Why do my texts keep switching between RCS and SMS on iPhone?

I’m trying to talk to someone over text who has an android, but every text i send is being sent as SMS and all of theirs are being sent as RCS. It keeps flipping back and forth and it’s annoying.

This finally worked for me!

“You are going to want to turn off RCS in your Messages settings, then turn on Airplane mode. After that, restart your phone. Then go back in, enable the RCS setting and THEN turn off Airplane mode and it should work.


This is assuming you have the bug where your contact’s messages come through as RCS, but yours still come through as SMS. And make sure they are the one who sent the most recent message, so the latest chat came through as RCS.


If you’re not already receiving as RCS, I don’t know if this will work. Apple pls fix”


***!!! This is the only thing that worked for me! I reset network settings, restarted, turned off iMessage, SMS and did everything else suggested in this thread and finally the airplane mode with RCS disabled restart worked for me. THANK YOU!

Notice how, on this site hosted by Apple, no help or suggestions are given by anyone from Apple. I think that's pretty lame.

I hope this is enlightening:


Like just about every large company Apple has both formal technical support and an area where users can discuss technical issues with other users. And, like all of those other companies, Apple does not participate in any significant way in the user-to-user discussions, as that might inhibit the free flow of ideas. The formal name of this area is Apple Support Communities. The “Communities” should be a giveaway that this isn’t a formal support site. And if that doesn’t, the site itself is https://discussions.apple.com. The “discussions” is another giveaway.


Apple’s formal support can be reached several ways

  • You can provide feedback to Apple at→ Product Feedback - Apple where your issue or suggestion will be recorded, tracked and matched with similar reports, but you will not get a reply



For personalized support

Best way: 

  • Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) access to diagnostic data on your device



Other options:

(Note that both of the above have options to receive a callback or chat)



About the only communications methods not used by Apple support is inbound email or text, probably because the volume would be overwhelming, and separating the wheat from the chaff (or, to us engineers, a poor signal to noise ratio) would be almost impossible.

And yet, I don't suggest the initial label, of "phone", the device does during initial save.

It's also not selectable again, because it isn't in the list at all, after.


This is a vCard standard formatting issue.


As soon as I change the label to one that exists from the list, either while storing the contact initially or once RCS breaks, it immediately restores RCS.


For the two contacts this had been happening the moment I picked a label that actually existed in the list, RCS worked. When I deleted then re-added the contact with the default "phone" labels, RCS broke.

Not here to argue, sharing what worked and reliably. What's your suggestion?
