We strongly recommend activating your DataESIM prior to your flight or immediately upon landing, before reaching the CBP checkpoint. Given that wait times for US Customs and Border Protection (CBP) can be extensive, having an active internet connection allows for immediate communication with contacts or the efficient use of digital tools like the Mobile Passport Control (MPC) app. This proactive activation streamlines your entry process and ensures you are connected from the moment you arrive, which is a key advantage for international travelers.
