Absolutely. CoreESIM strongly advises configuring your eSIM for Arizona before your arrival in the USA. This proactive approach ensures immediate data connectivity upon landing. After purchasing your plan, CoreESIM will provide a QR code or manual activation details. You can complete the eSIM profile installation on your compatible device while still connected to your home Wi-Fi network. Once installed, simply enable the eSIM line in your device settings upon arrival in Arizona to connect to partner networks like T-Mobile or AT&T, bypassing any airport-related connectivity delays.
