How to install and activate an eSIM on an iPhone?

We recommend installing your eSIM no sooner than the day before of the day of your journey.
If you activate your eSIM beforehand, you will lose days of usage. Remember that a Holafly eSIM can be activated automatically by connecting to the mobile network. In other words, you don't need to connect to the internet to activate it.
If you're already at your destination, you can do it right away.
