Whether you have ever used iMessage for instant communication or not, it gets really annoying if it suddenly stops working.

So, this guide covers iMessage problems, their causes, and fixes for iPhone, iPad, and Mac.

iMessage Not Working? Here’s How to Fix Common Problems

Common iMessage Problems and Their Causes

iMessage is a strong, trustworthy service. However, no technology is perfect, so it may encounter problems at times. Therefore, the first step in resolving a problem affecting you is to understand its underlying cause. Finally, the most common problems are explained in detail.

Activation Errors

Any issues that prevent iMessage from connecting to the correct account on your iPhone, iPad, or Mac are called activation problems. These typically show up as messages like “Waiting for Activation” or “Activation Failed.” Causes can range from poor internet connection to incorrect date and time settings. As a result, iMessage won’t work until it’s activated properly.

Messages Sending as SMS

Sometimes, iMessages can switch back to SMS, which you identify by green text bubbles instead of blue. Indeed, this usually happens when iMessage systems are down or your internet is poor. So, that means messages will still reach their place. However, SMS lacks read confirmations and security. Therefore, users lose iMessage’s features.

iMessage Not Working with Specific Contacts

The annoying part is, that iMessage works perfectly with some contacts and not with others. So, this might happen if the person you’re messaging turned off iMessage or is not available from Apple systems. Also, wrong contact details, like old emails or phone numbers, might be a cause of talking problems.

iMessage Not Syncing Across Devices

Probably, one of the most useful features of iMessage is sharing messages across devices. However, different sharing problems prevent messages from appearing on all devices linked to the same Apple ID. In many cases, the common cause may be the wrong configuration of iCloud or lack of permissions. Also, some devices may have old software.

Internet or Network Issues

Wi-Fi has to have a stable internet connection, or this will not work with iMessage. Moreover, if the Wi-Fi is weak, the mobile data fails, or the network has many restrictions, iMessage will stop working.

Incorrect Settings

Wrong iMessage settings, like different Send & Receive settings, can cause messages to fail. Also, this can also happen if someone turns off the service.

Carrier-Related Issues

If your service provider does not fully support iMessage, then you will face problems in turning on or sending messages. Moreover, the not compatibility of carrier-specific updates or the lack of an active SMS plan is also bound to interrupt the service.

Software Bugs or Outdated iOS

Problems in older iOS versions may be the issues that stop iMessage from working. Moreover, usual updates not only fix problems but also improve how things work together and security
