The CoreESIM installation process for San Francisco is designed for pre-travel completion. Following your CoreESIM data plan purchase, a QR code will be dispatched to your registered email. Utilize your compatible device's camera to scan this QR code directly from the email, or input the SM-DP+ address and activation code manually within your cellular settings. Ensure the eSIM profile is installed and designated as the primary data line before your departure, enabling immediate network registration upon landing in the United States.
