iPhone 13 'Last Line No Longer Available' Issue

Several iPhone 13 users have updated their device to iOS 15, but it seems that the said update may have included a bug.

The said bug pops up a message "Last Line No Longer Available: Do you want to call using your remaining line?"

To further explain the issue, the device tries to access the iPhone eSIM or known as electronic Subscriber Identity Module, instead of a physical SIM card, per Rocket Yard.

In the worst-case situation, the iPhone owners will be unable to make an outbound call. Moreover, the issue greatly affects several Apple devices that run an iOS 15 on it including the latest iPhone 13.

Luckily, there are ways to fix the iPhone 13 "Last Line No Longer Available" issue.

4. Delete Everything in the Call Log

Since it is linked with phone calls, Rocket Yard stated that this method has worked effectively.

2. Once the Phone app was located, head to the "Recents" button located on the bottom part of the screen beside the "Favorites" option.
3. After tapping the Recents button, choose the "Clear" button placed on the upper left corner of the screen.
4. Right after choosing the Clear button, tap the message pop-up "Clear All Recipients" placed in the bottom part of the screen.

Through this, it indicates that all numbers in the call log will be deleted.

However, if there is anything essential in the call log that iPhone 13 users wish to save, such as phone numbers or the date and time a call came in, Apple owners should take a screenshot of it.
