Cheapest unlimited eSIM for Portugal? From €5.50 for 3 days (October 2026)
If you’re travelling to Portugal and want unlimited data without any nasty surprises on your bill, Roam2Go’s unlimited plan starts from €5.50 for 3 days — an option especially designed for short breaks to Lisbon, Porto or the Algarve. This eSIM is ideal above all for travellers coming from outside the EU (USA, UK, Latin America or Asia), where roaming in Europe tends to come at a high additional cost or simply isn’t included in the plan.
Who is this eSIM for Portugal for?
Within the European Union and the European Economic Area, local lines already benefit from «roaming like at home»: you can use your data in Portugal at no extra cost. But if you have a line from the USA, the UK, Canada, Latin America or Asia, the situation is different: roaming can be expensive, limited or simply non-existent on your plan.
In these cases, a local eSIM like Roam2Go’s is the cleanest solution: you buy the plan online before leaving home, activate it in minutes with a QR code, and arrive in Portugal with data up and running. A fixed price in euros, with no currency conversions or unexpected charges.
It’s also useful for European travellers who want unlimited data without eating into the fair-use limit of their home plan during the trip.

Unlimited plans for Portugal: 3, 5 and 7 days (and more)

- 5-day unlimited: €7.95

How do unlimited plans work?
Unlimited plans include a daily data allowance at high speed. Once exceeded, the speed is reduced until the allowance renews the following day — with no disconnection. For everyday use such as maps, social media, messaging and web browsing, this is generally more than enough. If you plan on heavy streaming or working remotely with large files, bear this in mind.
Fixed-data plans: an affordable alternative for short visits
If your data usage is moderate — occasional map searches, messaging, photos on Instagram — you may not need an unlimited plan. Roam2Go also offers fixed-data plans for Portugal, which can be the more affordable option for very short stays or light usage:
| Data | Validity | Price |
|---|---|---|
| 1 GB | 7 days | €1.88 |
| 3 GB | 7 days | €2.95 |
| 2 GB | 15 days | €2.95 |
| 5 GB | 15 days | €3.95 |
| 3 GB | 30 days | €4.95 |
| Unlimited | 3 days | €5.50 |
| 10 GB | 30 days | 5.95 € |
| Unlimited | 5 days | €7.95 |
| 15 GB | 30 days | €8.99 |
| 20 GB | 30 days | €9.50 |
| Unlimited | 7 days | €10.99 |
| Unlimited | 10 days | €13.95 |
| Unlimited | 15 days | €19.50 |
| 30 GB | 30 days | €23.95 |
| 50 GB | 30 days | €24.99 |
| Unlimited | 20 days | €25.99 |
| Unlimited | 30 days | €29.50 |

How to choose the right plan for your trip to Portugal
Weekend break (2–3 days)
If you’re heading to Lisbon or Porto for a few days, the 3-day unlimited plan at €5.50 is a very competitive option. You get unlimited data to get around the city without a worry, and the price is hard to beat. If you expect very light usage, the 1 GB plan may well be enough.
Full week (5–7 days)
For a week-long trip — combining Lisbon, the Algarve, Sintra or any other route — the 5-day (€7.95) or 7-day (€10.99) unlimited plans cover the period nicely. If you’d prefer a fixed-data plan and your usage isn’t intensive, the 5 GB or 10 GB plans can be an affordable alternative.
Extended stays or digital nomads
If you’re working remotely from Portugal or staying for a fortnight or more, the 15- or 30-day unlimited plans (or fixed-data plans with more GB) will give you peace of mind without having to top up every few days.
