Quick answer. RCS solves the trust-and-engagement gap in business texting. SMS reaches everyone but arrives as plain text from an unrecognizable number, so customers ignore it or assume it’s spam, and businesses can’t show a product, confirm a brand, or offer a one-tap action. RCS fixes this by adding verified branding, rich media, and interactive buttons to the native inbox — and it solves the reach problem too, because it falls back to SMS automatically so no message is lost.
It also solves a problem for the whole ecosystem: rising SMS spam and phishing erode trust in texting. Verified RCS senders give customers a reliable signal that a message is really from the brand it claims to be.
