Roaming in the European Union has been free since 2017. But just a few kilometers outside that zone, things change fast.

Andorra is one of those places.

It may look like a convenient ski escape between Spain and France, but when it comes to mobile connectivity, it behaves more like a completely separate telecom market. And that can get expensive very quickly.

In extreme cases, mobile data in Andorra can cost up to €15,000 per GB, depending on your operator and whether you have a roaming plan.

If you’re heading there without preparing, your phone bill can easily cost more than your trip.

Why roaming is so expensive in Andorra

The key reason is simple: Andorra is not part of the European Union.

That means EU roaming regulations do not apply. Operators are free to charge whatever they want, and they often do.

Unlike larger countries, Andorra has only one telecom operator: Andorra Telecom, which is state-owned. With no competition and a small market, prices remain high.

You might assume that French or Spanish networks would cover the area. While their signals sometimes reach across the border, they are weak and unreliable. In practice, your phone will connect to Andorra Telecom’s network, and that is where the high charges begin.

What does data actually cost?

Without a roaming package, data prices can be extreme.

Many operators charge over €10 per MB. That means:

• Sending a short WhatsApp video can cost around €30
• Browsing for a few minutes can cost hundreds of euros
• Streaming or background data usage can quickly reach thousands

This is how those shocking €15,000 per GB scenarios happen. Not because people intentionally use that much data, but because phones consume data in the background without you noticing.

Calls and SMS are not much better

It’s not just data.

Making calls from Andorra can cost close to €2 per minute, and in many cases, you are charged for incoming calls as well.

Simply answering a call can add unexpected costs to your bill.

Local SIM option: Andorra Telecom

Andorra Telecom offers its own prepaid SIM, called Mobiland.

You can get 2G, 3G, and 4G coverage, and the signal quality is generally strong within the country.

The SIM typically costs around €30, including credit, although promotional pricing may lower that to around €15.

Buying a SIM is straightforward. You only need a passport or national ID, and you can find them in:

• Official telecom stores
• Supermarkets
• Petrol stations
• Tobacconists
• Pharmacies
• Andorra–La Seu d’Urgell Airport

This is a decent option if you are staying for several days and want stable connectivity.

Roaming bundles: a safer alternative

Many operators, especially smaller or “low-cost” brands, now offer dedicated roaming bundles for Andorra.

A common structure looks like this:

• Around €9 per day
• Includes up to 3 GB of data
• Automatically activates when you connect to the Andorra network

This is significantly cheaper than standard roaming, but it still comes with limitations.

You pay the daily fee even if you use very little data. And if you exceed the included allowance, a new package is triggered automatically.

Still, compared to default roaming rates, this is often the safest option.

The biggest mistake travelers make

The biggest issue is not heavy usage. It is passive usage.

Smartphones constantly use data in the background. Apps update, emails sync, and cloud services run silently.

If you enter Andorra with mobile data turned on, your phone will start consuming data immediately, even if you never open a browser.

That is how people end up with massive bills.

How to avoid a roaming shock in Andorra

There are a few simple ways to stay safe:

• Turn off mobile data before entering the country
• Check your operator’s roaming pricing in advance
• Activate a roaming bundle if available
• Consider buying a local SIM for longer stays
• Use Wi-Fi whenever possible

If you want complete control, switching to an eSIM plan designed for travel is often the most predictable option.

Final takeaway

Andorra is a perfect example of why roaming is not “solved” globally.

Inside the EU, connectivity feels seamless. Step outside, and the old risks return immediately.

The difference is that today, you have more options. Local SIMs, roaming bundles, and eSIMs all give you ways to stay connected without taking unnecessary risks.

But the key is simple: do not arrive unprepared.

Because in Andorra, your phone bill can escalate faster than your ski lift.
