In this troubleshooting guide, we will show you what to do if iMessage stopped working on iPhone 12 after the iOS 14.3 update. Being one of the high-end devices, your iPhone shouldn’t have problems sending and receiving text messages. But there are owners who have encountered such an issue. If you’re one of them, then this guide might help. Continue reading to learn more about it. 

Being a core service, iMessage should work properly on your iPhone, but it seems like there are some users who encountered some issues with it after the iOS 14.3 update. Most of the time, this kind of problem is pretty minor. So if you’re one of them, here’s what you should do: 

First solution: Disable iMessage and do the Forced restart

It’s possible that this problem is just due to a minor issue with iMessage, or even a firmware glitch. So the first thing you need to do is to disable iMessage, and then refresh your phone’s memory. Here’s how you do it: 

  1. Launch your iPhone’s settings app. 
  2. Scroll down and tap Messages. 
  3. Tap the switch next to iMessage to disable it. 
  4. To force restart your device, quickly press and release the Volume Up button, and then the Volume Down button. 
  5. Immediately after that, press and hold the Power key for 10 seconds. This will trigger your iPhone to shut down and power back up. 
  6. Once the Apple logo shows, release the power key and allow the device to continue the boot process. 

After the restart, try to see if your iPhone 12 can now send iMessages. 

Second solution: Make sure you have a stable Internet connection

Another thing you have to look into is your internet connection. You must have a stable connection to be able to send and receive data smoothly and quickly. It’s possible that this problem is caused by a connection problem. 

So check if your iPhone 12 is connected to your own network. 

After that, try doing a speed test to confirm the speed and stability of your internet connection. 

Assuming you have a fast and stable connection yet your iPhone can’t send i-messages, then move on to the next solution. 

Third solution: Reset the network settings of your iPhone

After doing the first and second solutions and your iPhone 12 is still not able to send i-messages, then it’s possible that the problem is with the network services of your device. So you need to reset just the network settings to rule out such a possibility. Here’s how it’s done: 

  1. Launch the Settings app. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Touch Reset Network Settings. 
  5. If prompted, enter your security lock. 
  6. Tap Reset Network Settings at the bottom of the screen. 

After doing this, try to see if the problem is fixed. 

Fourth solution: Factory reset your iPhone

If for some reason the problem persists even after the previous solution, then you have no other choice but to factory reset your iPhone. A reset will be able to fix such a problem, but make sure to back up your important files and data as they will be deleted. When ready, follow these steps to reset your device: 

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Tap Erase All Contents and Settings. 
  5. Tap Erase Now. 
  6. If prompted, enter your security lock. 
  7. Tap Erase iPhone at the bottom of the screen.  
  8. Tap Erase iPhone again to proceed.  
  9. Now enter your Apple ID password, and then tap Erase to proceed with the reset. 
  10. Wait until your iPhone has finished the reset, and then set it up as a new device.
