Cheap eSIM for Portugal: the real cost per day (and the cap trap to avoid)
Key facts
- A cheap eSIM for Portugal starts at USD 15.90 for 5 days and falls to USD 1.78 per day on the 60-day plan.
- Every VoaSim plan is truly unlimited — no cap, no throttling — so heavy map and video use does not increase the price.
- Add a second eSIM in the same order for 10% extra off; trips of 1 to 4 days pay the 5-day package.
- The eSIM connects automatically to MEO, Vodafone and NOS, with solid coverage from Lisbon to Madeira, on land only during cruises.
- Days start counting at the first connection in Portugal, so you can install at home and keep the line off until you land.
See the exact price for your dates
"Cheap" only means something once you know what you actually pay per day of your trip. A 1 GB package can look cheaper than anything else until day three in Lisbon, when Google Maps, WhatsApp video and a few Reels have eaten it and you are buying a top-up at an airport-grade price.
This page shows the real per-day cost of a VoaSim eSIM for Portugal, how the rate falls as your trip gets longer, and how to check your exact price in about a minute.
VoaSim price table for Portugal (and the cost per day)
Price set by destination and trip length, across our 160+ destinations. All of them include unlimited data with no cap and no throttling. Prices below already include today's 15% promo.
| Plan | Price | Cost per day |
|---|---|---|
| 5 days | USD 15.90 | USD 3.18 |
| 7 days | USD 22.90 | USD 3.27 |
| 10 days | USD 29.90 | USD 2.99 |
| 15 days | USD 42.90 | USD 2.86 |
| 30 days | USD 60.90 | USD 2.03 |
| 60 days | USD 106.90 | USD 1.78 |
The pattern is simple: the longer the plan, the cheaper each day gets. A 30-day eSIM costs about half per day what a 5-day eSIM costs. Trips of 1 to 4 days pay the 5-day package, and the maximum is 90 days per eSIM. Run your exact dates in the price simulator.
Why by-GB plans stop being cheap in Portugal
Most budget eSIMs sell gigabytes. The headline number is low because the allowance is low. Then you land and your real usage starts: walking navigation across Alfama, a Google Maps drive down to the Algarve, live translation in a restaurant, video calls home, uploading photos from Madeira, a Netflix episode on the train to Porto.
Two things then happen with capped plans. Either you run out and buy a top-up at a worse rate, or you start rationing — screenshotting maps, skipping video calls, hunting café Wi-Fi. That is a hidden cost too.
With VoaSim there is no data cap, no speed throttling and no quiet "fair use" clause. The price you see is the price for the whole trip, whether you use 2 GB or 60 GB. If you are a genuinely light user on a two-day stop, a small by-GB package may still be the cheaper pick — that is a fair call. For anything longer, unlimited usually wins. See the full comparison.
Two travelers? Take 10% off the second eSIM
An eSIM is tied to one phone, so a couple needs two. Add a second eSIM in the same order and it gets 10% extra off. Sharing your connection (hotspot or tethering) is not allowed: the local carrier may block your line. Each traveler uses their own eSIM, and 2 or more eSIMs get an extra 10% off.
Practical family setup for Portugal:
- Both adults get their own eSIM, so both have maps and can be reached separately.
- Kids' phones can stay on Wi-Fi if they mostly use messaging at the hotel.
- Match the plan length to the trip, not to the shortest leg — a 10-day plan is cheaper per day than a 7-day one and gives you slack.
Going on to Spain or France afterwards? The same eSIM logic applies across our Europe plan covering 39 countries, so you do not buy a new one at the border.
Today's prices
Today's promo prices (15% off). Each destination has its own price. 2 to 4 eSIMs in the same order: 10% extra off. Trips of 1-4 days use the 5-day package.
Coverage in Portugal: what you actually connect to
The eSIM connects automatically to local networks — MEO, Vodafone and NOS — with no manual setup. Portugal has some of the best coverage in Europe: strong 4G reaches small interior villages and the islands, and 5G is available in parts of Lisbon and Porto where the network supports it (we do not promise 5G, it depends on your phone and location).
Where people use it most:
- Lisbon: maps in the tight streets of Alfama and Bairro Alto, tram info, ride apps.
- Porto: Douro valley day trips, train times, restaurant bookings.
- Algarve: beach routes and rental-car navigation between Lagos and Tavira.
- Madeira and the Azores: mountain roads where offline maps often fail.
One limit to note: on a cruise stopping in Lisbon or Funchal, the eSIM works on land, in port — not at sea.
Cheap versus carrier roaming and a local SIM
Fair comparison, no numbers we cannot verify:
| VoaSim eSIM | Carrier roaming | Local SIM in Portugal | |
|---|---|---|---|
| Price | Fixed per duration, from USD 1.79/day | Usually charged per day of use or bundled; check your carrier app | Varies by shop and package |
| Data | Unlimited, no throttling | Often a daily allowance, then reduced speed | Sold by GB in most cases |
| Setup | QR by email in minutes, install at home | Usually enable before you fly | Shop visit, passport registration, SIM swap |
| Your number | Stays active on your physical SIM | Stays active | Leaves the phone while you travel |
Roaming can genuinely be the better choice if your plan already bundles Europe at no extra cost — check the current rate in your carrier's app before buying anything. More detail on roaming.
Buying and installing without wasting a day of plan
Your days start counting at the eSIM's first connection to a network in Portugal, not at purchase. So you can buy early and install at home with zero risk — just keep the eSIM line switched off until you land (on Android, do not turn on the eSIM's data before the trip).
- Check compatibility: dial *#06#. If an EID appears, your phone supports eSIM. iPhone XR or newer, Galaxy S20 or newer, Pixel 3 or newer, and most phones from 2020 on. Carrier-locked phones must be unlocked.
- Pick your dates in the simulator and pay by international credit or debit card in USD via Stripe. Invoice by email, no hidden fees.
- The QR code arrives by email within minutes. Install it before you fly.
- In Lisbon or Porto, turn the eSIM line on and switch off your home carrier's data roaming.
