The landscape of mobile messaging seems to undergo a massive shift with the entry of RCS into the iOS domain. Although, Apple took time to embrace the rich communication services, its eventual support to protocol marks an over pivotal moment.
But why was there a delay? Maybe Apple wanted exclusivity to rich messaging features with it’s iMessage after all, 56% of the U.S. market is currently using iOS but then the demand for cross-platform communication grew too loud to ignore.

And the chat-bot performed the task without the assistance of any technical expertise. The entire exercise resulted in a cost-saving of $11 billion.
According to Business Messaging Consumer Survey, 2024 WhatsApp is first in 10 of the 15 markets, with Facebook Messenger in 3 (USA, Canada and France). The same report suggests, China has the highest penetration of rich messaging usage, that is, 66% where WeChat is by far the most used channel, followed by:

Takeaway: A Budget-Friendly Messaging solution for Enabled Regions
When it comes to picking between WhatsApp and RCS for your business, it really boils down to what matters most to you in a messaging platform. For instance, if you’re looking to upgrade your SMS communications and are okay with its regional limitations, RCS could be a fantastic option with its cool features like:
- Sharing high-quality media
- Interactive elements
Carrier support, regulatory issues, and platform adoption are some of the geographic constraints that can affect the accessibility and functionality of RCS. USA, Japan, and parts of Europe are regions with active RCS network, hence these countries can have better functionality.
Therefore, choosing the right platform for business, distills down to two parameters:

A combined approach utilizing both RCS and WhatsApp could be an excellent way to go forward. RCS provides impressive features and cost-effective options for fostering meaningful customer connections, while WhatsApp's extensive user base enhances the ability to reach a wider audience effectively.
