Why the “Last Line No Longer Available” Error Occurs

The “Last Line No Longer Available” issue is a common annoyance for iPhone users, especially those who use dual-SIM or eSIM capabilities. So, what causes this vexing message? When your default SIM carrier doesn’t offer VoLTE (Voice over LTE), the issue arises. Your iPhone switches to a lower-grade network like 3G or 2G and cannot make calls from the recent call record. As a result, you receive the “Last Line No Longer Available” error and are advised to use your secondary SIM card for calling.

Another underlying cause could be network problems or faults in the iPhone’s operating system. Errors in network setup settings, such as automated network selection, might potentially contribute to the “Last Line No Longer Available” issue. Call log corruption or bad mobile signals may be at fault. Although the situation may seem difficult, it may often be solved without Apple’s help. Understanding the root reasons may help you fix and prevent the issue. For more related fixes, you might find our guide on 5 Proven Steps to Fix SOS Only Error on Your iPhone helpful.

Stumbling upon the “Last Line No Longer Available” error on your iPhone can be a real headache, especially when you’re in urgent need of making a call. Fortunately, you don’t have to throw your hands up in frustration. Several methods can quickly help you resolve this issue. Here’s a more detailed look at some key solutions:

1. Utilizing Airplane Mode to Refresh Network Settings

5. Deactivating Auto-Select for Network Providers

Encountering the “Last Line No Longer Available” error may be frustrating, but one effective workaround involves manually controlling your network selection.

What It Accomplishes: By disabling the automatic network selection, you’re essentially taking charge of which carrier your iPhone connects to, possibly averting the “Last Line No Longer Available” issue.
