iMessage Not Syncing Solution #1. Check if it is Enabled

Before you complain about iMessage not syncing, you should first see if it is enabled in the first place. This is the most common mistake of users, they haven’t enabled iMessage but expect it to work.

Below are the steps to enable iMessage syncing for iOS devices and Mac:

  • iOS Devices. Open the Settings Now go to Message and turn the slider beside the iMessage option so it becomes green.
  • Open the Messages app. Now click on Messages from the menu bar and go to Preferences > Accounts. Now select iMessage from the list of Accounts and make sure that your Apple ID is entered and the box is checked.

Check iMessage is Enabled

Once you have done this, iMessage should work properly. If it didn’t, then we really are dealing with an issue here. So you will need to do some troubleshooting.

iMessage Not Syncing Solution #2. Enable iMessages Again

Enabling iMessage on your device is good and all, but iMessage not syncing can happen even with a properly set up device. That’s why some users tried turning it off and on again, and somehow it worked.

Although the reason is unclear, it may have something to do with the device not being able to recognize that the feature is enabled, so you have to do it again.

Since you already know how to turn it on, you should know how to turn it off. Simply turn it off, wait for a bit, and then turn it on again. Afterward, check if the error still persists.

If so, then you may also try another method that follows the same concept.

iMessage Not Syncing Solution #3. Sign Out and Back In

As you already know, in order to enable iMessages, you have to have an Apple account, and you have to use that account to sign in to iMessage. This applies to both Mac and iOS devices.

Usually, you are automatically signed in to your Apple ID once you enable iMessage, that’s why you might not know how to log in, which is not good this may be the reason for iMessage not syncing.

Below are the steps to sign out and sign in to iMessage with your Apple ID:

  • iOS Device. Open the Settings Go to Messages > Send and Receive. Tap on the Apple ID that you’re currently using and select Sign Out. Now tap on Use Your Apple ID and enter the credentials for your Apple ID to sign in again.
  • Open the iMessages app. Now click the Messages tab and go to Preferences > Accounts. There, select the Apple ID that you want to use and click on Sign Out. Once that’s done, sign in with the same Apple ID that you logged out of.

Sign out and Back in iMessage

By signing out of the account, you are resetting the settings that were set on iMessage to default. So by signing in again, you are technically turning everything back to normal and hopefully, this will be the end of iMessage not syncing.

iMessage Not Syncing Solution #4. Verify Phone Number

Have you ever visited the official Apple website to check if everything is in its proper place?

If not, then perhaps you didn’t know that you have to verify that the phone number you use on your device is associated with your Apple ID. If you didn’t know, then it’s time you did, since it might be the key to stop the iMessage not syncing issue.

Below are the steps to verify your phone number:

  1. Open a browser on your device.
  2. Go to the Apple
  3. Log in to your Apple ID.
  4. There will be lots of things here, but what you want to look at would be the Phone Numbers Here, you will see the phone numbers that you’ve verified before.
  5. If you can’t see your phone number, enter the phone number on the Mobile Phone
  6. Click on Save Changes once you are done.

Verify iMessage Phone Number

Once you’ve done this, try disabling and enabling the iMessage again. This will make sure that any change that you’ve done is really saved into the system. Now check if you’ll no longer see iMessage not syncing.

iMessage Not Syncing Solution #5. Check Email Address

In addition to a phone number, you should also ensure that the email address associated with the Apple ID is correct. So how can you check the email address?

  • iOS Device. Open the Settings app and go to Messages > Send & Receive. You should be able to see the list of emails somewhere on the screen. If you can’t find what you want to use, tap on Add Another Email… Make sure that there is a check on its left.
  • Open the Messages app. Click Messages from the menu bar and select Preferences. Go to the Accounts tab and make sure that the email address is listed here. Click on the Add Email button if you can’t find the correct email.

Check iMessage Email Address

Remember that one email address and phone number can be used at a time, though you can enter others so it is already set up in case one doesn’t work.

iMessage Not Syncing Solution #6. Enable FaceTime

While you may think that enabling iMessage is already enough, think again. You should also make sure that it is properly set up, and that can be done with these steps:

  1. Open Settings.
  2. Go to FaceTime.
  3. Turn off FaceTime so it doesn’t appear as a green slider.
  4. Restart your device.

Enable iMessage Face Time

Since FaceTime is sometimes required by some devices, this may be what will help you see the end of iMessage not syncing. You may also try turning it off if it is already turned on the first time you went to this setting.

iMessage Not Syncing Solution #7. Enable Handoff

In addition to FaceTime, there’s also Handoff, a feature of Apple that allows you to leave what you’re currently doing on one device and continue it on another. Basically, it’s another feature that has something to do with syncing.

Although it was not meant to be, some users have reported that enabling this will help solve iMessage not syncing.

Below are the steps to enable Handoff:

  • iOS Devices. Open your Settings. Go to General > Handoff. Turn the toggle On for Handoff so it becomes green. Restart your device.
  • Go to the Apple Menu. Select System Preferences and on the General tab, turn on the slider for Handoff.

Enable Handoff

Although it is a free feature, you have to enable WiFi or at least have a stable internet connection to use this. This shouldn’t be a problem though, since using iMessage must mean you have internet.

iMessage Not Syncing Solution #8. Clear Up Some Space

Your last resort is to delete some threads on the iMessage app, mostly those that are old enough that you no longer remember them. So why would you need to do that, you may ask.

Experts have found out that iMessage not syncing might have something to do with storage space. Since iMessage is without a doubt an app, it may have some limits on how many threads it can store. As such, you should try deleting threads.

Unfortunately, this is a bit risky, hence why I saved this for last, but it shouldn’t matter much for the price of seeing the end of iMessage not syncing. After all, you’re only deleting threads that are no longer necessary.

Avoid Data Loss by Backing Up Your Messages

Although we’ve already discussed the last resort, the actual last resort is actually resetting your device so that iMessage can work properly again. However, that may lead to data loss, and that’s when FoneDog iOS Data Backup & Restore comes in.
