RCS vs WhatsApp for Business Messaging
Short answer: WhatsApp reaches people inside an app they already use for chatting, and supports two-way conversations and rich flows. RCS shows a verified sender in the phone's default messaging app, with no app install, but only on devices and operators that support it. Most businesses do not choose one: they use WhatsApp for conversations, RCS for rich branded alerts and SMS as the fallback.
The right mix depends on your audience, message type and budget. Use the comparison below, then see the omnichannel platform for combining channels with fallback.

How to decide for your audience
Check what share of your contacts have WhatsApp and which phones they use. Start with the channel most of them reach, run a small test on the second, and compare delivery and read data in your reports.

RCS vs WhatsApp questions
Is RCS a replacement for WhatsApp?
No. They overlap for business messaging, but they reach different audiences and work on different rules. Many businesses use both.
Which is cheaper, RCS or WhatsApp?
It depends on message type and current rates set by operators and Meta. Compare current rate cards for your use case.
Does RCS work on iPhone?
Apple added RCS support to Messages from iOS 18. Business RCS depends on the operator, so check availability.
Can I use both in one campaign?
Yes. Choose a first channel and a fallback so the message arrives on the next channel if the first fails.
Do I need to verify my business for both?
Yes. RCS uses brand verification and WhatsApp uses business verification with Meta.
