About LightSIM
LightSIM sells four kinds of plan: fixed-volume local and regional bundles, unlimited plans for chosen destinations, pay-as-you-go data, and a worldwide eSIM installed once and reused on later trips. Validity begins on arrival rather than at purchase, and current plans can be refreshed in the app without reinstalling. Unlimited hotspot use is advertised, and the service is built by the telecom provider Telexchange.
