Before we jump into our expert tips, let’s first understand what exactly this “Last Line No Longer Available” error means.

This issue usually occurs when you attempt to initiate a call on your iPhone and the device falls back to 3G or 2G networks due to your carrier not supporting VoLTE (Voice over LTE). It’s been around since iOS 12 and can affect iPhone models that support dual-SIM functionality.

In a nutshell, this error might appear due to:

  • A bug or an issue with cellular radio
  • Corrupted call logs
  • Or improperly configured network settings

Enough talk; let’s dive straight into the problem-solving action!
