The best eSIMs for Portugal – detailed list
After testing eSIM providers firsthand during my travels across Portugal (from Lisbon to the Algarve), I narrowed it down to the 5 best options. These picks offer the best mix of coverage, value, and ease of use for anyone visiting the country.
1. Saily – top eSIM pick for Portugal
| Rating: | |
| Supports 5G networks: | ✅ Yes |
| Countries and regions: | 200+ countries and regions |
| Starting price: | From $3.59 |
On my trip to Portugal, Saily quickly became my favorite eSIM. It has everything a traveler might need – affordability, reliable coverage, and ease of use. On top of that, it makes your connectivity safe with robust security features, such as virtual location, ad blocker, and web protection. But that’s not surprising considering that it’s been created by a security company, NordVPN.
Plan options. For a trip to Portugal, Saily offers a variety of data plans – local, regional for Europe, and global plans. Its main plans focus on mobile data, but users can now add a US phone number for calls, SMS, and 2FA verification for $0.99/month. However, this doesn’t include a local Portuguese number. On the bright side, I found Saily more affordable than many competitors.
Pricing. Saily’s cheapest 7-day plan costs $3.59 for 1GB, while its most expensive 30-day plan is $64.79 for unlimited data. The service is prepaid and even has a refund option if you cannot activate your plan.
| Data allowance | Duration | Price |

| Unlimited | 25 days | $59.39 |
| Unlimited | 30 days | $64.79 |
Network coverage. Saily eSIM delivers solid 4G/LTE and partial 5G coverage across Portugal. During my hands-on tests through Lisbon, Porto, and even train rides to Cascais, the connection stayed reliable and fast. While Saily doesn’t name exact partners, real-world performance didn’t disappoint.
My experience with Saily. Using Saily on my trip to Portugal was surprisingly smooth from the start. Activation happened automatically the moment I landed in Lisbon – no need to scan QR codes or dig through settings.
The app itself felt modern and easy to navigate, with all the essentials front and center. I could check my remaining data and top up in just a couple of taps. Throughout the trip, the connection stayed stable and quick, even while streaming music and navigating Google Maps.
I also reached out to customer support via live chat and was connected to a real agent in under a minute. They answered all my questions clearly and efficiently.
Overall, Saily felt like a thoughtfully designed, no-hassle solution for travelers who want reliable data without overcomplicating things. If you’d like to learn more about this provider, you can take a look at our in-depth Saily review.

| Rating: | |

| Countries and regions: | 200+ |

If Portugal is just one of several stops on your trip, Airalo is a solid choice. It offers affordable local, global, and regional plans for Europe. What I like about Airalo is that it makes staying connected easy and cost-effective as you move between countries.
Plan options. Airalo eSIM offers both regional and country-specific plans, which are great for travelers visiting multiple countries. All of its plans are data-only.
Pricing. Even though Airalo offers a free 1-day plan with 1GB, its other plans are among the most expensive on my list. For example, its starting 7-day plan costs $6.00 for 5GB, and the biggest 30-day plan is $49.99 for 80GB.
| Data allowance | Duration | Price |
| 1GB | 1 day | FREE |
| 5GB | 7 days | $6.00 |
| 10GB | 15 days | $11.00 |
| 20GB | 30 days | $19.00 |
| 30GB | 30 days | $27.00 |

