Getting Started
Understand eSIM basics and prepare your Wanderly plan before you travel.
A travel eSIM is easiest when you prepare it before departure. Start by checking that your phone supports eSIM and is carrier-unlocked, then choose a plan for your destination. Check when validity starts and where installation is allowed before installing over reliable Wi-Fi.
These guides explain when a plan starts, how your primary SIM works alongside it, and which settings to change after you arrive.
