Home line, Travel eSIM, Data switching: choose by your route, party and the exact product conditions.
Compare at a glance
| Option | Best fit | Check before booking |
|---|---|---|
| Home line | Existing phone-number services | Roaming and carrier charges |
| Travel eSIM | Local mobile data | Selected data line and settings |
| Data switching | Backup behaviour | Prevent unintended home-line use |
Choose the option that fits your journey
Decide which line should provide data and which should remain available for your existing number. Review the home carrier’s overseas charging conditions before enabling services. Receiving an important message and using mobile data are different needs; the presence of two lines does not automatically choose the right line for each.

Use the linked operator or seller information for your travel date. Save the selected product, address or meeting point and the terms that apply to your party. Source review dates are separate from publication dates: an English edition is not a claim that a price or service remains unchanged. Leave a practical margin before any fixed onward departure.
