FAQ

For a city trip or a week in Europe, it is recommended to choose a regional Europe plan with a data volume suited to your use (5 to 10 GB is generally sufficient for browsing, social networks, and GPS). If you need calls or SMS, opt for a “full eSIM” plan.

Yes, tethering (hotspot) is generally allowed with Numero eSIM. However, this may depend on the local partner network and the specific conditions of your plan. It is advisable to check your plan details and test the functionality once on site.

Numero eSIM is compatible with most recent smartphones equipped with eSIM technology, such as iPhones (from iPhone XS/XR), Google Pixel (from Pixel 3), and many Samsung Galaxy models. You can consult the full list of compatible devices on the official website or within the Numero app.

Refund policies vary. In case of a proven technical problem that cannot be resolved by support, you may be eligible for a refund. It is essential to contact Numero eSIM customer support immediately after detecting the issue. For purchases made via the App Store or Google Play, the refund terms of these platforms apply.

Yes, most smartphones with dual SIM capability (physical and eSIM) allow simultaneous use of your physical SIM card for usual calls and SMS and the Numero eSIM for mobile data abroad. This lets you stay reachable on your usual number while benefiting from advantageous data rates.

The Numero eSIM app allows you to monitor your data usage in real time. It is recommended to check it regularly to manage your consumption and avoid surprises. The app can also send alerts if your data balance is low.