| 80GB | 30 days | $49.00 |
Network coverage. Airalo connects to Portugal’s top mobile networks: NOS, Vodafone, and MEO – all of which support 5G. This ensures fast and stable connections throughout the country. During my testing in Lisbon and Porto, signal strength remained consistent, with smooth performance when using maps, social media, and streaming apps. Even on train routes between cities and in more rural areas, the connection held up well, making Airalo a reliable option for staying online across Portugal.
My experience with Airalo. Setting up my Airalo eSIM for Portugal was pretty simple. I installed it right after purchase, and it automatically activated once I landed without any manual steps or settings.
The app itself is clean and intuitive, with all key features – data tracking, top-ups, and plan details – clearly organized in the My eSIMs tab. While traveling through Lisbon and Porto, I had no trouble checking my data balance or adding more when needed.
The connection was consistently fast and reliable, even when streaming music or using Google Maps. I also reached out to customer support via live chat – the wait was under a minute, and the agent quickly resolved my question.
Overall, Airalo made staying connected in Portugal incredibly easy. For more insights, you can also read our Airalo review.
3. Jetpac – affordable Portugal eSIM with travel perks
| Rating: | |
| Supports 5G networks: | ✅ Yes |
| Countries and regions: | 200+ |
| Starting price: | From $1.00 |
I know that, at least for me, pricing often plays a significant role in my decision-making, and I like that Jetpac gets it. With its cheapest plan starting at only $1.00/GB, it ensures connectivity for travelers with different budgets. And that’s not all – it also offers travel perks like lounge access in the airport, so you can comfortably wait for your flight.
Plan options. Jetpac eSIM provides budget-friendly options for travelers and promotes its travel perks including lounge access in case of flight delays. Good for short-term travelers looking for an economic option.
Pricing. I was pleasantly surprised to learn that Jetpac has 10 plans for Portugal. One of its cheapest ones starts at $1.00/GB for 4 days, while an unlimited data plan costs $31.99 for 10 days. Without a doubt, it's the most affordable provider on this list.
| Data allowance | Duration | Price |
| 1GB | 4 day | $1.00 |
| 3GB | 7 days | $8.50 |
| 5GB | 30 days | $10.00 |

| Unlimited | 7 days | $24.99 |
| Unlimited | 10 days | $31.99 |
Network coverage. Jetpac connects to Optimus (NOS) and Vodafone, two of the main mobile networks in Portugal. Optimus supports both 4G and 5G, while Vodafone provides reliable 4G coverage. During my testing, connections remained stable with fast speeds, even in busy public areas. While 5G is available in some urban zones, coverage may vary in rural regions.
My experience with Jetpac. Using Jetpac on my trip through Portugal was a smooth ride for the most part. The activation was fully automatic. Once I landed and turned on data roaming, the eSIM connected to a local network without needing any manual setup.
The app itself is cleanly laid out, with Home, Packs, Help, and Profile sections that make everything easy to find. I could track my remaining data at a glance and top up with just a couple of taps. The guides were clear, and the interface didn’t overwhelm me with unnecessary options.
However, my first attempt at reaching live chat support was frustrating – a nearly 3-hour wait with no response. Thankfully, my second try the next day got me through to an agent in under a minute, and they were quick and helpful.
Overall, Jetpac’s app is easy to use day to day, and performance stayed stable across Lisbon and Porto, even while streaming and navigating maps. I also recommend reading our in-depth Jetpac review for more insights.
4. aloSIM – Portugal eSIM with SMS and calls
| Rating: | |
| Supports 5G networks: | ✅ Yes |
| Countries and regions: | 200+ |
| Starting price: | From $4.50 |
While most providers focus on data-only plans, aloSIM surpasses them with a local phone number, SMS, and calls. I strongly believe that it’s one of aloSIM’s major strengths. Other features, like broad coverage and ease of use, are commonly shared among other top eSIM providers.
Plan options. aloSIM eSIM has various regional and local plans. However, global plans aren’t available for this provider. All its plans are prepaid.
Pricing. For a short trip, I found its 7-day plan for $4.50/GB or a 15-day plan with 2GB for $7.00 the best. For a more extended trip, I recommend a 30-day unlimited data plan for $32.00.
| Data allowance | Duration | Price |
| 1GB | 7 days | $4.50 |
| 2GB | 15 days | $7.00 |
| 3GB | 30 days | $9.50 |
| 5GB | 30 days | $10.00 |
| 10GB | 30 days | $17.00 |

