Is there good signal up at the historic university?

Yes. The hilltop Alta and the University of Coimbra are well covered, so you can use maps between the Joanina Library, the bell tower and the Se Velha, though thick stone interiors may weaken data indoors.

Can I use the same eSIM travelling on to Porto or Lisbon?

Absolutely. It's a national Portugal plan, so one eSIM covers Coimbra and onward trips north to Porto or south to Lisbon. The main railway line stays connected, ideal for maps and messages between cities.

Good to know in Coimbra

Coimbra has no airport, but it sits on the main Lisbon-Porto rail line, so trains from either airport city stay well connected. Coimbra-B is the fast-train stop, a short shuttle from the centre, so map the transfer before you arrive.

Two simple ways to buy

Coimbra eSIM plans: unlimited, or by the GB.

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

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.

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.

How much data do you need in Coimbra?

A rough, honest guide to sizing your Coimbra eSIM so you're not guessing. Most travellers in Coimbra are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Coimbra eSIM: your local data guide.

Coimbra climbs steeply from the Mondego river to one of Europe's oldest universities, where the Baroque Joanina Library and the bell tower crown the hilltop Alta. A Coimbra eSIM keeps timed library tickets, fado-house bookings and the maze of steep alley maps on hand as you wander between the Se Velha cathedral and the student-filled Baixa below.

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

Landing at Porto Airport (OPO), about an hour north (Lisbon LIS is a similar distance south)?

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

On the ground

Where you'll lean on data in Coimbra.

University of Coimbra (Alta)

Reserve timed slots for the Joanina Library and bell tower, then translate the Latin inscriptions as you cross the Paco das Escolas.

Baixa & Rua Ferreira Borges

Navigate the lively lower town's shops and cafes, book a Coimbra fado show and split a Bolt up the steep hill afterwards.

Se Velha (Old Cathedral)

Map the twisting medieval lanes to the fortress-like Old Cathedral and pull up its opening hours before the climb.

Mondego Riverside & Quinta das Lagrimas

Cross the Santa Clara bridge for river views, check Portugal dos Pequenitos times and book a spot in the Quinta das Lagrimas gardens.

The practical bit

Getting around Coimbra on your eSIM.

Apps you'll want online in Coimbra

SMTUC— Coimbra's municipal buses and historic trolleybuses; routes up to the university, with live times over data.
Bolt— Ride-hailing around the hilly student city; book and pay without cash over data.
CP - Comboios de Portugal— App for trains stopping at Coimbra-B on the main line; check times over data.
Uber— Also available in Coimbra; handy for the steep climb back from the riverside, needs data.

How long to stay in Coimbra

Coimbra is often a one- or two-day stop between Lisbon and Porto, enough for the UNESCO-listed university, the Joanina Library and a stroll along the Mondego river.

How much data for Coimbra

A short stay here needs little, around 1-2 GB for maps, onward train tickets and university photos; only reach for a balanced 3-5 GB if Coimbra anchors a longer central-Portugal road trip.

Coverage in Coimbra

The city centre, university hill and Coimbra-B station hold steady 4G/5G on the main networks; signal can weaken in the steep medieval alleys of the old town and out in the rural Mondego valley beyond.

Peace of mind

Your Coimbra eSIM: data-only, zero bill shock.

Your Coimbra eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Coimbra, no swapping your real SIM out.

The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.

No roaming bills, ever

Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.

One thing worth knowing

Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
