To use your phone and account to buy a plan for a different device:

• Open the app on your phone and select the plan that you wish to purchase for the other device.
• When you get to the Order Summary screen, find the heading Select Target Device and tap the button below. This should be showing the name of your default device. NOTE: If you continue without changing the target device, the plan will be added to the eSIM on your default device.
• Scroll down the list and select the correct device. If you're buying for a new device, scroll to the bottom of the list and tap New eSIM Device.
• You'll be returned to the Order Summary screen. Check that the Target Device button shows the name of the correct device (or "New eSIM Device", if you're buying for a new device).
• Complete the purchase by tapping Buy Plan.
• If you're buying for a new device:
  • You'll be prompted to Install Now. If you do not want to install the eSIM on the device you're using, or you want to install it later, tap Cancel. Otherwise, tap Install Now.
  • You'll be taken to the app's My Plans screen and your new plan will be at the top of the screen, labeled "Your eSIM has not been installed".
  • To change the name of the device, tap View Details.
  • A new screen will pop up from the bottom. Tap Unassigned.
  • You'll then see a list of devices. Locate the entry for "Unassigned" and tap Rename.
  • Enter a new name and tap Save.
  • The device will be renamed.
• When you want to install your eSIM, tap Install eSIM.
  • To install on the device you're using, tap Install on this device.
  • To install on a different device, tap on the type of device, tap Install Now, and follow the instructions.
