FAQ
1. What is the primary difference between RCS and SMS?
- SMS is a basic text messaging service that works on all mobile devices and uses cellular networks without requiring internet connectivity.
- RCS (Rich Communication Services) is an upgraded messaging protocol that allows for rich media (images, videos, buttons) and interactive features, but it requires internet and works primarily on Android devices with carrier support.
2. Can RCS messages replace SMS completely?
- Not entirely. RCS relies on internet connectivity and device/carrier compatibility, so SMS remains the fallback option for universal communication, especially for non-smartphones or regions without RCS support.
3. Is RCS more expensive than SMS?
- RCS messages are typically free if you have internet access (Wi-Fi or mobile data). SMS, on the other hand, is charged based on carrier rates, which can vary depending on region and plan.
4. Does RCS work on all devices?
- No, RCS is primarily available on Android devices with compatible apps like Google Messages. Apple devices do not support RCS, as iMessage is Apple’s proprietary messaging platform.
5. Is RCS more secure than SMS?
- Yes, RCS supports end-to-end encryption in certain apps like Google Messages, ensuring secure communication. SMS is not encrypted, making it less secure for transmitting sensitive information.

10. Which is better for businesses: RCS or SMS?
