Resolved Message Send Failure for Mac SMS after switching phone providers?

[mrbobdobolina]

I have a Mac Studio and for the last year I've been able to send SMS messages (usually responses) via the message app on my computer.

I get a "Message Send Failure" error.

My troubleshooting steps so far:

• rebooted computer. (Mac Studio, macOS 12.6.6)
• logged out of my Apple ID inside the Messages/iMessage preferences on the computer.
• rebooted again.
• on my iPhone (12 mini, if it matters, OS 16.5.1(c)) went to Settings -> Messages, turned on "Send as SMS" which was off, and toggled Text Message Forwarding off, then back on, for the mac in question.
• tested my other mac and it too would not send. (iMac macOS 13.4.1)

This only is affecting my ability to contact non-iMessage users. (Green bubbles.)

I recently switched my phone provider, and it's possible (probable?) that this started happening when I made that switch. (Switched from Visible [who I actually really liked] to Mint Mobile [because it was quite a bit cheaper].) I kept the same number.

Anything else I can/should try to get this working again?

Thanks in advance.

Try going to Settings > Messages on your iPhone and cycling Text Messages Forwarding off and on.

Thank you!


As I went back to toggle this option I realized that Send & Receive iMessages had been unchecked for my phone number. Not sure how or why, but after enabling that everything works as expected!
