What is an eSIM?
An eSIM is a digital SIM built into your device. It allows you to activate a mobile data plan without inserting or replacing a physical SIM card.
How does an eSIM work?
An eSIM works like a traditional SIM card, but the mobile network profile is downloaded directly to your device. After purchasing an eSIM plan, you normally receive a QR code or installation details. Your phone uses this information to download and activate the eSIM profile.
How to start using an eSIM
- Choose an eSIM plan for your destination.
- Receive your QR code or installation details.
- Open the mobile network settings on your device.
- Add the eSIM and complete the installation.
- Activate mobile data when you are ready to connect.
Why is an eSIM useful for travel?
A travel eSIM can give you mobile internet shortly after arriving at your destination. You can install it before departure, keep your primary SIM in the phone and avoid searching for a local SIM card at the airport or in a shop.
Main benefits of using a travel eSIM
- Quick digital installation
- No physical SIM card replacement
- Install before your journey
- Keep your primary SIM in the device
- Use maps, messages and travel apps abroad
- Choose a data plan that matches your trip
- Switch between installed mobile plans
Can I use an eSIM and a physical SIM together?
Many compatible phones support Dual SIM functionality. This means you may be able to keep your usual SIM active for calls and messages while using the travel eSIM for mobile data. The available options depend on your device model and mobile network.
Does an eSIM change my phone number?
A data-only travel eSIM normally does not replace your existing phone number. Applications such as WhatsApp can usually continue using the number already registered in the application, even when mobile data is provided by the eSIM.
Which devices support eSIM?
Many recent smartphones, tablets and smartwatches support eSIM technology. Compatibility varies by manufacturer, model, country of purchase and carrier restrictions, so you should always check your exact device before buying a plan.
Is an eSIM secure?
An eSIM is stored digitally inside the device and cannot be physically removed like a traditional SIM card. Installation details and QR codes should still be treated as private information and should not be shared with other people.
When should I install my travel eSIM?
You can usually install the eSIM before your journey while you have a reliable internet connection. Some plans begin when they first connect to a supported network, while others may begin immediately after installation. Always check the activation conditions of the selected plan.
