Update Your Device to the Latest iOS Version 

It often happens that we face some unexpected issues that we have never had before. Most of them could be because you are running your device on an outdated iOS version, Apple keeps on updating its operating system, and with each update comes a new bug-fixing technology. This is what makes it crucial to keep our iOS devices up to date

To check if there’s a pending update, visit the Settings section of your device>> General>> Software Update>> and there you will see if there’s an update available or not; if there is, click on it to download and install it on your device. Once done, check if your iPhone still says the last line is no longer available.

Toggle the Airplane Mode

Sometimes the simplest and the most unexpected solutions can be your way through issues. The same goes for this case when you are left wondering what “last line no longer” available means on iPhone. Plus, this is more like a network issue, so you may switch on and off the airplane mode on your device. 

Once you do that, your iPhone will detach itself from the cellular data that you have been using before attempting to reconnect. For this, simply either visit the Settings app or launch your control panel, turn on the Airplane mode first, and then switch it back off. Now check if the issue is resolved or not.

Remove and Insert the SIM Again 

Try removing or deleting your current SIM from the SIM tray and then reinserting it.

Now remove the tray from the slot, wipe it properly, insert the SIM back, and then the tray into the slot, and now check if it’s working properly or not. 

Disable Wifi Calling on Your Device

Most people might not know about this, but Wifi calling is a feature with the use of which users can make calls over the internet without having a network connectivity issue.

Update the Carrier Settings

You must be aware of the settings that connect your iPhone to a mobile network that allows calling and messaging. That network setting is carrier configuration. Although these settings are configured in each device once they are turned on by the user, the network providers can make some amendments to it after some updates to grant users better connectivity.
