Quick answer. No, SMS isn’t dead — it’s being upgraded, not replaced. SMS remains the most universal messaging channel on earth, reaching virtually every phone with open rates around 98%, and it’s the guaranteed fallback beneath RCS. What’s changing is its role: rich, branded, interactive messaging is moving to RCS where it’s supported, while SMS handles universal reach and critical, plain-text messages like one-time passcodes. The realistic future is “RCS-first with SMS fallback,” where SMS quietly underpins everything rather than disappearing.
Predictions of SMS’s death miss how much infrastructure depends on it. Its universality is precisely why it survives: no app, no data connection, no device requirement. For years to come, the safest assumption is that SMS becomes the reliable base layer while RCS captures the rich, high-engagement traffic on top.
So the better question isn’t “is SMS dead” but “what belongs on SMS versus RCS” — and the answer keeps shifting toward RCS as its reach grows, without SMS ever fully going away.
Key facts
- SMS open rates are around 98%, and it reaches essentially every mobile device — its universality is why it persists.
- SMS is the automatic fallback for RCS, so it underpins RCS programs rather than competing with them.
- The trajectory is RCS-first with SMS fallback, not the disappearance of SMS.
