  2. 02

    Install within 24 hours before departure

    Usually install within 24 hours before departure over stable Wi-Fi. Once delivered, use quick installation, a QR code or manual details from your order or “My eSIMs”. Billing starts according to the selected plan.

  3. 03

    Set your data line and activate as instructed

    In a covered region, select the eSIM for mobile data and enable roaming as required. Complete any scheduled or manual activation. Successful installation does not necessarily start the validity period.

How to choose data and validity

These starting suggestions assume a 5–7 day trip. Actual usage depends on video, photo uploads and hotspots. Choose validity covering every day from arrival to departure; available allowances are shown in the plan list above.

Light use · 5 GB total

For a 5–7 day trip mainly using maps, messaging and itinerary checks, with hotel Wi-Fi, consider 5 GB total. This is shared across the full validity period, not 5 GB per day.

Everyday travel · 2 GB per day

For daily navigation, social media and photo uploads, consider 2 GB per day. For a 7-day trip, choose a 7-day daily 2 GB plan and check its daily reset time.

Video and hotspots · from 20 GB

For frequent video, video calls or laptop tethering on a one-week trip, compare total-data plans from 20 GB. Choose more for longer trips or heavier video use, and confirm hotspot support.
