Globally Connected with eSIM: The Future of Travel Connectivity Starts Now
The traditional physical SIM card is becoming obsolete – the future is called eSIM. With vintrica, you can now book not only your digital toll sticker (E-Vignette) but also eSIMs for over 100 countries worldwide – ideal for your next trip.
But what exactly is an eSIM, how does it work, and what advantages does it offer, especially when travelling? In this article, you’ll find everything you need to know about eSIM technology.
What is an eSIM?

The term eSIM stands for “embedded SIM” – a SIM card that is permanently integrated into the device. Unlike traditional SIM cards (Mini, Micro or Nano), which need to be manually inserted into a device, the eSIM is already built in as a chip and can be digitally “programmed” with a mobile network profile.
A physical card is therefore no longer necessary – activation usually takes place by scanning a QR code or via the mobile provider’s app.
How Does an eSIM Work?
The eSIM is permanently integrated into your device but works technically just like a regular SIM card. With our eSIMs, your personal phone number remains the same, so you can still be reached as usual. In addition, you can use the data plan you’ve chosen while abroad.
Activation in 3 Simple Steps:
-
Use an eSIM-compatible device (e.g. newer iPhones, Android phones, tablets or smartwatches)
-
Order your eSIM (add it during the vignette purchase process or via our partner site heyroamio.com)
-
Scan the QR code and activate your eSIM

The eSIM offers many practical advantages – especially for travellers:
-
No need to swap cards – the eSIM is easily activated via QR code.
-
Store multiple eSIM profiles – ideal for separating personal and business tariffs.
-
Perfect for travel – simply activate a local prepaid eSIM while abroad and save on roaming charges.
-
Improved security – eSIMs can’t be physically removed, for example in the event of theft.
What should you keep in mind when using an eSIM?
To make the most of the benefits an eSIM has to offer, it’s important to ensure your device is compatible. Not all smartphones, tablets or wearables support eSIM technology – this is especially true for older models. Checking the technical specifications or the manufacturer’s website will quickly provide clarity.

The eSIM represents a new kind of mobile connectivity – straightforward, digital, and ready to use at any time. It not only makes switching tariffs easier and saves space within the device, but also offers real added value when travelling: local prepaid data plans can be activated with ease – no waiting, no physical SIM card required.
Anyone using an eSIM-compatible device stays flexible around the world, saves on roaming charges, and enjoys a significantly more convenient user experience – whether on a business trip or holiday.
