What Causes ‘Last Line No Longer Available’ Issue to Occur on iPhone?

For those who are unaware, iOS allows you to configure your default line (phone number) for iMessage and FaceTime when you have two SIMs active on your smartphone. Furthermore, the iPhone lets you use the default line when contacting or texting someone who isn’t in your Contacts app. You can set your default line for calls and texts and use the other line for cellular data alone, depending on your needs.
The issue prevents customers from dialling a number using their preferred SIM card. As a result, they are compelled to use the remaining line for that reason. So, we’ll show you how to cure the ‘Last Line Not Available’ mistake on your newly purchased iPhone 13.
How to Fix “Last Line No Longer Available” on iPhone?
We were unable to reproduce the issue because your iPhone does not support more than one SIM card. This makes testing potential fixes difficult.
That said, there are a variety of potential remedies available, the majority of which are anecdotal, with stories of “this worked for me” connected. So your mileage may vary, but if you get this mistake frequently, you’ll most likely have lots of opportunities to test out these options.
The first is self-explanatory: make sure you’re running the most recent version of iOS. Errors like this are frequently associated with defects, therefore updating your iPhone via Settings > General > Software Update will eliminate a potentially major variable. You can also attempt to update your available carrier settings by going to Settings > General > About and selecting “Update” when prompted.
Another common and simple solution is to enable Airplane mode in Control Center and restart your iPhone. Both of these will cause your network connection to be reset, which may remedy the problem. You can also try switching between SIM cards before dialling under Settings > Mobile/Cellular Data by pressing “Turn On This Line” next to the plan you want to use.
A comparable solution is to remove and replace your SIM card. On an iPhone, you can do this with a SIM tool or any thin sharp instrument, such as a paperclip.
Some customers noted that enabling (or disabling, then re-enabling) Wi-Fi calling resolved the problem. To do so, navigate to Settings > Mobile/Cellular Data and toggle the Wi-Fi Calling setting. Others have reported success after cleaning their recent call log under Phone > Recents by tapping Edit, Clear, then “Clear All Recents” in the pop-up that displays.
Finally, if you’re still having trouble, you may reset your iPhone’s network settings by going to Settings > General > Transfer or Reset iPhone and tapping “Reset” followed by “Reset Network Settings.” All cellular settings, VPN and APN settings, and Wi-Fi passwords will be reset to factory defaults.
