What Does the “Last Line No Longer Available” Error on iPhone Mean?

Most of us have been there before- you’re trying to send a text message, but instead of the usual “send” button, you see a dreaded “last line no longer available” error.

When this happens, it usually means that your iPhone’s message app is having trouble sending or receiving texts.

There are a few things you can try to fix the problem, but if all else fails, you may need to contact your carrier for help. In the meantime, here’s a quick guide to help you troubleshoot the issue.

1. Switch Phone Lines Manually on iPhone

Your iPhone is a sophisticated piece of technology, and one of its most impressive features is its ability to switch phone lines automatically.

However, there may be times when you need to switch lines manually. For example, if you’re on a call and your battery starts to die, you may want to switch to a different line so you can continue the call.

Or if you’re in an area with poor reception, you may need to switch to a different line in order to make or receive calls. Luckily, switching phone lines on your iPhone is easy. Here’s how to do it:

Open the Phone app and tap the Keypad tab. Enter *#31# followed by the number of the line you want to switch to. For example, if you want to switch to Line 2, you would enter *#31#2. Tap Call.

Your iPhone will now switch to the specified line.

2. Toggle Airplane Mode On and Off on iPhone

Airplane Mode

Regardless of whether you’re trying to save battery life or just want to be left alone, airplane mode is your best bet. But what exactly is airplane mode?

When you toggle airplane mode on, your phone will cut off all communication with the outside world. That means no more text messages, emails, phone calls, or even access to the internet. In other words, it’s like your phone takes a little vacation.

Of course, that also means you can’t use any of your phone’s features that require an internet connection. So if you’re planning on playing games or watching videos on your flight, you’ll need to make sure you download them before turning on airplane mode.

But for everything else, airplane mode is a great way to disconnect from the world and enjoy some peace and quiet.

3. Restart Your iPhone

Hardly any device is more dependable than an iPhone, but when it comes to fixing errors like “Last Line No Longer,” you’ll want a simple solution. Simply turn off your phone and boot it back up in order to restore the function once again! Here’s how to do it:

Press and hold the Sleep/Wake button on the top of your iPhone until the “Slide to power off” slider appears. Swipe the slider to turn off your iPhone. Once your iPhone is turned off, press and hold the Sleep/Wake button again until you see the Apple logo.

And that’s it! Once your iPhone has restarted, hopefully, the problem will be gone. If not, you can try restarting your iPhone again or contacting Apple for further support.

4. Clear Your iPhone’s Call History

  1. Open the Phone app and switch to the Recents tab.
  2. Tap Edit.
  3. Tap the Delete icon next to each entry related to the contact or number.

Delete the entire call log if the error occurs for every number on your iPhone’s “Recents” list. To do that:

  1. Open the Phone app, switch to the Recents tab, and tap Edit.
  2. Tap Clear.
  3. Tap Clear All Recents.

If you’re like most people, your iPhone’s call history is a never-ending list of missed calls, wrong numbers, and embarrassing exes.

Luckily, it’s easy to clear your call history and start fresh. Just open the Phone app, tap on the Recents tab, and select “Clear” at the bottom of the screen.

You can also choose to delete individual calls by swiping left on a number and tapping the trash can icon. And if you’re worried about someone snooping through your call history, you can always enable the “Last Line No Longer Available” setting.

This will ensure that anyone who tries to view your call history will only see a blank screen. So go ahead and clear your call history – it’s as easy as that!

5. Update the Carrier Settings on iPhone

It’s always a good idea to keep your iPhone’s carrier settings up to date. Not only will this help to improve your signal strength and call quality, but it can also fix any network-related bugs that may be causing problems.

To check for carrier settings updates, simply go to Settings > General > About. If an update is available, you’ll see a prompt to install it.

Just follow the instructions on the screen, and you’ll be all set. So next time you get the “Last Line No Longer Available”, make sure to give your carrier settings a quick update. It might just save you a lot of headaches in the long run.

6. Avoid Using Your Preferred Line for Cellular Data

  1. Open the Settings app and tap Cellular.
  2. Tap Cellular Data.
  3. Select the other phone line or Off to disable cellular data altogether.

If you’re anything like me, you have a preferred line for your cellular data. Maybe it’s the line with the best reception or the one with the most data.

Whatever the reason, it’s important to avoid using your preferred line for cellular data as much as possible.

Here’s why: your preferred line is probably the one that gets the most use. And the more use it gets, the more likely it is to drop calls, or worse, lose data entirely.

So if you want to keep your cellular data service reliable, it’s best to spread the love around and use all of your lines equally.

That way, if one line goes out, you’ve got a backup. And isn’t that what we all need in life? A backup plan. So do yourself a favour and avoid using your preferred line for cellular data.

Trust me, you’ll thank me later.

7. Disable Automatic Network Selection on iPhone

As any iPhone user knows, there is nothing more frustrating than having your phone lose its signal when you need it the most.

Whether you’re trying to make an important call or access the internet, a dropped connection can be very frustrating. One of the most common causes of this problem is Automatic Network Selection, a feature that automatically switches your phone to the strongest available signal.

Unfortunately, this feature can also cause your phone to lose its connection in areas with poor reception. If you’re tired of having your phone drop its signal, you can disable Automatic Network Selection by following these simple steps:

  1. Open the Settings app on your iPhone.
  2. Select the “Cellular” menu option.
  3. Scroll down and locate the “Automatic Network Selection” setting.
  4. Toggle the setting to “Off.”

By disabling Automatic Network Selection, you can help prevent your iPhone from losing its signal in areas with poor reception. However, you may also find that your phone has trouble connecting to certain networks, so be sure to test this setting before relying on it in an emergency situation.

8. Disable Wi-Fi Calling on iPhone

While Wi-Fi calling is a great feature, there are times when you might want to disable it. For example, if you’re in an area with a weak Wi-Fi signal, you might want to disable Wi-Fi calling to avoid dropped calls.

Or, if you’re trying to conserve battery life, you can disable Wi-Fi calling and rely on your cellular connection instead. Thankfully, disabling Wi-Fi calling on your iPhone is a quick and easy process. Just follow these simple steps:

  1. Open the Settings app on your iPhone.
  2. Tap Cellular.
  3. Tap the switch next to Wi-Fi Calling.

And that’s all there is to it! Once you’ve disabled Wi-Fi calling, your iPhone will automatically use your cellular connection when making and receiving calls.

9. Install the Latest Software Updates

iPhone users, it’s time to update your software. The latest iPhone software update includes a fix for a critical security vulnerability that could allow attackers to take control of your phone.

This is a serious issue, and you should update your phone as soon as possible. iPhone users who don’t update their software are at risk of having their phones hacked, and their personal data stolen.

So if you value your security, make sure to install the latest iPhone software update. And if you’re worried about the Last Line No Longer Available message, don’t worry, it’s just a warning that you need to update your software.

So don’t delay, update your iPhone today.

10. Reset Network Settings on iPhone

Network settings on the iPhone are pretty straightforward. You have the option to turn cellular data on or off, and you can select which apps are allowed to use cellular data.

But what happens when your network settings get all screwy? That’s where the “Reset Network Settings” option comes in. This will reset all your network settings back to their factory defaults.

That means any Wi-Fi networks you’ve previously connected to will be forgotten, and you’ll have to enter their passwords again.

It also means that any custom DNS settings will be erased. So if you’ve been having trouble connecting to the internet, or if your apps have been acting up, try resetting your network settings. Just don’t forget to enter your Wi-Fi passwords again afterwards!
