We strongly recommend activating your eSIMFlyer before your flight to the USA. Having an active data connection upon landing is a game-changer for international arrivals. Long queues at US Customs and Border Protection (CBP) are common, and with eSIMFlyer, you can immediately communicate with family, access the Mobile Passport Control (MPC) app to potentially expedite your entry, or check ground transportation options while still on the tarmac. It ensures you're connected the moment you touch down.
