It's highly recommended to activate your EastESIM eSIM before you depart for Kuala Lumpur. Most eSIMs activate upon connecting to a local network, so having it set up pre-arrival means you'll have instant data access as soon as your plane lands at KLIA (KUL), allowing you to book rideshares or navigate immediately.
