Roaming, SIM or eSIM: choose for your actual trip

Start with your phone and the functions you need, not the product name. Prepare for arrival and for meeting your guide.

Check compatibility and activation

Confirm eSIM compatibility and any carrier lock with your device information and mobile provider. Check the product's installation, start time, validity and supported countries, then complete the necessary preparation before departure.

Separate data from calls and texts

A data-only product may not include voice calls or SMS reception. If you need verification texts on your usual number, check overseas reception and charges with your carrier, and decide whether you need app contact, regular calls or both.

Consider how your group will connect

Check hotspot support, speed after the allowance, top-ups and support for each product. Rather than relying on one person's connection, agree on contact methods and a meeting place if the group separates.

Be ready to meet without the internet

Save your accommodation address, station exit and agreed guide meeting place and time as screenshots or offline notes. Check your battery before leaving and use your agreed meeting and contact plan if the connection fails.

Check the official guidance

Entry requirements, opening hours and prices can change. Recheck the official guidance before departure.
