What is Lightsim?
What is LightSim?
LightSim is a travel eSIM solution that allows access to mobile data plans in over 211 destinations directly from an app, without having to buy or insert a physical SIM card upon arrival. The eSIM is a digital SIM card embedded in the phone, remotely configurable while offering a similar experience to a traditional SIM. The platform offers several types of plans adapted to different uses: local plans for a single country, regional plans covering multiple destinations on the same route, unlimited data offers, and a pay-as-you-go mode where you pay only for actual consumption. Management is done entirely in the app, with guided installation, consumption tracking, and recharges in seconds. Once the plan is chosen and paid for, the LightSim eSIM installs by following simple steps, then the plan activates automatically when you arrive in the destination country and switch to the eSIM profile in your smartphone settings.
