Is RCS Replacing SMS? What's Driving the Shift
iPhone support, verified senders and richer experiences are pushing business messaging from SMS to RCS. What's changing — and how to prepare.
For decades SMS was the only messaging channel that reached every phone. That's changing. RCS is becoming the default experience in the built-in messaging apps on both Android and iPhone — and businesses are following.
What's driving the shift
- Platform support: Google Messages has supported RCS for years, and Apple added RCS to iPhone with iOS 18.
- Trust: verified sender branding helps customers tell real messages from SMS phishing.
- Expectations: customers are used to images, buttons and read receipts from chat apps.
- Measurability: read receipts and button clicks give marketers far better data than SMS.
SMS isn't disappearing
SMS remains the universal fallback. Phones without RCS, users who have turned it off and markets where business RCS isn't launched yet all still rely on SMS. For the foreseeable future, the two will coexist — with RCS as the preferred experience and SMS as the safety net.
What it means in Europe
Adoption of RCS business messaging differs by country and carrier. Brands that start now — with transactional use cases and SMS fallback — build experience and approvals while the audience grows, rather than scrambling later.
How to prepare
- Audit your current SMS traffic: which messages would benefit most from rich content?
- Prepare brand assets and start agent verification early.
- Choose a platform that supports RCS, SMS fallback and other channels in one place.
- Redesign one high-volume message as a rich card and compare results against SMS.
RCS doesn't replace SMS overnight. It upgrades it — one capable phone at a time.
