Imessage not working for some contacts following updated phone number

Hey Jebanator,

Did you get a chance to check your number in your iMessage settings as shown in Add or remove your phone number in Messages or FaceTime?

"Set up your phone number

1. Go to Settings > Messages and make sure that iMessage is on. You might need to wait a moment for it to activate.
2. Tap Send & Receive. If you see “Use your Apple ID for iMessage,” tap it and sign in with the same Apple ID that you use on your Mac, iPad, and iPod touch.
3. In the "You can receive iMessages to and Reply From" section, make sure that your phone number and Apple ID are selected.
4. Go to Settings > FaceTime and make sure that your phone number and Apple ID are selected in the "You can be reached by FaceTime at" section."

If that is what you mean by your new phone number being updated, Apple Support will need to assist from here. You can reach out at  Get Support.

Kind regards.

Hi Jebanator,

It sounds like you've tried some good steps already on your own. Let's see if we can help getting all your iMessages to send. If we understand, there is no issue with SMS/MMS messages. After changing your phone number, you do need to update your Apple ID settings.

Manage and use your Apple ID has a lot of good tips for keeping your information updated. Here are two that may be relevant to your situation.

Manage your Apple ID

Because your Apple ID is used across all your devices and services, it's important to keep your account information up to date. Simply sign in to appleid.apple.com  at any time to manage your account:

• Update trusted phone numbers and devices that you're currently signed in to with your Apple ID.

• Change your Apple ID country or region.

– Depending on how you created your Apple ID, you might be required to provide additional information or change your Apple ID username from a mobile phone number to an email address.

If you’re not able to update your phone number there, you’ll want to follow the steps under "Remove your phone number”, then the steps under "Set up your phone number” to add your new one: Add or remove your phone number in Messages or FaceTime

Looking at If you can't send or receive messages on your iPhone, iPad, or iPod touch, see if there are any steps you can try that you haven't already.

You still are unable to send only to a certain few Apple users, you will want to reach out Apple Support by going to Get Support.

We hope this helps.

Take care!

Got it.

Just to confirm, iMessage is working, just not with all contacts, is this correct?

If so, try completely deleting the message with those contacts from the phone and then start a new message thread with them. 

Let us know if this does the trick.

Hey Jebanator,

Thanks for those details.

We'd recommend contacting Apple Support for further assistance here: Get Support
