What Causes the ‘last line no longer available’ Error?

After this issue came to light, we started nitpicking some user guides and common repair strategies, while compiling this guide, we also thought that it is vital for you to know why this error occurs in the first place. For that purpose, we have compiled the following list.

  • Recent/ Missed Contacts: It has been seen from users’ testimony that after Apple introduced the e-sim functionality or updated it in their recent iOS update, users were unable to call any numbers on their phone. This was caused because the phone had been glitched due to the record of the previous call logs. This glitch can easily be rectified simply by clearing those call logs and for most users that turned out to be the issue.
  • Network Settings Glitch: Another common trigger behind this problem was the incorrect configuration of the Network settings on the users’ iPhone. Due to this, the user was unable to make any calls to any other person because the network settings were causing the ‘Last Line no Longer Available’ Error every time they tried.
  • Network Selection Setting: In some cases, the network selection setting on the iPhone might have been configured incorrectly or it might not be properly set due to which the ‘Last Line no Longer Available’ Error is seen while trying to select a particular network.
  • Sim-Card Glitch: In some rare cases, it was seen that the SIM card was not properly inserted inside the SIM tray due to which this particular issue was being triggered while trying to make a call. Therefore, if you are continuously getting the ‘Last Line no Longer Available’ message on your device and are unable to pinpoint the issue, you could always try to reset the SIM card in the SIM tray.
