Part 1. What Does Last Line No Longer Available On iPhone Mean?

In essence, the iPhone's "Last line no longer available" error occurs when your phone cannot choose a line to make a call. Some have speculated that it is because of the new iOS update. It seems to be messing up the eSIM support on the phone.

When trying to make a call, you will see a pop-up stating the error. Users are not left with much choice after that. You can either try to call again from your spare line or cancel the pop-up. There are a couple of possible reasons why this might occur.

But this feature launched with the iPhone XS. That was quite a while ago. However, the last line no longer available bug is recently in the conversation thanks to iOS 15.

The combination of one line being an eSIM and the other line being a physical SIM card seems to be confusing for some phones. And the software gets freaked out giving out the error.

Sometimes users can be replicated as well if they have WIFI calling or network selection on. Users encountered this problem the most when attempting to call from the recent call logs.

1Restart Your iPhone

Restarting your phone is the most basic troubleshooting step. Sometimes software breaking bugs are pretty hard to replicate. So, restarting the device will usually fix it. It clears the RAM cache. That means it will give your phone a clean slate to run off of. Restarting an iPhone is pretty easy.

Other iPhones

2Turn On Airplane Mode

Another option is turning on airplane mode. When it comes to any issues with calling on your phone, it is a network-related issue. To fix these issues, airplane mode can come to the rescue. Airplane mode detaches from your current network. And then when you turn it off, your phone will connect to the nearest network tower. Here is how to do it:

Go to Settings. Toggle Airplane Mode on. It should be the first setting you will see after your iCloud name.

Wait a couple of seconds and then turn it off. It will connect to your SIM network and you can make calls again.

3Turn Off Network Selection

Smartphones are smart enough to automatically connect to the strongest network. They do this by checking what networks are available around them. Then they will pick the best one. But this convenience can sometimes not work as expected. Turning off network selection and connecting manually can do the trick though.

Go to Settings. Click on Cellular.

Turn off Automatic Network Selection. Now, select the network you would like to be on.

4Re-enable Wi-Fi Calling

In some cases, WIFI calling is causing issues with the iPhone 13 last line no longer available error. So, turning it off and then re-enabling it can help. Here is how:

Go to Settings. Tap on the Mobile Data sub menu.

Tap on WIFI calling. Turn the toggle off.

Follow the same steps above and then enable it. However, this troubleshooting method seems to be a bit of a wildcard. It fixed the issue for some; others did not have much luck.

5Switch Between SIMs

Since the issue is the SIM card. You can also try switching between your SIM cards. iOS has a feature to let you pick which SIM you want to use. Change the default line or calling and texting.

Go to your Recent call logs. Tap on the i button next to the contact.

Choose an alternate number instead of the default.

When call a phone number, choose the alternate SIM.

6Reinstall SIM Card

Just like turning your phone off and on, you can also try reinstalling the SIM card. This one is quite simple. Turn your iPhone off. Use a SIM ejector tray to remove the card. Wait for 5 to 10 seconds and then install the SIM card back into your phone

7Reset Network Settings

Another trick you can try is resetting your Network settings. It will reset all connections and tell your phone to start from scratch. This little trick might solve any network-related issues you might be facing. The process for this is pretty simple.

Go to the Settings app. Tap on Transfer or Reset iPhone.

Tap on Reset. Select Reset Network Settings.

8Clear Recent Call Log

As we mentioned before, users are facing this issue when they are calling contacts from the recent list. Clearing the recent call log sometimes fixes the issue. However, this is not a sure shot though. But it is worth a try. Here is how to do it:

Tap on the Phone app. From the bottom menu, go to Recent.

On the upper right-hand corner, you will see an Edit option. Tap it.

Now a Clear option will appear in the upper left-hand corner. Tap it to clear the list.

9Check Software Update and Carrier Settings

The software has come a long way. However, some bugs creep their way into development. The good thing about Apple is that they are pretty good with their updates. So, if you are facing any kind of software issues, updating can be a solid fix. In this case, you have to check for both carrier setting and software updates.

For carrier settings update: Go to Settings > General > About, tap on Update.
