Are you continuously getting the message “Last Line No Longer Available” whenever you try to make a call on your iPhone? Don’t worry. You are not the only one. Other iOS users experienced the same problem. In the following paragraphs, we’ll go over the meaning of the issue, why it appears on your iPhone, and the steps you can take to fix it. So, let’s begin.
What Does Last Line No Longer Available Mean?
The mistake on an iPhone with dual SIM capability seems to impact the favored line. You can experience the issue if you have more than one cellular plan connected to your iPhone utilizing both a regular SIM and an eSIM. The problem frequently happens when utilizing the recent call record found under Phone>Recent to dial out from the default SIM. An error message will appear, allowing you to call on your remaining line. You may press “Call” in the resulting window, but always be aware that it will make a call from any number that is not your default.
Causes Behind iPhone’s “Last Line No Longer Available” Problem
The “Last Line No Longer Available” problem has been on iPhone since iOS 12; therefore, it is nothing new. From iPhone XR to iPhone 13 Pro Max has all been impacted by the problem. The error message appears whenever a person attempts to contact the default line from the current logs of the phone app. Please make a call on the last line you have. If you have two SIM cards active on your smartphone, iOS allows you to change your default line (phone number), which iMessage and FaceTime use.
Additionally, the iPhone lets you call or text an individual not listed in your Contacts app using the default line. You can designate one line as your primary line for calls and messages while using the other line exclusively for cellular data based on your requirements. Users cannot dial a number via their chosen SIM card due to the problem. Therefore, they must use the final line to accomplish it. In the guide below, you may learn how to resolve the “Last Line No Longer Available” issue on your iPhone 13.
Which iPhone Models Get Affected?
This error reared its head with Apple’s first Dual-SIM iPhones in 2018, namely the iPhone XS and XS Max. Since then, any iPhone with dual-SIM capabilities has been susceptible to the issue. It includes all versions of iPhone 11, 12, 13, and 14 (including Pro and Max models). You won’t encounter this issue unless you use your iPhone’s dual SIM functionality. The first and second-generation iPhone SE does not have dual SIM capabilities, so you should not encounter the problem with that device.
