Find your place

Choose your destination

Search for the country or region you're visiting and explore the available travel data options.

Choose what fits

Compare and select a plan

Check the data allowance, validity period and coverage. When ready, choose the option that suits your trip.

Set up on your phone

Install your eSIM

After purchase, use the installation details supplied with your plan. You may be asked to scan a QR code or enter details manually, preferably over Wi-Fi.

Enjoy the trip

Connect when it's time

Follow the plan's activation guidance, then select the travel eSIM for mobile data. Enable data roaming on that eSIM only if instructed by your provider.

Important: Installation and validity start times differ between plans. Always follow the specific instructions for your eSIM, especially before travelling.
