Is it advisable to activate my WorldESIM before clearing US Customs and Border Protection?

We highly recommend activating your WorldESIM before your flight or upon landing, prior to engaging with US Customs and Border Protection (CBP). Having immediate internet access is incredibly beneficial. It allows you to communicate with waiting family or friends, access crucial travel documents, or utilize mobile apps like Mobile Passport Control (MPC) to potentially expedite your entry process. This proactive step ensures you’re connected from the moment you touch down, streamlining your arrival into the United States.
