CoreESIM strongly advises installing and activating your eSIM prior to your arrival at Toronto (YYZ) or Vancouver (YVR). You can complete the installation process from your home country. The validity period of the eSIM will only commence once it registers on a Canadian network. This proactive approach ensures immediate data connectivity upon landing, bypassing potentially slow or insecure airport Wi-Fi, and allowing you to access essential services like ride-sharing apps or navigation without incurring expensive roaming charges.
