If you have an iPhone that supports dual-SIM support, you may have noticed the Last Line No Longer Available error message popping up whenever you try to make a call from your contact or recent calls list.
This issue isn’t exclusively an iPhone 14 problem, but also affects other dual-SIM iPhone models like the iPhone 13, 12 and older models running iOS 16. Thankfully, there are several ways to fix the “last line no longer available” error on your iPhone.
What is the last line?
The last line is a fancy name for the last phone call you make on your iPhone. It’s also the name of a new feature in iOS that allows you to switch between multiple SIMs so you can save money and not have to swap out your SIM card every time you call a friend or family member. The best part is that you can get this functionality for free.
In fact, it’s so cool that Apple has even made a dedicated app for the task called last line. It’s a small but mighty piece of software that can improve your phone’s overall connectivity by removing lag and other network bottlenecks. It also lets you make and take calls without having to unlock your phone. If you don’t like the idea of giving your phone a little bit of personal information to make a call, you can turn this off via the settings for your preferred carrier.
What causes the last line to be unavailable?
When you try to make a call on your iPhone, you might receive a message saying “last line no longer available.” This is an error that is commonly seen on dual-SIM supported iPhones. It is most likely caused by a bug in the cellular radio of your phone.
A common solution that works for many users is to clear their Recents call list in the Phone app. This should fix the last line no longer available issue for most iPhone users. To do this, open the Phone app and tap on the Recents tab at the bottom of the screen.
Another fix that works for some iPhone users is to reset their network settings. This will wipe out all information related to their mobile plan, VPN and Wi-Fi credentials. If this doesn’t work, you can also try restarting your device.
Lastly, updating your iOS to the latest version might fix the last line no longer available issue on your iPhone. To do this, open the Settings app on your device and go to General > Software Update.
Sometimes, the last line no longer available error on your iPhone is due to a bug in the iOS software itself. To fix this, Apple releases updates to its software on a regular basis.
One of the first things to check for a problem like this is to see if an iOS update has fixed it. If an update is available, install it to see if it fixes the last line no longer available issue for you.
This is probably the most effective way to fix the last line no longer available issue on an iPhone. If this doesn’t work, you may need to contact Apple Support to get the problem resolved.
If the last line no longer available error on your device persists, you might need to try removing and reinserting your SIM card. This is a fairly old trick that has been known to solve many network-related issues on iPhones.
If none of these methods solve the last line no longer available issue for you, you might need to contact your network provider to see if they have any updates that can fix the problem. Fortunately, most network providers update their carrier configurations on a regular basis to improve their connections and security.
How do I fix the last line to be unavailable?
If you have a dual SIM iPhone, you may experience the “Last Line No Longer Available” error occasionally. It is usually a network-related issue, but there are ways to fix it.
One solution is to reset your phone’s settings. This can help to clear the cellular data, which will prevent the Last Line No Longer Available error from appearing again.
Another way to fix this issue is to update your carrier settings. Most carriers release updates regularly to improve cellular network performance and get rid of random issues. You can check if an update is available for your carrier by opening the Settings app and navigating to General > About.
You can also try clearing your recent calls list. This can fix the Last Line No Longer Available issue if you have been making calls from multiple SIMs recently.
Disabling automatic network selection on your iPhone can also resolve this problem. This feature automatically connects to a nearby cellular network when you’re near a cell tower, which can cause this error. To disable this feature, open the Settings app, tap Mobile Data, and then turn off the Automatic toggle next to Network Selection.
If the problem still persists, you can try disabling Wi-Fi calling. This service allows you to make and receive calls over a connected Wi-Fi network in areas with poor cellular reception, but it can also conflict with your iPhone’s cellular settings, causing this error to appear.
Lastly, you can try removing and reinserting your SIM card to see if that helps. This will re-establish the connection with your carrier and fix the cellular data issue that is causing this error to appear.
If none of the above methods work, you can try updating your iOS device to the latest version of Apple’s operating system. This will allow you to fix the Last Line No Longer Available error and restore calling functionality. If the issue remains, you can always take your phone to an Apple store for more support.
How do I get the last line to be available?
The last line on an iPhone is a bit of a misnomer. It’s not an actual line, it’s a graphical representation of the current status of cellular connectivity on your device. While it’s a cool gimmick, it’s also a bit of a pain to use when you’re trying to make a call on your phone.
The “last line” problem occurs when you try to make a call using your default cellular line and your smartphone can’t make a connection. It’s usually not a big deal, but it can be annoying.
Fortunately, there are some ways to get around this issue. One of the most important is to understand what the problem is.
In most cases, the solution involves a bit of fiddling with settings on your device. It may require a reboot or some kind of software update, but there are ways to solve this oh-so-frustrating bug.
Aside from resetting the network, you can also try switching between your primary and secondary SIMs on your device. This may be a bit of a hassle, but it’s definitely worth the effort.
Finally, you can also try to clear your call logs and see if that fixes the last line on your iPhone. While it might sound like an odd suggestion, this has worked wonders for many iPhone owners.
You might also want to check out the latest iOS version available for your device and update it. There’s always a chance that Apple will fix the “last line on an iPhone” bug in a future update.
