Can't find RCS messaging option on my iPhone 15 after iOS 18 update

Apparently it’s only available in the US on certain carriers. Another waiting game. Sour..

I have the same issue, I am in South Africa and Vodacom do support RCS however that option is not available

Option to enable RCS message in iOS 18 is not available in India.

I’m in Australia and it does not appear anywhere on my iPhone 16 but says it is there when I search for it. Annoying as.

Recently upgraded to ios 18 (with iPhone 15). I was trying to enable RCS messaging but cannot find it in settings. When type rcs in search bar of settings, it shows me one result that sends me to Apps -> Messages, where the switch for RCS should be (above MMS). But it’s not there. I also checked the release notes and rcs update is not region dependent.

your phone carrier would also need to support RCS.

Choose other devices for SMS, MMS, or RCS messaging

If you haven’t turned on Messages in iCloud, you can set up your iPhone so that when you send or receive an SMS, MMS, or RCS message, it appears on your other Apple devices.

Note: Availability varies by region and carrier.

1. Go to Settings  > Apps > Messages.
2. Tap Text Message Forwarding, then turn on any devices you want to include.

Note: If you’re not using two-factor authentication, you need to enter a six-digit activation code that appears on the other device.

Same here, in Kenya, with an iPhone 11 Pro Max and the carrier does indeed support RCS Messaging. I’m hoping for a solution.

Europe will have to wait :( even for the “other” thing!

i had RCS messaging enabled and working fine in the early betas of iOS 18 on my iPhone 15 Pro Max, then a few later the options dissapeared on my iPhone 15 Pro Max but remained on my iPhone 13 both devices are on the same OS and have been updated with the same carrier version yet my newer iPhone RCS settings doesn't show anymore i don't remenber on which update it dissapeared but its not there anymore. both phone have carriers that support the feature fully so that's a none starter, both phones are Canadian devices and i have never had any issues appart from this with RCS on the 15 Pro Max.

Not true. It is available in Canada through all major carriers.

Do you have iCloud turned on. I read that you need iCloud turned on to use RCS. Trying to find this mysel since someone said it is mentioned someplace on Apple Documentation.
