NubesSIM is a travel eSIM service that gives you affordable mobile data in 200+ destinations worldwide — no roaming fees, no physical SIM cards. Just install the eSIM and connect instantly.

We recommend installing it on the day of your travel to ensure a smooth connection once you arrive. A stable internet connection is required during installation.

An eSIM (embedded SIM) is a digital SIM card that's built directly into your device. Unlike a traditional SIM card, you don't need to insert a physical card - you can install and activate it digitally.

Yes, you can share your eSIM data with other devices using the mobile hotspot feature.

You can transfer it before activation. Once the eSIM is installed, it cannot be moved to another device.

Make sure you are in the destination country, data roaming is turned on, and the Nubes eSIM is selected as your active data line. Try toggling Airplane Mode on and off, or manually selecting a network if needed. Check your APN settings. If the issue still persists, please contact Support.

Nubes eSIM is a data-only service and does not include calls or SMS. You can still make calls and send messages using apps like WhatsApp, FaceTime, Skype, or other internet-based services.
