How to know if the RCS chats have been sent?

RCS chats is a feature that allows you to send images, videos, and audio messages in high-quality, far beyond the limitations of standard SMS. This creates a richer, more interactive messaging experience. RCS shows when your message has been delivered, read, and when the recipient is typing a response. This makes conversations more engaging and gives you better context.

1. Timer icon shows your message is being sent;
2. Single check icon shows your message has been sent;
3. Double check icon shows your message has been delivered;
4. Color-filled double check icon shows your message has been read.
