Planning a romantic weekend in Paris? Or maybe an adventurous road trip through Spain and Portugal?
Whatever your idea of the perfect vacation, staying connected is essential!
But how does roaming in Europe actually work these days? And what are the alternatives to the costly rates charged by traditional operators?
In this guide, we’ll explain everything you need to know about Europe SIM cards and how eSIMs can make your travels, and your life, much easier.
What is roaming?
Roaming is a service that allows your smartphone to connect to foreign mobile networks while you’re abroad, using partner networks from other operators.
While it’s incredibly useful and convenient, it can also come with sky-high costs! Your home mobile operator typically applies extra charges when you use your usual SIM to connect abroad.
Roaming in Europe: What’s changed?
Since 2017, the European Union introduced the “Roam Like at Home” policy, which allows EU citizens to continue using their domestic data plan in other EU countries with no extra charges… but is it really as good as it sounds?
In reality, each operator can impose “fair use” limits, meaning once you exceed a certain data threshold (sometimes just 1 GB!), they might (read: almost certainly will) apply extra fees.
Some providers also enforce stricter rules if you travel often or for long periods.
So yes, you can use your domestic data plan within Europe, but only under specific conditions, and these vary from one provider to another.
As soon as you arrive abroad, you’ll usually receive a text message outlining what’s included for free, along with the overage charges once you go beyond those limits.

Common issues with traditional roaming
Despite the EU regulations, traditional roaming still presents a number of issues that make it far from ideal:
- High costs outside the EU
- Contracts and unclear fine print
- Slow or unstable connections
- Difficulty tracking your actual data usage
Many travelers burn through their “Roam Like at Home” data much faster than expected, sometimes losing all credit just from using Google Maps!
