The phone number "is not registered with iMessage"

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.

What worked for me was going into settings on the iPhone, turning FaceBook Off and then turning it back On... then doing the authentication thing (I have two factor authentication turned on).

This worked, mostly. For some reason when the icloud update happened a few weeks ago it kicked me off and this path helped me find how to log back in with messages. Thanks!

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.

Replying to myself, I followed Glenn's instructions (above, in this string) and it's all working now. I am even able to text people with mobile phones other than iPhones. Thank you, Glenn.

I have read all the replies. Cannot find text message forwarding on my iPhone message settings

Michael,

Thank you, thank you. My message forwarding WAS toggled off. Turned it on and viola! Everything now works!

Read Michael's post. It fixed my problem!

I'm having the same problem on my iPhone 6s. I checked in iMessage on my iPhone like Glenn said and there is no Text Message Forwarding.

Apologies! I was getting confused with Call Forwarding. Ignore what I said in my previous post; it's under Settings/Messages. It's the second item down in that menu on my phone.

I've tried this now. Repeatedly. It is still not working on my MacBook Pro. I can message people with Apple products, but SMS from iMessages is not working. Any other suggestions?

Thank you,

You were very clear in your explanation. It helped a lot!! Thanks😎
