Part 1: Why is iPhone Saying Last Line No Longer Available?
iPhone users may occasionally encounter an error message saying that “Last Line No Longer Available” and wonder what the meaning is. Typically, this error usually occurs when the default SIM carrier does not support VoLTE (Voice over LTE), and because of this the iPhone automatically falls back to 3G or 2G (which does not support VoLTE) and is unable to connect to the network using the last line you used for making calls. As a result, you see the “Last Line No Longer Available” error, followed by “Do you want to call using your remaining line?” prompt.
If you are using an iPhone with dual-SIM or eSIM functionality, you may not be able to place a call using the most recent call history (default or primary SIM). Instead, you will be prompted to use the remaining line (the secondary SIM). This is what the "Last Line No Longer Available" error means.
Part 2: 10 Quick Fixes to the Last Line No Longer Available Error
After learning why the "Last Line No Longer Available" error appears, you may want to know how to fix it to make calls on your iPhone normally. Following are some quick fixes you can try to fix the "Last Line No Longer Available" error.
1. Check Internet Connection
Ensure that your iPhone is connected to the internet either via Wi-Fi or cellular data. You can check this by opening a web page or using a different app that requires internet access.
2. Turn Airplane Mode On and Off
You can try to toggle on and off the Airplane mode on your iPhone to fix the “Last Line No Loner Available” error. Just swipe down from the top right corner of your iPhone screen to open the Control Center, then tap on Airplane Mode button, wait for seconds, tap on the button again to turn it off.
3. Restart iPhone
Sometimes restarting your iPhone can resolve any temporary software glitches. You can try this method when you cannot find why your phone says Last Line No Longer Available.
4. Clear Recent Call History
If you receive the “Last Line No Longer Available” error when you dial a contact or number on your “Recents” list, delete the call log associated with the number and try again. If you find the error occurs on all the numbers in your iPhone's “Recents” list, clear the entire call history then.5. Disable Wi-Fi Calling
Another quick fix to try is disabling Wi-Fi calling. Wi-Fi calling enables you to make and receive calls via Wi-Fi in areas that have poor cellular signal strength, but it may cause conflicts and result in the “Last Line No Longer Available” error on your iPhone.
To disable Wi-Fi calling, go to your Settings app, tap on Cellular/Mobile Data, and then on Wi-Fi Calling. Now turn off the switch next to Wi-Fi Calling on This iPhone.
6. Update to the Latest iOS Version
Ensure that your iPhone is running the latest version of iOS. If there is an available update, download and install it.
7. Reset Network Settings
Resetting your network settings can resolve any issues related to your iPhone's internet connection. Go to the Settings app and tap Reset Network Settings from Reset. Note that this will erase your Wi-Fi passwords and VPN settings.
8. Disable Automatic Network Selection
Open the Settings app, navigate to Cellular > Network Selection, then turn Automatic off.
9. Reinsert SIM Card
If you are using a physical SIM card as your default line, you can remove it and then insert it back to fix the “Last Line No Longer Available” error.
10. Check Phone Line Status
Contact your service provider to confirm that your phone line is active and in good standing. If your line has been disconnected, you may need to reactivate or subscribe to a new service plan. And you should check the cellular data on your eSIM card. Otherwise, you may not be able to make a call.
