Wie funktioniert eine eSIM im Ausland?

How does an eSIM work abroad?

What is an eSIM and how does it work technically?

An eSIM, short for "embedded SIM", is basically a digital chip that is integrated directly into your smartphone. Unlike a conventional plastic SIM card that you physically insert into your device, the eSIM is already built in.

How does activation work?

  • QR code: When you buy a new eSIM, you usually receive a QR code. You simply scan this with your smartphone's camera.
  • eSIM profile: Alternatively, you can download the eSIM profile directly and install it on your device.
  • Activation: Your smartphone reads the information from the eSIM and sets up a new mobile connection.

What happens in the background?

  • eUICC: Inside the eSIM there is a universal integrated SIM card (eUICC). This can store multiple eSIM profiles.
  • SM-DP+: A so-called "Subscription Manager Data Provisioning" (SM-DP+) is responsible for managing the eSIM profiles. It communicates with your mobile phone provider and ensures that you always have the right settings.

Advantages of an eSIM compared to the traditional SIM card

  • Flexibility: You can store multiple eSIM profiles on one device and switch between them without having to physically replace the SIM card.
  • Security: Since the eSIM is permanently connected to the device, the risk of loss is lower.
  • Future-proof: eSIMs are the future of mobile technology and offer many new possibilities, such as integration into IoT devices.
  • Environmentally friendly: By eliminating the physical SIM card, less plastic waste is produced.

eSIM abroad: It's that easy

  1. Choosing the right tariff: Choose a tariff that suits your travel destinations and usage behavior.
  2. Purchasing the eSIM: Order your eSIM online from a provider like VOISIM.
  3. Activation: Scan the QR code or download the eSIM profile and follow the instructions on your device.
  4. Usage: Once the eSIM is activated, you can use your smartphone as usual.
