Part 1. Common Cases of iMessage Not Delivered iPhone

The function of iMessage is not only convenient and fast but also secure and reliable, making it the best choice for Apple users for daily communication. But nowadays, this feature has some issues. Here are three typical cases.

Case 1. iPhone Rings But iMessage Not Delivered

One Apple user complained "My text hadn't been delivered. I called them just to make sure I wasn't blocked and it rang the normal amount of times." Are you falling into the same situation as this? Perhaps you're able to call your friends or family, but you may find you're blocked from sending a message to them. This may result from your unstable and poor network. By changing the internet, you may solve it.

Case 2. iMessage Say Delivered on Mac But Not iPhone

Another case is the iMessage says delivered on Mac but not on iPhone. This is a common bug in the Apple system. This situation occurs when you have multiple devices logged into iMessage and then you send a message to another iMessage user. It may be the recipient is not connected to the iMessage server. That's to say, the iPhone has no signal or power.

Case 3. iMessage Says Delivered on iPad But Not iPhone

Have you ever found your message delivered on iPad but failed on iPhone? What is the exact reason for this? Actually, this is similar to case 2. Even though you check other devices and the message shows "Delivered", you haven't sent the message in fact if your original device failed to send. It's due to delay or you haven't set up your iPhone correctly.

Additionally, you can also see the start and end times of the problem repair. So if the iMessage is under repair, it will affect your message sending.
