You can purchase an e-SIM as far in advance as you would like to. Follow these steps:

• Select the e-SIM you want to purchase.
• Complete your purchase.
• Your e-SIM will be added to your inventory. You can find them by going into Purchase History.
• Once you purchase your e-SIM, as long as it isn’t installed, you can wait to install it until you are on your trip.
