I recently updated my phone to iOS 18 and the RCS messaging feature was working nicely with others that don’t have an iPhone. I noticed whenever I leave my house or disconnect from WiFi, it disconnects me from RCS messaging and uses SMS. I checked with my carrier and it allows for RCS messages.

Check to see if you have a Carrier Update available. Your carrier can support RCS, but it will not be available to you until they issue the Carrier Update on your phone to use the feature on their network. You can also use this link to see the version number of the Carrier software you have to confirm with Xfinity that it is the latest version.
Manually update your carrier settings on your iPhone or iPad - Apple Support
You can also try to Reset Network Settings on your phone. Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. This will also reset your WiFi passwords, so you would need to enter them again the first time you login to your WiFi network.

The carrier has to specifically support RCS for iPhone. They will do this through a Carrier Update on your phone. Many carriers have not adopted RCS on iPhone. Your carrier may have RCS, but they have not implemented the steps needed to issue the Carrier Update on your phone.

Here is a list by region of the carriers that have supported RCS on iPhone.
Wireless carrier support and features for iPhone in the United States and Canada - Apple Support
I guess you should put a call into your carrier and see if they can rectify the situation
RCS is only suppose to work on the cellular network on a iPhone. On a Mac it can use wifi. You also have to be logged into iCloud on the device.
I am using it on my iPhone. And I am logged into iCloud in my iPhone. It only works on WiFi.

RCS messaging only works on WiFi