| Unlimited | 30 days | $35.00 |
Network coverage. aloSIM connects to NOS and Vodafone. Both offer strong 4G LTE and partial 5G coverage across the country. On my trip, the connection was consistently fast and reliable. Signal remained stable on train rides from Lisbon to Cascais, with no noticeable drops in speed when using maps or streaming content.
My experience with aloSIM. Setting up aloSIM took a bit more effort compared to other eSIMs I’ve tried. It requires manual activation through your phone’s settings. I followed its step-by-step guide (which was easy to understand), but I’d recommend installing the eSIM right before you actually need it, since your data plan starts ticking as soon as it’s activated.
Once I was connected, the experience was smooth. The app is clean and beginner-friendly, with all your active plans and remaining data clearly displayed in the My eSIMs section. Topping up only took a couple taps.
I did run into a support hiccup – the live chat never connected me to an agent, even after waiting nearly a full day. Submitting a support ticket through the app worked much better, though, I got a helpful reply within 20 minutes.
Overall, daily use was hassle-free, and the app made managing data abroad simple. If you’d like to learn more about this provider, you can check our Jetpac review.
5. Nomad – Portugal eSIM with ultra-fast speeds
| Rating: | |

One of Nomad’s major strengths is its reliable performance. Wherever I traveled in Portugal, I could find high-speed 5G or at least 4G connections. So, it’s my top pick for travelers prioritizing speed with their internet.
Plan options. Known for its high-speed connections, Nomad eSIM offers both regional and country-specific plans. Great if you need a reliable, fast connection.
Pricing. Plans begin at $4.50 for 1GB over 7 days, $9.00 for 3GB for 30 days, and $45.00 for a 30-day plan with 50GB. Though more expensive than the others, Nomad boasts high-speed connectivity.

Network coverage. Nomad connects to NOS and MEO, and the coverage didn’t disappoint. I used it across Lisbon, Porto, and even on the train to Cascais, and the signal stayed strong the whole way. Streaming, checking maps, and uploading photos worked without a hitch, even in more residential areas.
My experience with Nomad. Activating Nomad’s eSIM was super straightforward. It only kicks in once you arrive and connect to a local network with data roaming enabled, so no fumbling with early setup.
The app itself is easy to use, with simple tabs like Home, Manage, and Profile. I liked how easy it was to check my remaining data and see details like network speed and plan info. Topping up was a breeze too.
When I had a quick question, the live chat was responsive – I was connected to a helpful agent in under a minute, and they answered all my concerns thoroughly.
Overall, Nomad made managing my eSIM feel hassle-free, even if you’re new to this tech. Switching between plans depends on your phone, but on iOS and Android, it’s just a matter of toggling off one SIM and turning on another in settings. For more insights, you can check our Nomad review.

Here are the main factors I focused on:

