What is eSIM and how does it work?
eSIM (embedded SIM) is a digital SIM card built directly into your device. Unlike a traditional plastic SIM card, you don't need to physically insert or replace it. It represents the most modern way to connect to mobile networks worldwide.
Basic principle of eSIM operation
eSIM works on the same principle as a classic SIM card, but in digital form:
- Contains a chip built directly into your device
- Downloads profiles of mobile operators remotely via the internet
- Allows storage of multiple different profiles simultaneously
- Enables switching between operators without physically changing cards
When you purchase a data eSIM, the provider sends you a QR code or activation details. After scanning or entering them, the corresponding profile is downloaded to your device and you can immediately use the mobile services of that operator.
