What is an eSIM? How the digital SIM card works

An eSIM (embedded SIM) is a SIM built permanently into the device: instead of inserting a plastic card, your mobile operator loads its profile onto the chip over the internet. It is based on an open GSMA standard, works in every mainstream network just like a conventional SIM card, and can be set up with a QR code, an app or directly from your old phone.
