RCS vs MMS, common questions.
How is RCS different from MMS?
MMS can attach an image but stays unbranded, low resolution, and static. RCS sends high-resolution media, carousels, and interactive buttons from a verified sender, and reports read receipts.
Should I use RCS or MMS to send images?
RCS where it is supported: the media is sharper, the sender is verified, and customers can act on buttons inside the message. SimplyRCS falls back to MMS automatically when a device does not support RCS.
Does RCS cost more than MMS?
RCS rich messages and MMS are priced similarly, and SimplyRCS passes carrier fees through at cost. Since RCS drives higher engagement, the effective cost per action is often lower.
