Best eSIM for Europe 2026 — Australian guide
One eSIM for all of Europe — no SIM swapping required
Europe is a continent of 44 countries, and Australians love exploring it. Whether you're doing a classic grand tour through France, Italy, Spain and Greece, or focused on one region, staying connected across borders used to mean buying a new SIM card every few countries.
A Proost Europe eSIM covers 30+ countries on a single plan. Cross from France into Italy, Switzerland into Germany, or Greece to Croatia — your data just keeps working.
Which countries are covered?
The Proost Europe plan covers all major European destinations including France, Germany, Italy, Spain, Portugal, Greece, Netherlands, Belgium, Switzerland, Austria, Czech Republic, Poland, Croatia, Hungary, and many more.
Why not just use Telstra or Optus roaming?
Australian carrier roaming in Europe costs $10–$15 per day per country. For a three-week European trip across five countries, you could be looking at $200–$300 in roaming charges — before you've spent a cent on anything else.
A Proost Europe eSIM gives you a fixed data budget at a fraction of the cost.
How does a multi-country eSIM work?
When you cross a border, your phone automatically connects to the local network in that country. No settings to change, no new SIM to buy. The eSIM handles it seamlessly.
How much data do you need for Europe?
School holidays and peak season
The Australian school holidays in July align with peak European summer travel season. Book accommodation and transport early, and sort your eSIM before you leave so you're not scrambling for wifi at Charles de Gaulle.
