We recommend installing the RORO eSIM before your trip to avoid any delays. However, do not activate the data plan until you arrive at your destination.
Installing the eSIM ahead of time ensures that you are ready to use the data as soon as you reach your destination, but activating the plan before arrival may reduce the number of valid days. To maximize your plan's validity, complete the installation process and then activate the plan upon arrival.
Make sure you have a stable internet connection during the installation.
