The phone number "is not registered with iMessage"

Thanks, even now (2018) this worked and solved my issue of texting from my iMac and iPad. I simply followed the same procedure "In iPhone settings, open iMessage. Select Text Message Forwarding. You must be on the same wi-fi network."

Wahoo!

Amazing! After trying to find an answer on the web, I spent about 20 minutes with Apple support on this. They put me on hold, came bock, took off again. Made sure forwarding was on. Finally gave up, said sorry, call Verizon or whatever. The number I was having trouble with is on Cricket. And it was listed as home.

I switched it to "Mobile" and suddenly it works. Don't understand why Apple would this. It's too easy to enter a number and forget to specify which.

Thanks so much for your post. I'm dealing with a contractor who doesn't do email except through his wife's computer, awkward, and I send some fairly long texts, which I don't want to have to do on the phone all the time.

Hi,

I'm also having the same problem. I keep on getting the message ("phone number" is not registered with iMessage) whenever I tried to send an SMS text message from my Macbook Air.

I can't get the text messages from my iPhone 5s to synchronise with iMessage using the latest Yosemite update. On the previous Mac OS X Mavericks, only a few contact numbers worked.

I would greatly appreciate if anyone can help me with this issue.

Cheers,

I have same prob, and Apple said we'd no longer have this problem with YOSEMITE, that you'd be able to message anyone even those without macs or iphones! Amazing it's still a prob. I wonder if they know or anyone else how to fix? So frustrating!

Have you added the phone number to your Messages account?

So how does one do that. It seems the help notes in iMessages do not give complete instructions. The person I wish to message is in my contacts and I can send him msgs using my iphone and ipad but not my computer.

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:"

You must register your phone number by signing into iMessage from your iPhone. If you are already signed into iMessage on the iPhone, sign out and sign back in on the iPhone.

If it still doesn't appear on the computer, sign out of iMessage there and sign back in. It should appear then.

Also, in order to send SMS messages from the computer, you must enable it on the iPhone. In iPhone settings, open iMessage. Select Text Message Forwarding. You must be on the same wi-fi network. Your computer or other device should show in the list. Just click on the device you want to enable.

Also enable SMS on the iPhone.

The problem is not not being able to send msgs at all. I'm doing a fair amount of texting. On my MAC, I cannot send to some people to whom I can text on iPhone or iPad. When I do text them on the iPhone or iPad the msg then shows on my MAC but I cannot send or reply to them on the MAC.

My reply was to the OP.

You say you can't send at all, then you say you just can't send to some. Not sure what you are saying. For the ones you can't sent to: do they have an iPhone or are they registered with iMessage? If not, then those people will be SMS messages. You will need to enable your computer on the iPhone as I described.

If this is not the case and your problem is different than the OP, then start a new discussion stating what your problem is.

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.

Maybe I can be clearer. My iphone shows up in messages on my mac and I can text a large number of person with and without iphones. It's not my phone for which I receive the mmsg not registered but for toehres, their numbers are highlighted in red in the recipient box. My phone and my iphone have no problem texting the same people just my mac.

BINGO, it is the FORWARDING that I needed to add, thank you! now I can text from Mac's iMessage to non iPhone users :-) easier on the eyes and fingers!

grazie grazie thankyou
