How to Fix Last Line No Longer Available Error on iPhones

How frustrating that you have a brand new iPhone, but you’re having trouble making phone calls from it. But don’t worry. You can usually fix the last line no longer available issue relatively quickly. Most of the time, you just have to reset some settings. Learn how to perform these resets by reading on.

What Does Last Line No Longer Available Mean?

This problem affects the preferred line on an iPhone with dual-SIM capability. You can experience the issue if you have more than one cellular plan connected to your iPhone, with an eSIM and a regular SIM. Basically, it occurs when your iPhone has trouble identifying which phone line to use during a call.

The error occurs the most frequently when using the recent call record under Recent to dial out from the default SIM after you’ve called that number from your other sim. An error message will appear that may not allow you to call your line. To call from any number other than the one you have set as your default, touch Call on the box that displays.

You may also get the message if you have taken out the sim or there is no network coverage currently available for that sim card. It’s possible it will occur after you record an iPhone call with a dodgy app.
