What is eSIM?
An eSIM is a programmable SIM pre installed in the device at manufacturing. Instead of inserting or swapping a physical card, you download a carrier profile digitally. That frees up space in the device and makes switching carrier easy.
How eSIM works
- Built in, the eSIM is already in your device, managed electronically.
- Digital activation, you usually scan a QR code from the operator to load a profile.
- Multiple profiles, useful for frequent travellers who add a local profile abroad.
- Remote programming, you can change operator without visiting a store.
- Security, profiles and data are encrypted.
eSIM, smartwatches and IoT
With eSIM a smartwatch can have its own connection without being tethered to a phone. The technology also plays a key role in the Internet of Things, where connected cars, sensors and machines can each have their own connection via eSIM.
