Also contact your carrier, in case this is a known issue from their side.

Maybe this will work for some. Somehow to iOS and OSX 27 I too lost SMS txting from my Macbook Air. Spoke to apple. Somehow it was easy as going to messenges>settings>iMessage and singing back in on both devices. (how this effected SMS txting, dunno.) if you have to wait a second or two after tapping iMesseges till you see a list of all your available phone #'s and emails for outgoing/incoming do so before tapping sign in. Give it a try?

(also if your audio calls are not coming through on the computer... same process just under the Facetime app settings on phone, signed out again. This all worked seem-less prior the update to 27.0.1)

you'll never get an explanation of why or how many people experience this in the software update.

Same issue for me. The users that are having trouble are ones I have not messaged before and are not in my contacts. I am not getting a number of 2-factor auth codes from companies and had to switch to Google Authenticator for one. Also had an Android user today who texted me and I didn't see it. I texted her and then she texted me back and I could see it. But her 1st text never came through. Not sure if this was during 27.0 or 27.01 that it started but it is definitely since upgrading to iOS 27. I have an iPhone 14 Pro and tried all the reset messages options.

Thanks for responding back with a follow up question. 🤗

Rich Communication Services (RCS) is an advanced mobile messaging protocol that was not developed by a single company, but rather by the GSM Association (GSMA), a global trade organization representing mobile network operators worldwide.

This is out of Apple’s control and cannot be responsible for updating their network protocol.

Thanks again for reaching out. 👍🏼

Take care! 👋🏼😉

The suggested fixes not working for non iPhone users. It still shows as offline and non iPhone must use RCS. Perhaps Apple should troubleshoot these matters prior to pushing updates. 😤
