An eSIM is an embedded SIM. Like a physical SIM card, an eSIM from Koodo allows you to connect to the Koodo mobile network.
An eSIM voucher contains a digital SIM that lets you access a cellular plan without having to insert a physical SIM card. This eSIM voucher also allows you to use up to two phone numbers on select smartphones.
An eSIM voucher can't be inserted or removed.
