Do I need to install a new eSIM every month?

No. Once your Global eSIM plan is installed, you don't need to install it again.

Your subscription auto-renews on its own, so your data refreshes automatically with no extra setup or reinstallation. How often it renews depends on your plan: a monthly plan renews every month, and a yearly plan renews once a year.

Any unused data rolls over to your next renewal, so you never lose what you've already paid for.
