Why do I get the ‘Last Line No Longer Available’ Error on my iPhone 13?

The ‘Last Line No Longer Available’ Error seems to pop up when a user is about to make a call on their iPhone 13 upon activating it for the very first time. Based on previous instances, this issue appears to be a bug that’s somehow related to the e-SIM functionality on some newer iPhones. An e-SIM is a digital SIM that enables the dual-SIM option on the newer iPhone models like iPhone 13 series, iPhone 12 series, iPhone 11 series, iPhone XR, and iPhone XS/Max. 

Users who are facing the ‘Last Line No Longer Available’ Error report that they’re alerted about the error as soon as they’re about to make a call from their default line through the Phone app’s recent logs. The default line is the SIM you prefer to use to make calls and send messages to people you haven’t saved as contacts.

The issue prevents you from dialing the contact through your preferred SIM card, forcing you to try alternate methods of communication. It doesn’t just affect the latest iPhone 13 models but has been a recurring phenomenon on older iPhones after a recent iOS update. Users on Apple Communities and Reddit have reported similar issues with their iPhones dating back to when iOS 12 was released in 2018, meaning even older iPhones with dual-SIM support may encounter this error.

If you use the dual-SIM option on your iPhone, then you can try switching your SIM for calling purposes without changing other preferences. If you’ve previously set a default line for calls and messages, you can change it by tapping on the ‘i’ button on the contact you want to call, selecting your default phone number on the screen, and then tapping on your alternate number. If you’re manually dialing a phone number using the keypad, tap on your Primary phone number from the top of your screen and then select your alternate SIM.

You can also toggle ‘Airplane Mode’ on/off for your phone from the Control Center. Swipe down from the top right to open the Control Center and tap on the Plane icon at the top left corner to enable Airplane Mode and then tap on it again to disable it. 

Fix #4: Restart your iPhone

If you still continue to get the ‘Last Line No Longer Available’ error the making calls, you may want to restart your iPhone.

Fix #5: Remove and re-insert your SIM

If you only use a single SIM card on your phone or if your default line for calls and messages is your physical SIM card, then you may want to remove this SIM from your SIM tray. To remove a SIM from your iPhone, insert a paper clip or SIM-eject tool into the hole next to the SIM tray and pull it out. Once out, remove the SIM from its slot, clean it, and then re-insert it accordingly. 

Fix #6: Reset your Network Settings

Since the ‘Last Line No Longer Available’ error points to an issue with your e-SIM, resetting your network settings once wouldn’t be such a bad idea.

  1. Thank You!! I have an Iphone 11 and I switched over to xfinity comcast, for the first time it was doing this, so I clear the call log and it fixed the problem! Thank you!!

  2. Thanks. I have an iPhone 13 and I cleared the recent call log, turned on and off airplane mode and then reset network settings. After all that, normal usage has been restored. 😃

  3. The issue occurred while my friend was trying to call an Android phone. She had no problem after that calling an iPhone 13 user (me). I suggested that she try the Android user after hanging up with me. I thought that having a successful call would reset the phone’s SIM choice. It did. Her call to Android worked. The message went away.

  4. I just got a 12, cleared the call log and it worked!

  5. I just went in and deleted the number from my recent call log that I was having the trouble with and turned airplane mode off and on and that corrected the problem. I did not have to clear the entire recent call log list.
