When you call your default phone number on your iPhone, you may see a pop-up message saying that the last line is no longer available. This can be a frustrating issue, but it’s not as complicated as you might think.
The last line no longer available error is a result of an issue with the e-SIM part on your iPhone. If this is the case, you should try updating your carrier settings or resetting network settings.
What Does It Mean?
Do you regularly get the ‘last line no longer available’ error message on your iPhone when making a call? This problem has become quite common among users recently.
It is a frustrating issue, which affects all iOS devices, including iPhone 12/13 series and some older iPhone models. Fortunately, it can be fixed easily.
One of the most popular reasons for this problem is that you have a dual-SIM enabled device and have set the primary line as your default phone number. The Phone app prompts you when it detects that your device is set to use a different SIM than what’s set as your primary phone number and forces you to select the line you wish to use for incoming and outgoing calls.
Another reason is that you have an eSIM on your iPhone. This is a digital SIM that supports dual-SIM functionality on newer Apple iPhones such as the iPhone XR, XS, and XS Max.
However, some iPhone users have reported that this error occurs only when they try to make a call using the default phone number in their Recents log. It’s thought that this is due to a bug in the iPhone software or the eSIM.
The most common solution for the ‘last line no longer available’ issue is to reset the Phone app to its original state, which may fix the problem. You can do this by going into the Settings app and tapping General.
Alternatively, you can try to restore your phone’s configuration file. This should solve the issue, although it can be tedious and require a lot of patience.
Some users have also reported that clearing the recent call log in the Phone app helped them resolve this issue. In order to do this, go into the Phone app and tap on Recents.
While this sounds a little weird, it has been proven to work in the past for many users. You can also try to restart your iPhone or limit cellular data to your secondary line in the Settings app.
Lastly, it’s also worth trying to update your phone to the latest version of iOS. This will help ensure that you are running the latest software on your iPhone and it’s more secure and stable than before.
What Causes It?
If you have a dual-SIM iPhone and are receiving the “last line no longer available” error message, it means there’s something wrong with your phone. It can be annoying, but there are ways to fix it.
One of the most common causes of this problem is a bug in the carrier settings on your iPhone. Network providers can update these settings at any time to make sure your device is connecting with the network properly.
Fortunately, it’s usually pretty easy to find out which updates are causing the issue, and installing them will probably solve it for good. To do this, launch the Settings app, then scroll down to General > Software Update.
Next, click on the button next to Install New Software. After a few seconds, restart your iPhone.
Another way to fix the problem is to remove your SIM card and reinsert it, which will clear any traces of the old SIM. This is a tried-and-true method that has worked for countless people, and it should work for you as well.
You may also want to try deleting your call logs and resetting the phone’s network settings. This can help your iPhone identify which phone line it should use for calls.
If that doesn’t work, you can also try turning on Airplane Mode and then switching it off again. This will reset your connection to the mobile network and might fix the last line no longer available error.
Lastly, you can also try using a different cellular plan or switching off your cellular data altogether. This will force your iPhone to use a different phone line for calls and might prevent the error from occurring again.
If none of these solutions work, then there could be a hardware issue with your iPhone. If so, then you should consider getting a replacement. You can do that online through Apple’s website or by visiting an authorized repair shop.
How Do I Fix It?
If you have an iPhone with an e-SIM, you might experience a “last line no longer available” error when trying to make a call. This can be frustrating, especially since it’s often related to cellular network issues.
If your phone is experiencing this issue, there are a few things that you can do to fix it. One of these solutions is to re-set your network settings.
Another solution is to turn off WiFi calling. This may solve the problem, depending on where you’re traveling.
You can also disable automatic network selection on your device by navigating to Settings > Cellular. This feature prompts your iPhone to choose the best network to connect to, which isn’t ideal for Dual-SIM users.
Finally, updating your carrier settings can be a quick fix for a lot of iPhone cellular connection problems. Carriers frequently release updates to improve network performance and resolve bug issues.
To update your carrier settings, navigate to Settings -> General -> About -> Update Carrier Settings. If there are any updates available, tap “Update” to install them.
Alternatively, you can try a force restart on your iPhone. This will flush out all temporary files that might be causing the error and reset your network connection.
As a last resort, you can update your iPhone to the latest iOS version. Apple usually releases bug fixes with their latest software updates, so it’s worth giving this a shot.
