For Activation Date, people musually choose the date they arrive, but you can also select the date you want the eSIM to be effective, such as the day before your arrival or any specific day after your arrival. We thus recommend you choose your arrival date at your destination as your activation date. Be reminded that the activation time is before 10:00 AM (PSD) of the chosen date. Therefore, if you arrive early in the morning in PSD time in the US, it is recommended to advance one day as your activation date prior to the day of your arrival.
