We recommend installing your eSIM ProZone prior to your flight to the USA. Having an active internet connection upon arrival is highly beneficial. It allows you to communicate with contacts immediately after landing and can facilitate a smoother entry process, for example, by using the Mobile Passport Control (MPC) app, potentially reducing wait times at US Customs and Border Protection (CBP).
