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.

For users who get the ‘Last Line No Longer Available’ issue on your iPhone, you might want to look into the possible fixes required to make the problem disappear. If one doesn’t work, you can keep moving on to the next until the issue is entirely resolved. Let’s find out all the solutions to help you solve your problem.
Disable Wi-Fi Calling
When you connect your iPhone to Wi-Fi, it uses that connection to make and receive calls instead of using your mobile data plan. This is what leads to the last line no longer being an available issue on certain iPhones.
By disabling Wi-Fi calling on your device, you can eliminate this problem and use your Phone as a phone again.
Clear Recent Call Log
If you have recently cleared the recent call logs on your iPhone, you might have found that the last line no longer available issue is still there. This is because the recent call logs are stored on a different file than those that store your contacts.
If you want to resolve this issue, follow these steps:
- Go to Settings and select Phone.
- Scroll down and select Call History. You will see all of your missed calls listed here.
- Select a particular day from the list of days to view your missed calls for that particular day.
- You can select and delete them to resolve the issue!
Switch Between SIMs
The line no longer available issue is a common problem that many iPhone users encounter. It is a problem that you can try fixing by switching between two sims.

Enable Airplane Mode and then Disable it
Sometimes your iPhone may face network problems that can occur for numerous reasons, and the simplest way to fix the issue is by enabling airplane mode on your iPhone. When this occurs, your iPhone loses all connection with its cellular network. As soon as you disable it, the network connection gets re-established.
Now with airplane mode help, you can resolve the last line no longer available issue by turning off all the wireless connections in your iPhone. To turn off all the wireless connections on your iPhone, open up Settings and scroll down to Airplane Mode. Please turn it on and then disable it again.
Update Carrier Settings
In order to connect your iPhone with its mobile network, users must have the right carrier configurations, which help communicate with the network provider. Even though your iPhone has the carrier settings enabled the moment you open your Phone. Eventually, network providers update the settings to make the connection even more stable and secure for users. If the ‘Last Line No Longer Available’ issue shows up on your phone, it’s because of the bug inside your carrier’s configuration. So to solve this, you can install the updates for your carrier settings from your network provider.
In order to update carrier settings on iPhone, please follow the steps below:
- Open the Settings app on your iPhone and tap the “Cellular” option.
- Tap the “Carrier Settings” option under the Cellular section and tap “Update Carrier Settings.”
- Now, it will take you to a new screen where you have to enter your current carrier details and tap “Next.”
- Finally, it will take you back to the previous screen with updated carrier settings.
Remove Your SIM and reinsert it
If you have one SIM card on your Phone and your physical SIM card is your default line for phone calls and text messages, you may intend to remove your SIM from your SIM tray. Slide a paper clip or SIM ejecting tool into the hole next to the SIM tray; this will help pull the SIM out from your iPhone. Remove the SIM card from its place, clean it, and reinsert it as needed.
Update Your iPhone to the Latest Version
The last line no longer available issue is a problem that many iPhone users face. It happens when the last line of a text message, email, or other content is cut off in the middle because of the latest update.

If you are having trouble connecting to Wi-Fi or cellular data, resetting your network settings may help with the last line no longer available issue. Resetting network settings on iPhone is quick and easy. To do this, go to Settings > General > Reset > Reset Network Settings.
Method Of using an eSIM
An eSIM serves as a digital SIM. It enables you to make use of a mobile service plan provided by your network provider without the requirement of a physical nano-SIM.
- What is required in order to set up an eSIM
- A later model iPhone (XS, XS Max, or XR) with iOS 12.1 or later.
- A wireless network provider that is capable of supporting electronic SIM cards.
- Note that both SIM plans must come from the same network provider unless your iPhone can be unlocked so that it can be used with a different network provider. The electronic SIM card and how to use it
In order to make use of an eSIM, you will first have to activate it by following the steps that appear on-screen. You can activate the eSIM in many different ways, including using an app provided by your carrier, scanning a QR code, inputting the eSIM information manually, or activating it through the eSIM carrier.
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.
How to avoid experiencing the problem “Last Line No Longer Available” occurring again in the future
If you’ve tried all of the options that were stated above and the ‘Last Line No Longer Available’ problem is still appearing on an iPhone 13, there are a number of things that you can do to avoid it from happening again in the future.
First things first, check to see that your iPhone 13 is running the most recent version of iOS available at all times. Simply navigate to Settings > General > Software Update in order to check for available updates.
Second, check to see that the settings for your carrier are as recent as possible. You can make changes to your carrier settings by navigating to Settings > General > About on your device, then scrolling down until you see the Carrier option. After selecting a carrier, wait for the iPhone 13 to perform a check for software updates. In the event that there are any updates available, they are going to be downloaded and set up automatically.
Third, check to see that all of your contact information is saved in iCloud. You are able to confirm this by navigating to Settings > iCloud > Contacts on your device. You can turn on iCloud contacts for your contacts even if they are not already saved in iCloud by pressing on the switch next to Contacts.
Fourth, check that you are connected to a reliable Wi-Fi or cellular network connection. It’s possible that your iPhone 13 won’t be able to make or receive calls if you are using a weak Wi-Fi or cellular signal.
Lastly, if you are protecting your iPhone 13 with a case, check to see that the SIM card slot is not being obstructed in any way. Your iPhone 13 won’t be able to make or receive calls if the SIM card slot is blocked.
