Will I have signal in the Serra da Estrela mountains?

In the villages and around Torre you'll usually get a workable signal, but it drops on the higher trails, remote passes and in poor weather. Download maps and check conditions before heading up.

Can I reach Fátima and Tomar easily with the same plan?

Yes. The single Portugal plan covers the whole Centro region, including Fátima, Tomar, Leiria and Viseu. Coverage in these towns is reliable, so live maps and bus or train times work fine.

Good to know in Centro

Centro mixes well-connected cities with the wild Serra da Estrela, where roads climb above 1,900 metres. If you're heading to Torre in winter, check live weather and road conditions on data before you drive, as passes can close with snow.

Best time to visit Centro

Late spring and early autumn bring warm, comfortable days for the cities and coast; winter adds snow to the Serra da Estrela for Portugal's only ski slopes.

Two simple ways to buy

Centro eSIM plans: unlimited, or by the GB.

Every Centro eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Centro — you can always top up or switch on your next trip.

Traveller streaming and browsing freely on an unlimited-data travel eSIM

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

Centro eSIM: your local data guide.

Central Portugal spans Coimbra's UNESCO university, Aveiro's moliceiro canals, the pilgrim shrine at Fátima, the Templar castle at Tomar and the snow-capped Serra da Estrela. A Centro eSIM keeps your train times, museum bookings and mountain-weather checks live as you move between historic cities and Portugal's highest peaks.

One eSIM for Centro and all of Portugal. It's the national Portugal eSIM — from $2.15/day with unlimited data, working the same in Centro as it does the moment you leave it.

Landing at Porto - Francisco Sá Carneiro (OPO)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

Across the region

Where you'll lean on data in Centro.

Coimbra

In Coimbra, coverage is strong for navigating the hilltop university and the old town's stepped lanes.

Aveiro

Around Aveiro's canals and Costa Nova's striped houses, you'll get reliable 4G and 5G for boat tours and photos.

Serra da Estrela

Up in the Serra da Estrela around Torre, Portugal's highest point, mountain signal drops, so download trails and roads first.

Fátima & Tomar

In Fátima and around Tomar's Convento de Cristo, data holds up well for the sanctuary and castle visits.

The practical bit

Getting around Centro on your eSIM.

Apps you'll want online in Centro

CP— Comboios de Portugal app; fast trains link Coimbra, Aveiro and the region to Lisbon and Porto.
Bolt— Ride-hailing in Coimbra, Aveiro and other Centro cities.
Uber— Available in the larger Centro cities for city rides and station runs.
Moovit— Plan local buses in Coimbra, Aveiro and out towards the smaller towns.

How long to stay in Centro

Four to six days lets you pair Coimbra and Aveiro with Fátima, Tomar and a couple of days in the Serra da Estrela without rushing.

How much data for Centro

Balanced sightseeing across cities and mountains runs comfortably on 3-5 GB for several days; go Unlimited if you'll stream on trains or hotspot in the Serra da Estrela.

Coverage in Centro

Coimbra, Aveiro, Viseu and the main towns enjoy strong 4G and 5G, but coverage realistically thins on the high Serra da Estrela passes, forest trails and remote interior roads.

Centro eSIM questions, answered.

Yes. Both cities have strong MEO, NOS and Vodafone 4G and 5G, so maps, trains and bookings work smoothly. You'll only notice signal weakening once you head up into the surrounding hills and the Serra da Estrela.
