Laptop Internet in Europe: One eSIM, Every Country

Europe is made for multi country trips, which is exactly where a single eSIM shines. Here is how to keep your laptop online across the continent.

To keep a laptop online across Europe, use one Citrus Mobile eSIM on your phone and tether the laptop, or install it directly on a cellular laptop. It works across 40+ European countries on a single balance, switching to a strong local carrier automatically as you move between them, all pay as you go from $4.

Why Europe is perfect for one eSIM

A European trip often touches several countries in a single week. Paris to Brussels to Amsterdam, or a rail loop through Italy, Austria, and Switzerland. Buying a local SIM in each one is a waste of time, and roaming across them can stack up fees. A Citrus Mobile eSIM covers 40+ European countries on one balance and switches to a strong local carrier automatically as you cross each border, so your laptop simply stays online. Browse the full list and rates on the Europe eSIM hub.

Coverage across the continent

The eSIM works throughout the major destinations and the smaller ones in between, including the United Kingdom, France, Germany, Italy, Spain, and many more. Europe generally has excellent 4G and strong 5G in cities, so a tethered laptop performs well for video calls, uploads, and a full day of work. Check any specific country on the rates page.
