Portugal has a few main SIM card options, so I looked at MEO, Vodafone, and NOS in terms of price, data, coverage, validity, where to buy, and how easy they are to set up.
Quick picks: the best SIM card for Portugal is MEO because of its lower-cost “all traffic included” plans and wide availability across airports and city stores. All traffic included means you’re not limited by a fixed data cap, though speeds may be reduced with heavy usage.
SIM cards are usually cheaper than eSIMs, but they require more effort, from registration to choosing and activating a plan after purchase. Because of that, eSIM alternatives tend to be the simpler option, especially for short trips where minimizing setup time makes a difference.
Pro tip: It’s worth checking when the best time to visit Portugal is and mapping out your itinerary in advance, since both can affect travel costs and how busy different areas get.
Quick verdict: If you’re traveling and expect to use heavy data, MEO is the best choice thanks to its lower entry price for unlimited-style plans and easy availability across the country.
| Provider | Price (from) | Data | Validity | Network coverage in Portugal | Where to buy | Best for |
| MEO | €10 (~$11) | All traffic included | 15 days | Strong nationwide coverage | Airports, MEO stores, online | Heavy data users, simple setup |
| Vodafone | €20 (~$22) | 25GB + calls/SMS | 30 days | Strong in cities and most regions | Airports, kiosks, Vodafone stores | Balanced data + calls/texts |
| NOS | €19 (~$21) | 100GB + calls/SMS | 30 days | Strong speeds, wide 5G coverage | NOS stores, online | High data on pay-as-you-go |
Buying a SIM card at the airport is the most convenient option since all three providers are available right away. This is useful if you’re following a Portugal itinerary with multiple stops. For better value, consider city stores or online options.
MEO and Vodafone both offer “all traffic included” options with no fixed data cap, while NOS focuses on high data bundles with a set GB allowance. The difference comes down to pricing and availability, with MEO generally being easier to find and more accessible for travelers.
For short trips, MEO’s 15-day plan is the simplest to use, while longer stays may benefit from 30-day plans like Vodafone or NOS to avoid frequent top-ups. Coverage also matters. MEO is known for strong nationwide reliability, while Vodafone and NOS perform well in cities and most regions.
Finally, consider whether you need calls and texts. Vodafone and NOS include them in their plans, while MEO’s main tourist-friendly option is more data-focused depending on how you plan to stay connected.
The three best SIM card providers in Portugal are MEO, Vodafone, and NOS. These networks offer the best combination of coverage, pricing, and accessibility for travelers, with options ranging from unlimited data tourist SIMs to flexible prepaid plans.
Keep in mind that exact bundles and promos can change, so it’s best to confirm the latest offers in-store or on the provider’s official website before buying.
MEO is one of the largest telecom providers in Portugal, known for strong nationwide coverage and reliable speeds. It’s widely available across the country, including airports and city centers. Best for travelers who want a simple, ready-to-use SIM with minimal setup.

Quick verdict:
MEO is a strong overall choice for travelers thanks to its reliable nationwide coverage and flexible prepaid options, from simple “all traffic included” plans to more customizable pay-as-you-go setups. Easy to buy online or in stores across Portugal, it’s a convenient option, though some plans may require extra setup compared to tourist-focused SIMs.
Vodafone is one of the main telecom providers in Portugal, known for reliable coverage and strong performance across cities and most regions. It offers tourist-friendly prepaid SIMs that are ready to use and easy to understand. Best for travelers who want a straightforward plan with clear inclusions.
| Duration | Data | Price | Notes |
| 30 days | 25GB + 500 mins/SMS + 50 international mins/SMS | €20 (~$22) | Vodafone Travellers, all-in-one tourist SIM |
| 30 days | All traffic included (Portugal only) | ~€35 (~$38) | Vodafone Go Total, no data cap, speeds may be managed |
Quick verdict:
Vodafone is a strong choice for travelers who want simple, ready-to-use prepaid plans with clear inclusions. Its options cover both balanced use with data, calls, and texts, and heavier data needs with “all traffic included,” meaning no fixed data cap, though speeds may be reduced with heavy usage. Easy to find at airports, kiosks, and Vodafone stores across Portugal.
NOS is one of the main telecom providers in Portugal, offering strong speeds and widespread 5G coverage. Its prepaid plans are known for high data allowances at competitive prices. Best for travelers who want a pay-as-you-go SIM with a large data bundle and included calls and texts.
| Duration | Data | Price | Notes |
| 30 days | 100GB + 1200 mins/SMS + bonus data (promo) | €19 (~$21) | Includes international minutes |
Quick verdict:
Best for travelers who want a pay-as-you-go SIM with a large data allowance and included calls and texts at a competitive price. NOS also offers higher data plans with lower monthly rates, but these typically require a 6-month contract, making them less suitable for short-term visitors, though they can be useful if you’re staying longer, such as on a Portugal digital nomad visa.
In my trips, relying on SIM cards always took more time than expected. Between registration, choosing the right plan, and activating it through an app or SMS, it’s not always as quick as just inserting the SIM and going online.
At some point, I tested eSIMs like Holafly, Ubigi, and Jetpac during my travels instead of relying on physical SIM cards. The biggest difference was how much time it saved. There’s no need to visit a store, deal with registration, or figure out which prepaid plan to load after arrival.
From looking through travel threads and discussions, this seems to be a common recommendation as well. When people ask about SIM cards for Portugal, they’re often pointed toward eSIMs instead, with many travelers sharing that they’ve had smoother and more convenient experiences using them.
For shorter stays, eSIMs tend to be the more practical option. Everything is set up before the trip, so you’re connected immediately once you land, without going through the usual setup steps that come with local SIM cards.
| Provider | Price (from) | Data | Validity | Best for | |
| Holafly |  | $27.30 | Unlimited data | 7 days | Simple setup, heavy data use |
| Ubigi |  | $24 | Unlimited data | 7 days | Flexible plans, light users |
| Jetpac |  | $33.99 | Unlimited data | 10 days | Budget-friendly, short trips |