Things to consider before choosing an eSIM for travel in Portugal
When choosing an eSIM for your trip to Portugal, it’s important to keep a few key factors in mind. Coverage, data allowance, and compatibility can make or break your mobile experience while traveling:
- Coverage. Ensure the eSIM provider covers the areas you will visit in Portugal. All my listed providers offer solid connections to the country's top networks.
- Data plans. Consider how much data you'll use during your trip. If you're only looking for internet access or also want to make calls and send texts, choose a plan that covers those essentials. Some providers offer flexible data options, while others include call and SMS support.
- Price. Look at the prices offered by different eSIM providers to find the best deal for your trip. Make sure there are no hidden fees so extra charges won’t catch you by surprise.
- Compatibility. Check if your phone or device supports eSIMs. Recent smartphones from Apple, Samsung, or Google usually support eSIMs.
- Activation process. Go for a provider that makes it easy to activate your eSIM. You should be able to buy and set up the eSIM online before you travel.
- Validity period. Think about how long you will be in Portugal and choose an eSIM plan that lasts as long as you need it. Providers offer many options, from short-term plans for a few days to longer ones that last a month.
Benefits of using an eSIM in Portugal
When I was traveling to Portugal, I didn’t even consider other options than an eSIM because it’s just convenient. What I like the most is that you don’t need to switch SIM cards or carry hardware. Instead, you can simply download the app. Of course, there are other benefits to using an eSIM, such as:
- No need for physical SIM cards. Since it’s software-based, you don’t need to replace a physical card or take any hardware device (just like you do with a pocket Wi-Fi). You can simply download an app and activate your eSIM before your trip.
- Save money on roaming. Many eSIM providers offer attractive pricing without the high costs of international roaming. This means you can enjoy affordable data plans that fit your usage needs without paying excessive charges.
- Instant connectivity. Most eSIMs activate automatically upon arrival in the destination country, so you don’t have to worry about having an internet connection to activate one.
- Security features. Some eSIMs even have built-in security features that protect from all kinds of threats lurking online. For instance, Saily offers virtual locations, an ad blocker, and web protection.
- Convenience for frequent travelers. eSIMs also provide unparalleled flexibility when traveling. You can easily switch between carriers and plans without replacing a physical SIM card.
How to activate eSIM in Portugal
Activating your eSIM is a simple process, and I’ve broken it down for you. Most providers support one of the three main activation methods, making setup quick and hassle-free. Whether you're using a QR code, manual input, or an app-based approach, you’ll be ready to go in minutes.
This is one of the easiest and most popular ways to activate an eSIM. Here's how the process typically goes:
- Choose a plan that fits your needs — Saily eSIM is a solid pick, now 5% OFF plus up to 5% cashback
- Download and install the provider’s official app
- Launch the app and tap the activation button to begin setup
The eSIM will install automatically on your device. In some cases, a few final settings may need to be adjusted to complete the activation.
QR-based installation works much like the app method, but activation is done by scanning a QR code instead of tapping a button. Here's how the process usually goes:
- Purchase the data plan that suits your needs
- Download your eSIM provider’s app
- Once the purchase is complete, you’ll get a QR code via email, along with step-by-step setup instructions
- Scan the QR code with your phone to start the installation
- Set the eSIM as your primary data SIM and turn on roaming to activate it
Manual eSIM installation isn’t as common, but it’s still available with some providers. While it involves more input, the process remains easy and simple:
- Purchase your eSIM plan through the provider’s website or app
- You’ll receive setup details, including an activation code and SM-DP+ address
- On an iOS device, navigate to Settings > Mobile Data and manually enter the information; on an Android device, go to Settings > Network & Internet and select the option to add an eSIM manually
Most providers supply detailed setup instructions. Stick to those steps to avoid issues and activate your eSIM smoothly.
Exact setup steps can vary depending on your device. If you're using a Samsung phone, we've prepared a dedicated guide to help you get started. iPhone users can also follow our step-by-step instructions tailored specifically for Apple devices.
Tips for using an eSIM card for Portugal
Over time, as a frequent traveler, I gathered some tips and tricks for using an eSIM card. Here are a few helpful ones if you’re planning a trip to Portugal:
- Activate your eSIM before landing in Portugal. Activation usually requires an internet connection. Set up your eSIM before leaving for Portugal, or use a Wi-Fi connection upon arrival to complete the process.
- Turn off roaming on your main SIM card. Disabling data roaming on your primary SIM card prevents excessive charges. Surely, you wouldn’t want to pay double for an internet connection.
- Save data by downloading offline maps. To make the most of limited eSIM data, download offline maps before your trip. This lets you navigate without using mobile data – perfect for rural areas or when the signal drops.
- Know how to track your data usage. Keep an eye on your data usage through your eSIM provider’s app or your phone’s built-in settings. This way, you can avoid unexpected limits and adjust your usage before running out.
- Switch between plans or top up with the app. Easily switch between data plans or top up directly through your eSIM provider’s app. With an eSIM, you can connect without needing a physical SIM or visiting a store.
Best eSIM for Portugal: final thoughts
On my trip to Portugal, using eSIMs made staying connected effortless. Setting up ahead of time meant I had data as soon as I landed. I didn’t have to waste time at airport kiosks or hunt for local SIM cards. It made navigating cities, booking rides, and sharing moments way easier than I expected.
Choosing the right eSIM really depends on your travel style. If you’re budget-conscious and mainly sticking to Portugal, a simple, low-cost plan works well. But if you’re hopping between countries or need fast, reliable connections for work or streaming, a more versatile or high-speed option might be better suited for you.
Personally, I’d go with Saily again for its affordability and solid coverage, but Airalo is also a solid pick if you want broader global options. Either way, having an eSIM in Portugal definitely made my trip smoother and less stressful.
