When you try to make calls from the phone number that is set as the default on your iPhone, you keep getting the message “last line no longer available.”
There is no reason to be concerned because you are not the only one dealing with this issue. Several iPhone users have also expressed their dissatisfaction with the iOS 15 message that states the iPhone last line is no longer available. Do you want to know what the root of this issue is and how to solve it? The answers to all of your questions are included in this post for your convenience. Continue reading to find out the answer!
What does it mean when it says “Last Line No Longer Available”?
Whenever the user of an iPhone with a dual-SIM configuration attempts to make a phone call, the device may diplay a message that reads “Last Line No Longer Available” if it is unable to correctly identify the user’s default or preferred line. Although it occurs most frequently on iPhone 13 models, it is possible for other iPhone models that support Dual SIM to experience this issue as well.
When you try to make a call from the “default” SIM using the recent call log (which can be found in the Phone app under the Recents menu option), the error appears to occur the vast majority of the time.
After the error has been detected, you will then be presented with a message that provides you with the opportunity to make a call using the “remaining” line. You have the option of tapping “Call” in the box that appears on the screen; however, it is important to keep in mind that this will cause a call to be placed from any number other than the one that is set as your default.
Because of this error, users are unable to call another person using the line of their choice. They have no other option but to use the previous line for that purpose as well. WikiGuide will provide you with some pointers on “how to fix last line no longer available” later on in this post. Fortunately, there are solutions to fix this issue, and WiKiGuide will share them with you.
Why does it say “Last Line No Longer Available” when I check my phone?
The error has affected iPhone models that support dual SIM cards, such as the iPhone XS, the iPhone XR, the iPhone XS Max, the iPhone 11, 11 Pro Max, the iPhone Pro, the iPhone 12, 12 Pro, 12 Pro Max, the iPhone 12 mini, and especially the iPhone 13 models (iPhone 13, 13 mini, 13 Pro, and 13 Pro Max).
The question is, why does the error “Last Line No Longer Available” occur? The reason for this could be a corrupt call log, a random glitch or bug with the cellular radio, a network setting that wasn’t set up correctly, or something else entirely.
You are free to continue to use your other number, but keep in mind that doing so is not always advisable.
