Lisbon with Kids: A Family Guide to the City of Hills

Lisbon is a wonderful, vibrant city for families, but its steep hills and narrow cobblestone streets mean you'll need to plan your transport carefully. To keep everyone happy and moving, combine historic tram rides with a reliable mobile data connection for real-time navigation and ride-sharing apps. Having individual data plans for each family member ensures you can navigate the 'City of Seven Hills' without the stress of hunting for Wi-Fi or tethering to a dying hotspot.

Navigating the Hills without the Tears

Lisbon is famously vertical. While the views from the miradouros (viewpoints) are breathtaking, getting there with a stroller or a tired toddler can be a challenge. The city’s iconic yellow trams, particularly the Number 28, are a hit with children, but they are often packed.

For a more comfortable ascent, look for the city's public elevators and funiculars. The Elevador de Santa Justa is a tourist favorite, but the Elevador da Glória and the Elevador da Bica offer equally thrilling rides for kids. When the hills become too much, ride-sharing apps like Uber or Bolt are incredibly affordable in Portugal. This is where having a dedicated data connection is vital. If you are relying on one person's roaming plan to call a ride while the rest of the family waits in the sun, you’ll quickly realize why we recommend an individual eSIM for every device.

Before you leave the hotel, it is a great idea to consider using Google Maps offline to save data, though you'll still want live data to check the real-time arrival of those famous trams.

Top Family Attractions in Lisbon

Oceanário de Lisboa

Located in the modern Parque das Nações district, this is one of the world's largest and most impressive aquariums. It is a perfect 'rest day' activity because the area is flat—a rare treat in Lisbon. The central tank is massive, housing sharks, rays, and a sunfish.

Pavilhão do Conhecimento (Pavilion of Knowledge)

Right next to the aquarium, this interactive science museum is a haven for kids and teenagers. It’s designed to be hands-on, making it a great place for them to burn off energy while learning. Since the museum offers many digital interactions, having your own data allows the kids to look up more information on the exhibits as they go.

Belém: History and Pastries

A short train or tram ride from the center, Belém is home to the Belém Tower and the Jerónimos Monastery. More importantly for kids, it is the home of Pastéis de Belém. The queue moves fast, and the warm custard tarts are the ultimate reward for a morning of sightseeing. The area is also home to wide-open parks where kids can run freely.

A Day Trip to Sintra

No trip to Lisbon is complete without visiting the fairytale palaces of Sintra. It is about 40 minutes by train. Be warned: Sintra is even hillier than Lisbon. You will need your phone to navigate the bus routes between Pena Palace and the Moorish Castle. Coverage in the lush forests of Sintra is generally excellent on the Vodafone and NOS networks, so you can keep the kids entertained with their favorite apps during the train ride.

Staying Connected: The FamilyRoam Advantage

When traveling with teenagers, the question isn't if they will need data, but how much. In the past, parents often relied on international roaming from US or UK carriers. However, these daily charges add up quickly, especially when you have four or five devices in the mix.

You might be tempted to use one phone as a mobile hotspot. We’ve all been there: "Mom, is the hotspot on?" followed by the inevitable "It’s too slow!" when three people try to stream at once. Hotspotting also drains the host phone’s battery in record time, which is the last thing you want when you're using your phone for navigation.

FamilyRoam offers a better way. By giving each family member their own data-only eSIM, everyone gets their own slice of 5G bandwidth. You can see plans that range from small 1GB weekly top-ups to massive 50GB monthly buckets, ensuring even the most data-hungry teen is satisfied.

Local Carrier Realities in Portugal

Portugal has excellent mobile infrastructure. When you use a FamilyRoam eSIM, your device will typically connect to Vodafone or NOS. Both carriers offer extensive 5G coverage in Lisbon, Porto, and the Algarve.

• Cities: In Lisbon, you can expect 5G or strong 4G+ almost everywhere, including inside the thick stone walls of many historic buildings.
• Rural Areas: If you’re heading to the Alentejo countryside or the mountains of the Serra da Estrela, coverage remains reliable, though it may drop to 4G.
• Airport Arrival: Don't waste your first hour in Portugal standing in line at a Vodafone kiosk at Lisbon Portela Airport (LIS). By the time you’ve cleared customs, your FamilyRoam eSIM can already be active, allowing you to call a ride or check the Metro map immediately.

Connectivity Comparison for Families

Feature	US/UK Carrier Roaming	Local Physical SIM	FamilyRoam eSIM
Setup	Automatic (but expensive)	Manual (find a shop)	Digital (instant)
Cost	High daily fees per device	Low, but inconvenient	Affordable & flexible
Number	Keeps your home number	Local Portuguese number	Data only (no number)
Multi-Device	Difficult to manage	One SIM per person	Easy to buy for everyone
Network	Throttled roaming	Local 5G	Local 5G (Vodafone/NOS)

Technical Setup for Parents

Setting up an eSIM is simpler than it sounds. Most modern phones, including the iPhone 11 and newer or the Samsung Galaxy S20 and newer, support eSIM technology. You can check if your phone is compatible before you buy.

Step-by-Step Installation

1. Purchase: Choose your plan and see plans for the duration of your trip.
2. QR Code: You will receive a QR code via email.
3. Scan: On an iPhone, go to Settings > Cellular > Add eSIM. On Android, go to Settings > Network & Internet > SIMs > Add.
4. Label: Label the new line "Portugal Data" so you don't confuse it with your primary line.
5. Data Switching: Ensure "Cellular Data Switching" is off to avoid accidental roaming charges on your home SIM.

For a more detailed walkthrough, see our guide on how to get started with travel eSIMs. One common concern for parents is whether they can still use their home apps. Since these are data-only plans, you won't get a local Portuguese phone number, but you can still use WhatsApp, FaceTime, and iMessage with a travel eSIM just like you do at home.

Managing Data Usage on the Road

Lisbon is a very "Instagrammable" city, and your teens will likely be uploading photos and videos constantly. If they are playing games during long dinners or transit, keep an eye on their usage. For example, if your kids are into gaming, you might be surprised by the Minecraft Multiplayer Data Usage over a week of travel.

FamilyRoam makes it easy to top up. If a 3GB plan runs out because someone spent too long on TikTok at the Praça do Comércio, you can simply add more data through the website without needing to swap physical cards.

The bottom line

Lisbon is a magical city for families who are prepared for its unique geography. By equipping every family member with their own 5G data plan, you eliminate the "hotspot wars" and ensure that everyone has the tools they need to explore safely. From the depths of the Oceanário to the heights of Sintra, staying connected allows you to focus on making memories rather than fixing connection issues.
