Picture this: you’re sipping an espresso at a street café in Florence, uploading photos to your story, replying to messages, and checking directions for your next stop. You’re connected and can actually relax. That’s because you’re still within the EU, where your mobile data works just like it does at home.

Now imagine you’re somewhere else, like Thailand or the US. Same phone, same apps, same habits — but this time your plan doesn’t include free roaming. When the bill arrives, the shock is real.

Roaming rules can either keep your trip smooth or turn into an expensive mistake. This guide will help you understand how things work in the EU and beyond, and how to stay connected without overpaying.

What Is Roaming and How Does It Work?

Definition and basics

Ever wondered how your phone still works when you’re abroad? That’s thanks to roaming. When your mobile connects to a network outside your home country, your usual provider makes an agreement with a local one so you can stay connected.

Roaming is convenient, but it often comes at a cost. Your provider pays the foreign network to provide service, and then charges you for using it. That can lead to high costs for calls, texts, and especially data, depending on where you are.

Now that we’ve covered the basics, let’s look at why roaming within the EU is much more affordable than in other parts of the world.

The “Roam Like at Home” Policy in the EU

What it means for travelers

If you’re traveling anywhere in the EU, plus Norway, Iceland, or Liechtenstein, you can use your mobile plan just like at home. There are no extra fees for using your regular calls, texts, or data. Whether you’re posting from Paris or navigating Naples, you’re covered.

Fair use policy and data limits

There are limits, though. The EU’s “fair use” policy prevents long-term roaming. If you spend more time abroad than at home over a few months, your provider might apply a small fee. Unlimited or very cheap data plans may also come with a cap on how much data you can use abroad. For example, someone on a €13/month plan should get at least 20 GB to use in other EU countries. Once you go beyond that, you’ll pay a regulated fee per GB.

How to check if your plan includes roaming

Before you go, check if your plan includes roaming. Most providers make this easy through their websites or apps. Look for roaming settings, available data, and whether anything needs to be activated ahead of time.

Of course, not every trip is by train or car. What if you’re flying or taking a cruise? That’s where things get tricky.

Can I Roam While Travelling by Ship or Plane?

Roaming on ships and planes is not covered by EU protections. These connections usually rely on satellite networks rather than traditional cell towers. As a result, they can be extremely expensive, often charging several euros for a single megabyte of data.

To avoid surprise costs, turn on airplane mode or disable roaming as soon as you board. Some phones also allow you to block satellite networks or limit background data when roaming.

Now let’s look at what happens when you step outside EU borders, where the rules can vary even more.

Roaming Outside the EU: Costs and Common Practices

Countries with special agreements

Once you’re outside the EU, the situation depends on where you go. Some countries have special agreements, while others don’t.

• UK: Since Brexit, roaming depends on your provider. Some still offer it for free, others charge extra.
• EEA countries: Norway, Iceland, and Liechtenstein follow EU rules.
• Western Balkans: Some mobile plans include reduced rates or free roaming in countries like Serbia or Montenegro.

Examples of roaming charges in popular non-EU destinations

Here’s a rough idea of what you might pay without a roaming plan:

• Turkey: Usually not covered. Expect to pay around €7 per day or €0.10 per MB.
• Switzerland: Not part of the EU or EEA, so roaming fees depend on your provider.
• USA: Some plans offer €5 to €7 daily roaming packages that include calls, texts, and limited data.
• Thailand: Data can be expensive without a package. A 500 MB roaming pass might cost €6 to €10.

To avoid draining your wallet, here are some smart ways to manage mobile internet when traveling.

Tips to Control Mobile Internet Costs When Traveling

Check your operator’s roaming packages

Many providers offer daily or weekly bundles for roaming. These are often much cheaper than using standard rates. You can also set a spending limit, which many providers cap around €50 by default.

Use Wi-Fi wisely

Wi-Fi is your friend, especially in hotels, airports, and cafés. Just remember to be cautious on public networks. Avoid logging into banking apps or entering personal details unless you’re using a VPN.

Consider local SIM cards or travel eSIMs

If you’re going to be away for a while or expect to use a lot of data, look into buying a local SIM card or travel eSIM. These usually offer better rates and can be activated easily through apps without swapping your main number.

Turn off background data and updates

Apps often run in the background, using data without you noticing. Turn off automatic updates and background syncing. You can also restrict mobile data usage in your phone’s settings.

Final Thoughts

Roaming in 2025 is straightforward if you’re traveling within the EU. Beyond that, it gets more complex, but a little research can go a long way. Take a few minutes to understand your plan, check what your provider offers, and make small changes to your phone settings. It’s a simple way to stay connected and avoid an expensive surprise when you get home. Safe travels!
