RCS wins on experience, branding, and measurability. SMS wins on universal reach and simplicity, it works on every device with no data connection. That’s why a strong program is RCS-first with SMS fallback rather than one or the other.
RCS vs SMS, common questions.
What is the difference between RCS and SMS?
SMS is plain text, capped near 160 characters, with no branding or interactivity. RCS adds a verified sender name and logo, images and carousels, tappable buttons, read receipts, and much longer messages, all in the same inbox.
Does RCS replace SMS?
It upgrades it. On phones that support RCS the customer sees the rich, branded version. On phones that do not, SimplyRCS sends SMS automatically, so every recipient gets the best experience their device allows.
Is RCS more expensive than SMS?
RCS is priced per message like SMS, and SimplyRCS publishes both rates. Because branded, interactive messages drive higher engagement, the return per message sent is usually better.
