    I am having an issue with SMS relay to my iPhone 5s from my MacBook Pro (2015 model running OS Sierra). Basically it used to work but now it does not. My Mac is not receiving SMS messages sent to my phone, nor can it send an SMS message through my phone to another person. What confuses me is that this was working just fine before and as far as I know none of my settings have changed. Does anyone here have a solution to this problem?

    When I try to send SMS from my mac it highlights the number in red like the picture below and cannot send it.

    I know this is a common issue and I have read a number of articles and proposed solutions to this problem, but none have worked in my situation. Most of what I have read says to go into settings-messages-send & receive on the iPhone to activate your email account, however mine is already active and as I mentioned SMS forwarding had worked until just recently. When I go into "text message forwarding" in the same messages menu and deselect my MacBook and turn it back on nothing happens. It does not request or produce a code on my Mac. These are the only two solutions I can find and they aren't working. Is there another issue I am not aware of here?

    The only possible thing I can think of that may have caused this problem is that I recently updated the carrier settings for my iPhone. Would that have an impact on SMS relay?

    I appreciate your help.

    I am having the same problem, since about the 22nd December. I have an iPhone X (iOS 11), an iPad Air (iOS 10), a Late-2013 rMBP (High Sierra) and a 2017 MBP with TB (Sierra) and text messages from the iPhone have stopped relaying to all of them. I'm not aware of having changed any settings, it seems to have just stopped working overnight.

    Like you, despite trying several things and reading semi-unrelated articles, nothing works. I get the same 'nothing' when flicking the switches in 'Text Message Forwarding' as well.

    Perhaps there is a bug in the latest iOS?

    EDIT: I have just realised that SMS messages are being forwarded from my iPhone to my rMBP running High Sierra, but not the MBPwTB or iPad Air that are running older operating systems - perhaps that is the issue? I am surprised that Apple did not say anything if that is the case (or, maybe these days I'm not..)

    Updating the Touch Bar MBP now to see...

    EDIT EDIT: Accidentally put my Touch Bar MBP to sleep while the update was downloading. Couldn't resume it, so rebooted and now SMS messages are forwarding to it correctly, even though it is only running Sierra...

    EDIT EDIT EDIT: SMS are now also correctly forwarding to my iPad on iOS 10, which has not been rebooted. How strange.

    You didn't mention if you tried signing out of iCloud everywhere on all your devices and then signing back in.

    No I did not, I specifically wanted to avoid that headache. The only thing I signed out of was iMessage on my iPhone, left it for a few minutes, then signed back in.

    I’m having the same issue. SMS relay seems to have stopped sometime after 5th January as that’s the last one I have on my MacBook Air running Sierra. iMessages still sync fine. I tried switching off text message forwarding to my Mac but not can’t turn it on. I flick the switch on my iPhone and Messages opens up on my Mac but no code ever appears. I also forward to my iPad Air 2 running iOS 9. I switched off forwarding on my phone for that and switched it back on and it showed the code correctly . I’ve made sure my iMessage setting are the same on both phone and Mac both use my mobile number and email address.

    I have had the same issue. The last SMS message to my Sierra 2012 MBP was late December. SMS still goes to my iPad, though. I've rebooted it, tried to set it up again, etc. Nothing. Any other ideas?

    See this solution found at apple forum :

    "I fixed this by finding an SMS text message thread and responding to it. After doing that, I started to get all of my messages again. For the phone calls, I placed a call using my Macbook and that triggered things to work again."
