What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card that's built directly into your smartphone, tablet, or smartwatch. Unlike traditional physical SIM cards that you insert into your device, an eSIM is a programmable chip that allows you to activate a cellular plan without needing a physical card. This technology makes it incredibly easy for travelers to get connected instantly across Southeast Asia without having to find local stores or deal with tiny SIM card trays.
