How to Fix “Last Line no Longer Available” on iPhone?

One of the issues that you might face while using your iPhone is the “Last line is no longer available. Do you want to call using your remaining line?” error message. This happens when you are trying to dial a phone number and try to make a phone call. As it turns out, the error message is triggered when your phone is not able to choose a line. The error message is reported to be caused by the iOS update 12.1 in which case the eSIM goes active and as a result, the phone is having an issue on which line to choose even though you haven’t made any changes in the Settings.

As it turns out, the error message can be resolved quite easily. One of the ways that has been reported by other users facing the same issue that helped them fix it was simply clearing the old call logs. In addition to that, there are other workarounds as well that we are going to mention down below if clearing the call logs does not circumvent the error message for you. With that said, let us get started with the various methods that will help you resolve the issue so that you can make phone calls on your iPhone. So, without further ado, let us get into it.

Clear Call Logs

When you face the error message in question here, the first thing that you should do is clear your contacts from your recent call logs. As it turns out, this has been reported by several users who were facing the same issue and it resolved the error message for them. The reason this seems to be working is not really known and we couldn’t pinpoint why it tends to help during our research as well. Regardless, it does work and it might help circumvent the issue for you as well.

Therefore, go ahead and clear your recent call logs. To do this, follow the instructions given down below:

First of all, on your iPhone, open up the Phone app.
Once the Phone app is open, tap the Recents option at the bottom.

Switching to Recents Tab
On the Recents screen, tap the Edit option at the top-right corner.

Editing Recent Calls Log
Then, tap the Clear option at the top-left corner.

Clearing Recent Call Logs
On the dialog box that appears, tap the Clear All Recents option.

Clearing All Recent Call Logs
Once done, all the recent call logs will be removed. Go ahead and try to make a phone call to see if the error message still appears.

Toggle Network Selection

As it turns out, you have the option to set the phone to select a network automatically or you can alternatively select a network manually as well. In some cases, when the error message in question appears, it is due to the fact the phone is not able to select a network automatically which can happen when it bugs out. If this scenario is applicable, you will simply have to toggle the network selection setting located in the Settings app. That will restart the network selection service and you should be able to make a phone call without any issues. To toggle the network selection option, follow the instructions that are given down below:

First of all on your iPhone, open up the Settings app.
Then, on the Settings screen, tap the Mobile Data option. Depending on your iOS version, this can also be called Cellular in the settings.

Once you are in the Mobile Data settings, tap on the Network Selection option.

Tap on the Automatic to turn it off. Once you have done that, tap it again to turn on automatic network selection.

Network Selection
After that, go ahead and try making a phone call to see if you still encounter the error message.

Reset Network Settings

If the above solutions do not circumvent the issue for you and you are still unable to make phone calls, it is likely that the error message is being caused by your network settings. Resetting your network settings will remove all your network settings as well as removing any network profiles that you might have on your phone which includes forgetting any WiFi networks along with your bluetooth connections. Doing this will likely fix the error message in question here as it has for other users. To reset your network settings, follow the instructions given down below:

First of all, open up the Settings app on your iPhone.
Then, make your way to general settings by tapping the General option.

iPhone Settings
There, at the bottom, tap on the Reset option.

iPhone General Settings
On the Reset screen, tap on the Reset Network Settings option to reset your settings.

Resetting Network Settings
Once you have done, go ahead and try to make a phone call to see if the issue persists.
