Why does this happen?
The ‘Last Line No Longer Available’ message is nothing new, as it has been observed on Apple iPhones since iOS 12. Dual-SIM iPhone models were affected by the problem. When a user uses the phone app’s recent logs to make a call from the default line, an error message appears on the screen that reads, “Last Line No Longer Available.” “Would you like to make a call on your spare line?”
When two SIM cards are active on the device, iOS allows users to set the default line (phone number) for iMessage and FaceTime. Furthermore, when calling or sending a message to someone who isn’t in the Contacts list, the iPhone allows users to use the default line. Users can configure the default line for calls & texts and use the other line for cellular data alone, depending on their needs.
Users are unable to dial a contact using their preferred SIM card due to the problem. As a result, they are compelled to use the last available line for that reason. So, we’ll teach you how to resolve the ‘Last Line No Longer Available’ error on several iPhone models.
