How to Fix “Last Line no Longer Available” on iPhone?

Last month, Apple unveiled iOS 15 and the iPhone 13 devices around the same time. Customers have been rather outspoken about what the company offers, with some full appreciation and others harsh criticism. The ‘Last Line No Longer Available’ message from time to time inside the Phone app is one of the issues customers are experiencing.

Worse, the problem isn’t restricted to the newer iPhone 13 devices; it also affects the iPhone 12 and 11 series.

What Causes Last Line No Longer Available on your iPhones?

The Last Line no longer Available is an error that usually pops up when any user is about to make a call on their iPhone 13 significantly after you have activated your Phone for the first time. This issue appears because of the bug linked with the e-SIM function on some of the newer iPhones. 

Now e-SIMs are digital SIMs that enable the use of dual-SIM in the iPhone modes that are above iPhone XS/Max, in iPhone XR, iPhone 11 series, iPhone 12 series, and iPhone 13 series. Those users have been facing the ‘Last Line No Longer Available’ error that appears as soon as they are about to make a call using the default line Phone application’s recent call logs. The default line is the SIM you use to call and message people. 

This issue prevents users from making the call through the SIM card you prefer for your dialing. This results in users using alternative means of communication. This problem also occurs in older phones, especially after the recent iOS upgrade.

  • A later model iPhone (XS, XS Max, or XR) with iOS 12.1 or later.

When you have finished activating your eSIM, go ahead and give each of the cellular plans a unique name. These labels will assist you in identifying the numbers so that you can choose which ones to utilize for data, calls, and messages. When it comes to designating a number for each of your contacts, naming the profiles might also be helpful. In addition to that, you should decide on a default number to call those who do not appear on your contact list.
