Imagine this: You are in a hurry to make a call. You pull out your iPhone, dial the number and bam! An error pops up out of nowhere saying “Last row no longer available”. If you are bothered by a similar error message, this guide is for you.
This error essentially forces you to use your chosen default line (primary number) for voice calls or FaceTime calls on your iPhone. That means the default number or line is used to call or message someone, whether the person is in your iPhone’s contacts or not. But if your iPhone cannot recognize that last line (primary number), it will give you this error – Last line no longer available. This mostly occurs when you use the iPhone in a dual SIM mode – regular SIM and eSIM.
We’ve listed some troubleshooting tips that should help fix the last row is no longer available error message on your iPhone in no time. So, let’s get straight to the point.
1. Restart your iPhone
First and foremost, you can start by restarting your iPhone. This should close any background processes or services that might be responsible for the error and fix minor incompatibilities.
If you have an iPhone X or newer, press and hold the sleep/wake button and either volume button for the shutdown prompt to appear. On older iPhones, press and hold the sleep/wake button until the iPhone prompts you to turn off the device.

Wait for your device to fully shut down, then press and hold the sleep/wake button again to turn it on.
2. Delete call log
Next, try clearing the call log on your iPhone to see if that helps. Strangely, several users have reported success in fixing recent line error by deleting call history on iPhone. You can also try.
Step 1: Launch the Phone app on your iPhone.
Step 2: Navigate to the Recents tab and tap Edit at the top.

Step 3: Tap “Delete” in the top left and choose “Delete All Recent” when prompted.


Restart your iPhone and try making a call to see if the error is resolved now.
3. Toggle airplane mode
If the error occurs due to a network issue, you can toggle Airplane mode on your iPhone to fix the problem. This will force your iPhone to reconnect to the network and may fix the problem.
Swipe down from the top-right corner to bring up Control Center. Tap the airplane icon to turn it on. Wait a minute or two and then turn it off.

4. Remove and reinsert the SIM card
If the problem persists, you can try removing and reinserting the physical SIM card from your iPhone. Turn off your iPhone first and then use the SIM ejector tool to pull out the SIM tray. After removing your SIM card, clean it with a microfiber cloth and insert it.

Turn on your iPhone and try making a call again.
5. Update carrier settings
Network operators also update their settings from time to time. Ideally, these updates will be installed automatically in the background. However, if for some reason the update didn’t go through, you can manually install these pending updates by following the steps below.
Step 1: Launch the Settings app on your iPhone. Navigate to General and then tap About.


Step 2: If there are pending updates, a pop-up will appear. Tap Update to continue.
After updating, check if the error is now resolved.
6. Reset network settings
If updating carrier settings doesn’t help, you can try to reset network settings on your iPhone. This will reset all network settings to their default values and fix all network related issues. Here’s how to do it.
Step 1: Open Settings on your iPhone and navigate to General. Scroll down to tap Transfer to iPhone or Reset.

Step 2: Tap on the Reset option at the bottom and select Reset Network Settings from the menu that appears.


Enter the lock screen password to verify your identity. When done, tap the Reset network settings confirmation button to start the recovery process.
7. Update your iPhone
Finally, you can check for pending software updates on your iPhone. If an error is causing the last line error in iOS, updating your iPhone to the latest version should help. Read on to learn how.
Step 1: Open the Settings app on your iPhone and navigate to General.
Step 2: Next, tap Software update and check for newer updates.


Download and install any pending updates on your iPhone.
Most likely, it is a temporary bug where your iPhone cannot identify your SIM card. So you can take it out and give it a good clean with some isopropyl alcohol and a microfiber cloth. Make sure there is no dirt or debris on the SIM card.
