What does “convert to eSIM” mean?
“Convert to eSIM” means switching from your existing physical SIM card (found in a little slot on the side of your device) to an eSIM (embedded SIM).
An eSIM works the same way as a physical SIM, except there is no physical component to it — it is a downloadable version of a SIM card.
Most smartphones these days support eSIMs, and many offer dual SIM capabilities, meaning you can keep your phone number and plan, while simultaneously using an eSIM for affordable mobile data while travelling.
