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!

This is happening to me as well since the ios 18.1.1 update last friday. Sometimes I send a msg and it goes by RCS but mostly its going by sms. My boyfriend's msg are coming to me as rcs but when i reply it sends as sms. Prior to the ios update everything was by RCS both ways with zero issues. I wish I hadn't updated the ios...Apple needs to fix this crap

I had the same issue my girlfriend had a iPhone then switched to Android my iPhone 15 was sending RCS fine until it kept sending as SMS


If you have dual SIM have BOTH ON WHILE RCS IS ACTIVATING AFTER NETWORK RESET I have a T-Mobile SIM for backup and Verizon as Primary make sure your second SIM is the one using for Cellular


Before you reset network iCloud backs up any saved Bluetooth and Wi-Fi networks

Make sure your second line is used for data

THEN reset network

Having this issue too and sometimes resetting all network settings will fix it, but it seems like moving between wireless and cellular, particularly if I go outside my house where wifi starts getting weak 'triggers' the issue for a particular contact. One time I told it to send as SMS when a normal RCS message didn't go through and now it just wants to always do that for this one contact. Super frustrating.

Yes, after I reset my networks it's always worked. I'm using a 15Pro on ios 18.3.
If yours does but only temporarily I suspect it's your cell provider's fault. It's also possible it's an ios bug, that's why I don't update anymore unless absolutely necessary.

It works just fine on my iPhone 15 Pro with iOS 18.5. But I would have updated any way. The security updates are important.

I think I figured out the trigger.

The affected contact(s), when originally stored (via add new contact from within the Message app) are of type "phone":


But that label type does not exist.

So once the RCS function stops, only switching this label to any existing from the list, restores RCS. I assume that when the contact is initially saved, it's a currier label "mismatch" of some sort.

Both my wife and I have turned it off on our iphones but there is no way to turn it off on her ipad

You can't turn it off on your iPads because iPads aren't capable of either SMS or RCS. You can have both types of messages forwarded from your phone. If you turn RCS off on your phones, you won't get them on your iPads.

but still, others who group text are using RCS and/or haven't updated to the latest iOS and that is their right to do so

They can also turn it off if they want to.

as long as they exist on the group the issues persist

That's really an SMS/iMessage issue.

And no I am not blocking my family or telling them to turn it off

Why would you have to do that? If you turn off RCS, messages from people using RCS will be delivered to your phone using SMS/MMS.

Apple should make RCS work regardless of the situation

RCS is not an Apple protocol. If you want to use something that Apple has control over, use iMessage.

RCS is just poorly implemented and causes a lot of problems

You seem to be in a minority. For most people, it solves a lot is issues.
