iMessage is a commonly used tool for iPhone users to communicate with friends and families. When the error: iMessage not delivered on iPhone occurs, don't freak out. Many users have run into this problem. This article provides you with all potential causes and comprehensive troubleshooting. If you don't want to waste time to troubleshoot, we also provide a universal solution in Part 5.

Part 1: What Does It Mean by iMessage Delivered

Let's first make it clear what iMessage delivered means.

First, the iMessage delivered does not equal what will be shown on your family or friends' phones. It just means that your iPhone has delivered this message, and the other person's phone didn't refuse to accept it. If the other person turns on airplane mode, they can only see this message after airplane mode is off, although your iPhone says iMessage was delivered.

Similarly, if your iPhone iMessage is not sending, it may indicate that your iPhone failed to send it or that the other person's phone refuses to accept it. Therefore, according to the two leading directions, there are solutions below.

Part 2: Troubleshoot iMessage not Delivered: Check Internet Connection

When iMessage is not working on an iPhone, the first thing we should check is the internet connection because iMessage is delivered depending on the network. We should check the internet connection first, and if our iPhone internet connection is fine, the issue may occur on the other person's phone's internet.

How to check internet connection on iPhone:

Unlock your iPhone and see the internet signals on the top. If the Wi-Fi signal and cellular signal are both three bars, they are connected stably. Otherwise, they are unstable. Then, go to Settings, tap Wi-Fi or Cellular, change to a stable network and try again.

Part 3: Troubleshoot iMessage not Delivered: Restart iMessage

It's good to know that iMessage is not turned on by default on your iPhone. Even if you once turned iMessage on manually, after factory resetting your iPhone and removing and changing your SIM card, you have to turn it on again. Therefore, we'd better check the iMessage status and turn it on or restart it when our iMessage is not delivered on iPhone.

How to restart iMessage on iPhone:

Open the Settings app on your iPhone and tap Messages. Make sure iMessage is turned on. If it was already on, toggle twice to reactive it. Besides, you must ensure your phone number is checked in the Send & Receive section under iMessage. This is also the key to delivering messages successfully.

Part 4: Troubleshoot iMessage not Delivered: Send As SMS

If you tried the methods above and your message still can't be delivered when you try again, sending it as SMS is the last option. This is because the other person may not use an Apple device, so you can only send SMS messages, not iMessage. You can also send it as an SMS when your or the other person's phone has an intermittent and fluctuating network.

How to send iMessage as SMS:

When your iMessage is not delivered but blue, you can go to the Settings app, tap Messages, and then toggle on Send as SMS. After that, go back to iMessage and try sending your text again. Your message will be sent as green.
