The phone number "is not registered with iMessage"

Finally got husband's phone working with iMessage, but not sure how it happened. I had him check that "send as SMS" was on. It was. Then I had him toggle the iMessage slider button. Then I had him send me an iMsg, which I received on my iPhone in a gray bubble. Then I sent him a test iMsg which appeared in a blue bubble. Voila! Angry unsent messages on iMac iMessages were suddenly sent and appeared on my screen in beautiful blue bubbles.

Go figure.

Have a nice day.

I cannot text from my computer and I did everything that was suggested. However, when I turn on the computer from my iPhone i recieve a message that a code was sent to the computer and I need to enter the code. However no code is showing up anywhere on my computer?? Any suggestions?

So if my Mac is not connected via Wifi, but by ethernet instead, then the above referenced process won't work?? I've switched on the "Text Message Forwarding" on my iPhone several times, but not code is ever sent to my Mac. I can confirm that the iPhone is working in that regard because I can send the code to an iPad.

I've been on my phone and cannot find the 'Text Message Forwarding' option under Settings>Messages>... Has this changed?

All I have are as follows:

============

iMessage - on/off

Send Read Receipts = on/off

Send as SMS = on/off

Send and receive = My phone number displayed.

sub menu:

User your Apple ID for iMessages

You can be reached by imessage at... (my phone number displayed with check mark next to it)

MMS Messaging= on/off

Group Messaging = on/off

Show Subject Field= on/off

Character Count= on/off

Blocked= on/off

Keep Messages = Forever

Filter Unknown Senders= on/off

(Audio Messages) Expire = After 2 minutes

(Audio Messages) Raise to Listen

(Video Messages) Expire = After 2 minutes

===============

That's it. Where is this Text Message Forwarding option?

I get that error message when trying to use the Message app on my Mac - to my daughter's iPhone. I don't get it when using the Message app on my iPhone to her. I don't get that error when sending messages to my granddaughters from my Mac nor my phone - messages sent to from either also show up on my other device. This error is only a couple of months old. It used to work the same as my granddaughter's messages.

I don't see any difference between their contacts that would explain this.

I am having these problems too. On my Mac, I am running Sierra (10.12.1). On my iPhone SE I have iOS 10.1.1. I imagine things may be different as a result. But when I try to set 'Allow Calls on Other Devices' on the phone, I am told that FaceTime and iCloud must be signed in to the same Apple ID' — and they are, but it won't let me set this.

This same problem recurred again for me (iphone SE, iOS 10.2.1), curiously enough after I had updated my macOS on my desktop Mac to 10.12.3. After an online 'chat' with an Apple advisor, I looked on my phone at Settings/Messages. On my iphone SE, Text Message Forwarding is the second item down, and on touching it, it turned out that it had mysteriously been toggled 'Off' without my having touched it. Talk about connectivity!

But toggling it back 'On' restored my SMS messaging as well as imessaging.

It seems that if one types a message on one's Mac to someone who is not imessage-enabled, it first goes to one's own iphone, which converts it to SMS and sends it on to one's addressee. Or am I making that up?

this is what worked for me too. i also turned lots of the settings off and on. signed out of my apple account on my phone in messages and on again. I basically did everything but also turned all the messages off and on but the one thing that worked was actually turning Facebook off and on again

I called Apple Support. After spending time going through the lower level advisor, then being transferred to a senior level advisor, I discovered the problem and simple solutions.

Problem

The iPhone can send message via iMessage or SMS ( SMS for non Apple phone like Android)

The Mac can only send message via iMessage NOT SMS. So you can't send messages directly through a Mac to a non apple phone.

Solution

If you link your iMessage on your Mac, to your messages on your iPhone , you can send messages on you Mac to non Apple user, as the message will be automatically be routed through your iPhone and be send as SMS.

This is How to Link Mac Messages with iPhone Message

On your iPhone (not your Mac)

Go to "Settings"

Go to "Messages"

Go to "Text Message Forwarding"

Turn on your Mac to allow linking

This should work - It solved my problem.

Have you added the phone number to your Messages account?

Messages/Accounts/Message Account/Settings - click add e-mail and enter the phone number.

Where do I do this on the MAC? In the app there is no account/message Account/settings.

Open Messages, click Messages>Preferences, open your Apple ID account within, on Settings tab add phone number in "You can be reached for messages at:"

Your solution worked for me. Don't know how it got turned off. I'm sure I did it somehow. But now that the computer is enabled Under Text Message Forwarding, everything is back to normal.
