also takes in another country, the Europe plans cover Portugal, Madeira and the Azores included, among 38 destinations.
Telcomia's standard plans are data only, with calls through apps such as WhatsApp. Each plan's details show the Activation line, the duration, the data and whether you can share the connection, and you can create an account to track your data use.
Before you leave
- 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 the trails and islands you plan to visit.
- Pack a torch for the levada tunnels and a power bank for long walks.
- Save 112 in your contacts.
Consular protection: who to call on the islands
- 112 reaches the police, an ambulance and the fire service, on the islands as on the mainland.
- Embassies are in Lisbon, and some countries also have consulates in Porto. The Telcomia app shows which mission is responsible for you, with address and phone.
- Emergency phrases in Portuguese are ready to show on screen in the app.
Questions travellers ask about Madeira and the Azores
Does EU roaming work in Madeira and the Azores?
Yes. Both are part of Portugal and of the EU, so an EU SIM works there as at home under Roam Like at Home. A SIM from outside that area follows its operator's roaming terms.
Is there signal on Madeira's levada walks?
Not everywhere: the levadas run through valleys and tunnels where the signal can fade. Download offline maps, carry a torch and tell someone your route before you set out.
Does a Portugal eSIM work in the Azores?
A Telcomia Portugal plan does: it covers Madeira and the Azores as well as the mainland, because both are part of Portugal. You can move between islands without changing anything.
Which emergency number should I call?
112, for the police, an ambulance or the fire service, on the islands as on the mainland. On a remote trail or out at sea, remember that a mobile call needs a signal.
The short version
Madeira and the Azores are Portugal and inside EU roaming, so EU SIMs work as at home, and with a SIM from outside the Roam Like at Home area one Portugal plan covers both archipelagos. The signal can fade in levada tunnels, ravines and out at sea, so download maps first, tell someone your route and keep 112 in mind.

When should I activate my Portugal 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 Portugal, 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.
