What is Last Line No Longer Available error?

iphone error 1

In case you didn’t know, if you have a dual-SIM iPhone, Apple mandates that you designate one SIM as the main line/default connection for all outbound calls, even FaceTime calls. Simply said, a primary line is the number you desire to employ for all outward messages and calls on the iPhone.

When you set a primary line, your iPhone will automatically dial that number whenever you place a call, saving you time that would otherwise be spent selecting a contact’s number. When using a dual-SIM iPhone, choosing a primary phone number can cause the dialer app to become confused, resulting in a pop-up window reading “Last Line No Longer Available.

The notification indicates that your primary phone line isn’t active at the moment, and that you should switch to using your iPhone’s secondary line (or SIM card) to make calls. Selecting the Call button in this popup will cause your iPhone to make a call utilizing the secondary line.

To access the settings menu, swipe down from the upper right corner. Use the airplane button to activate the feature. Just give it a minute or two to cool down before you shut it off.

3. Wipe Out Recent Call History

Even if erasing your recent call logs may be something you’re not happy about, it’s a simple solution to the problem. It’s also possible that you’ll continue to see this issue every time you try to make a call from your recent calls list; until then, you’ll have to work around the mistake. Let’s see how you can go on erasing the call log:

  • Open Phone Apps
  • Head to the Recent option
  • Hit on Edit
  • Select Clear, and to confirm, Clear All Recents
  • Turn Off Automatic Network Selection

It’s possible that the “Last Line No Longer Available” message on your iPhone is the result of Automatic Network Selection (ANS). This function, that compels the iPhone to choose what network to link to, does not work properly on dual-SIM iPhones.

If you don’t want your iPhone to automatically dial numbers, you should disable this option. To turn off ANS, click Settings, then go to Cellular, and finally pick Network Selection. Then, flip the switch that is next to Automatic so that it is not on. Choose the network you want to use after turning off ANS.

4. Perform a Reset of Your Network Settings

It could be a software issue if your iPhone suddenly stops allowing you to access a certain line. Therefore, resetting the settings will be sufficient to deal with issue.

To do a factory reset, navigate to the “General” section of your phone’s settings. To do so, select “Reset” and then “Reset Settings” from this menu. It also doesn’t wipe your phone’s data, so you don’t have to worry about making backups.

Simply remove the SIM card, take a few seconds, and then re-insert it into the phone. Finally, switch on the iphone by pressing and holding the power switch. Next, try making a call from your iPhone’s default line to check if the problem still occurs.

5. Disable WiFi Calling

iPhones with the Wi-Fi calling function can leverage an existing wireless connection to place and receive calls. In this approach, your iPhone call will go through the Wi-Fi network rather than the cellular one. Using a Wi-Fi connection for phone conversations, however, might occasionally cause problems like the “Last Line No Longer Available” message. If you’re experiencing this problem, turning off Wi-Fi calling might help.

6. Update Carrier Settings

The iPhone must be set up with the appropriate carrier settings in order to establish a connection to a mobile network and exchange data with it. Despite the fact that the iPhone’s carrier settings are activated immediately upon first activation, network operators could alter much of its systems to enhance the stability and security of the connection at a point later.

There may be a glitch in the iPhone’s carrier configuration if the “Last Line No Longer Available” problem emerges. It’s great that carrier settings upgrades are sometimes available, just like iOS updates. The iPhone carrier settings can be updated in the Settings app by selecting General > About.

7. Reset All Settings

If the “Last Line No Longer Available” problem persists after attempting the aforementioned solutions, you can try erasing all of your iOS settings without erasing your data. Given the gravity of the situation, having to reset your iPhone to factory settings ought to be the least of your concerns. Let’s check the steps to achieve the same:

  • Head to the Settings column
  • Select General
  • Choose Transfer or Reset iPhone
  • Finally, hit on Reset
  • From the varied list of choices, Reset All Settings

Following that procedure, your iPhone will restart and load as “nearly new,” with all of your custom settings deleted but all of your images and other data preserved. See if your iPhone is working properly for making calls.
