Several iPhone users who encountered the "Last Line Not Available" issue stated that erasing the recent call history solved their problems. While it may sound strange, we have experienced several unusual methods that have helped us solve challenges in the past. So don't pass this one up, either.

Way 5: Update Carrier Settings

Another option for troubleshooting the "last line no longer available on a single SIM" issue on your iOS device is to change the carrier settings. The problem could be due to a carrier network, which you can remedy by upgrading the carrier configuration on your device. The good news is that carriers frequently deploy upgrades to improve general network performance and eliminate sporadic glitches.

• Navigate to General -> About in the Settings app on your iPhone. You may now receive a notification prompting you to change the carrier settings.

• Then, on the pop-up window, click "Update", and you're done!

  

Way 6: Disable WiFi Calling

WiFi calling is a handy function, particularly for persons who frequently find themselves in regions with poor cellphone signals but excellent WiFi reception. However, WiFi calling might occasionally result in issues such as the last line no longer available error message. Disabling WiFi calling can resolve the issue.

• Navigate to Settings > Phone > WiFi Calling.
• To disable the feature on your iPhone, turn off the toggle next to WiFi Calling.

Way 7: Disable Automatic Network Selection

Automatic Network Selection is another cause of the "last line no longer available do you want to call using your remaining line" iPhone issue. It prompts your iPhone to select the best network to connect to but presents problems for Dual-SIM iPhones.

• 1. To turn off Automatic Network Selection, go to Settings > Cellular > Network Selection.

• 2. Then, deactivate the option next to Automatic Network Selection and select a carrier network.

  

Way 8: Remove & Reinsert SIM

Have none of the previous ideas worked to solve your problem? So, please take out the SIM card and replace it. This age-old method has helped many people get rid of cellular troubles. Turn off your iPhone and remove the SIM tray using a SIM ejector tool. Wait a few seconds before reinserting the actual SIM card.

Then, press and hold the power button to turn on your device. Next, place a call on your iPhone's default line and see whether you still get the "Last Line No Longer Available" problem prompt.

Way 9: Reset Network Settings

When you have a network problem, the one hack you always try is resetting the network settings to factory default. However, because the "Last Line No Longer Available" issue appears to be related to the e-SIM, we recommend you try this trick.

• 1. Go to the Settings app, General, Transfer or Reset iPhone, Reset, and then Reset Network Settings.

• 2. Enter your device's passcode again and pick the "Reset Network Settings" option in the pop-up to confirm your choice.

  

Way 10: Update iOS Version to iOS 16

Most iOS versions these days contain a slew of issues. While some are corrected in later versions, others persist for an extended period of time, particularly the less reported ones. Though it may appear to be a criticism of Apple's mobile operating system, it is an unpleasant reality.

A bug is most likely to blame if you are still experiencing the error when calling from the default line. As a result, updating the software could cure the problem. Download and install the latest version of iOS by going to the Settings app on your iPhone -> General -> Software Update.

Way 11: Turn off Find Contacts

Some Apple Community members reported that turning off Find Contacts solved the problem. Go to Settings > Contacts > Siri and Search > Siri and Search > Disable Find Contacts in Other Apps.
