A friend of mine once paid €70 in roaming charges over one weekend. I had warned her, but she forgot when she crossed the border. Many people assume Andorra is in the European Union and that being next door means roaming is included. It is not, and charges can add up quickly.
Important exception: Some operators include Andorra in their plans. For example, Bouygues Telecom in France includes it by default on selected plans. Other Spanish or French operators may do so too, so check your plan before travelling.
To avoid roaming surprises and get online easily, an eSIM is the most convenient option. For under €5 you can get data for a week without needing to search for Wi-Fi.
Free Wi-Fi is also available in the centre and at ski resorts, but it has limitations.
⚡ Quick answer: Saily (US$4/1 GB/7 days) for short trips, Andorra Telecom (€10/30 days) for longer stays. Free Wi-Fi is available in the centre, but it is not the most convenient way to explore.
✈️ Saily eSIM: convenient for short trips
My first recommendation is an international eSIM, such as Saily. I use it when travelling between several places.
An eSIM is an electronic SIM installed on your phone. It lets you use mobile data like a physical SIM without inserting a card.
The cheapest option is US$4 for 1 GB over 7 days, which should be enough for most visitors, especially if you use your hotel Wi-Fi.
Setup is simple: scan the QR code sent by email and you are ready to go. It works across Andorra, including Grandvalira and Vallnord (Pal-Arinsal). It is compatible with iPhone XS and later, Samsung Galaxy S20 and later, Google Pixel 3 and later, and most recent phones.
The plan is data-only and does not include regular calls. Calling a taxi or someone who does not use WhatsApp can be less convenient, but this is not a problem for most people who use internet calling.
What about Holafly?
Holafly has similar plans. I know Saily better, which is why I recommend it, but Holafly is also a good option if you already use it.
🇦🇩 Andorra Telecom eSIM: the local option
Andorra Telecom, Andorra's phone company, recently launched eSIMs. There are two options:
- Day eSIM: From €5 for 3 GB over one day. It costs more than Saily and is mainly useful for a very short visit, such as a weekend.
- Prepaid SIM/eSIM: From €10 for 30 days, including data and calls. A better option for stays of a week or longer.
The €10 plan for 30 days is the most interesting option if you need local calls for taxis or restaurants. As Andorra's official operator, it also offers strong coverage, including in mountain areas.
💡 Tip: If you are staying more than a week or need to make local calls, Andorra Telecom is a good choice for price and coverage.
📶 Can you get by using only free Wi-Fi?
Free Wi-Fi is available in Andorra, but it has important limitations.
Wi-Fi in central Andorra
Central Andorra la Vella has a public network called “Andorra WiFi” covering the shopping area, especially Avinguda Meritxell and Carlemany.
But it has limitations: it disconnects when you enter shops, requires registration, and does not work on the road or help you find your hotel when you arrive. It is fine for sending a WhatsApp while sitting on a bench, but not convenient for exploring.
Wi-Fi at ski resorts
Ski passes include Wi-Fi access. At Grandvalira, connect using the code on your pass.
How to access Grandvalira Wi-Fi
- Connect to the “Grandvalira WiFi” network.
- Register by completing the form that appears.
- Enter the Wi-Fi code printed on your ski pass.
- Verify your email address within 60 minutes.
Wi-Fi access is unlimited for the duration of your pass. See the official information →
When free Wi-Fi is not enough
There is no Wi-Fi on the road. From the border until you reach your hotel, you are offline. If you need GPS to find your accommodation or parking, free Wi-Fi will not help.
It is also harder to stay connected in the mountains. For under €5, you can get data for the week instead of having to search for Wi-Fi whenever you need it.
💡 Tip: If you decide to use only free Wi-Fi, download Google Maps offline before arriving in Andorra.
Public Wi-Fi safety
Make sure you connect to the correct network name, not a similarly named one. Fake networks can be used to steal passwords.
Modern websites are generally safer. WhatsApp uses end-to-end encryption, so someone capturing the traffic cannot read your messages. Most modern websites use HTTPS (look for the lock icon in your browser), which encrypts traffic to the server.
Even so, avoid making payments or entering sensitive banking details on public Wi-Fi. For banking or online shopping, wait until you have a trusted connection.
💳 Physical SIM: mainly for a temporary local stay
Andorra Telecom also sells physical SIM cards in its shops. The initial kit costs €30 and includes credit; the minimum top-up is €15.
You need to visit a shop, queue and set up the SIM in person, so it only makes sense if you live or work here temporarily for weeks or months. For a regular holiday, an eSIM is better because you can buy it from home and save time.
✅ Conclusion: eSIM for convenience, free Wi-Fi to save
If you want to explore without constantly looking for Wi-Fi, an eSIM is your best option for under €5.
First check whether Andorra is included in your mobile plan. If not, use Saily eSIM for a short trip (from US$4/1 GB/7 days), or Andorra Telecom eSIM for a longer stay (€10/30 days with calls).
Free Wi-Fi in the centre and at ski resorts can work if you want to save money, but download offline maps and be prepared to have no internet on the road.
Most importantly, turn off mobile data when you arrive in Andorra. This helps avoid bill surprises like the €70 my friend paid.
