eSIM

A digital SIM built into your phone that replaces a physical SIM card, activated by scanning a QR code instead of inserting plastic.

eSIM (embedded SIM) stores your mobile carrier profile on a chip already built into your phone, rather than on a removable plastic card. For Kenya travel, this means you can buy and install a Kenya data plan before you leave home, activate it the moment you land, and keep your home SIM in place for calls and texts — all without visiting a shop or swapping cards.
