The most efficient method is to procure a CoreESIM plan online well in advance of your journey. Following your purchase, a unique QR code will be sent to your email. Scanning this code with your compatible device will promptly download and install your eSIM profile. This proactive measure ensures that you can activate data immediately upon landing at JFK, LGA, or Buffalo Niagara International Airport (BUF), providing seamless connectivity from the moment you arrive in New York State.
