Line No Longer Available After Switch to eSIM

As part of the upgrade process to my new iPhone 13 Pro Max, I decided to switch from using a physical SIM card from my wireless carrier to a new fangled digital SIM, known as an eSIM.

However, after switching from the nano-SIM in my iPhone 12 to an eSIM with my iPhone 13, I started receiving a Last Line No Longer Available warning, as the following screen capture shows.

It turns out that this is a problem that has been around since iOS 12.1 when the eSIM feature was first introduced with the iPhone XS, iPhone XS Max, and iPhone XR.

To ‘fix’ the issue, all I needed to do was to go into the Phone app and clear the list of recent calls.

1: Tap the green Phone.app icon.
2: Tap the All tab at the top of the screen.
3: Tap the blue Edit button in the upper right of the screen.
4: Tap the blue Clear button in the upper left of the screen.
5: Tap the red Clear All Recents button at the bottom of the screen.

Now, test calling a number that previously gave the warning message and it should be gone.
