An eSIM is a digital SIM card built directly into your phone. Instead of inserting a plastic SIM, you install a profile that connects you to a mobile network. With Numero, you can buy and activate a Data eSIM online and start using mobile internet abroad in minutes.

How does an eSIM work?

After you buy a plan, Numero sends you a QR code and manual setup details. You install the eSIM profile on your phone, turn on data roaming for that line when you land, and the eSIM connects to a partner network automatically. Your original SIM stays in place, so you can keep your home number active for calls and SMS.

Can I switch between my physical SIM and eSIM?

Yes. Most modern phones let you keep both lines active and choose which one is used for data, calls, and SMS. You can use your physical SIM for your home number and your Numero eSIM for mobile internet at your destination.

What if my QR code is not working?

Make sure your phone is connected to a stable Wi-Fi network and that the camera is reading the full QR code clearly. If it still does not work, you can install the eSIM manually using the activation details in your Numero account. Our support team is available 24/7 if you need help.

Does the Data eSIM include a phone number?

No. The Data eSIM is a data-only plan. If you also need a local phone number for calls, SMS, or app verification, Numero offers a Full eSIM bundle that combines data, a number, and calling minutes on a single eSIM.

Can I use hotspot with my Data eSIM?

Hotspot support depends on the partner operator, but most Numero data plans allow tethering, so you can share the connection with a laptop, tablet, or another phone.

Can I buy multiple data plans?

Absolutely. You can purchase separate plans for different destinations and switch between them as needed.
