eSIM is the latest technology for mobile devices that will ultimately remove the need for physical SIM cards. ‘eSIM’ refers to an embedded SIM and takes the form of a chip that cannot be removed from a mobile device. This means that users can switch between mobile networks without needing to replace their SIM card.

Users can download “profiles” from different networks straight to a mobile device with the touch of a button. An eSIM performs the same function as a physical SIM card but removes the requirement to physically swap SIMs when switching between network providers.
