# FAQs

1. **Why is the RCS deliverability low?**
   * In India, RCS is regulated, and mass marketing is limited to whitelisted templates.
   * RCS is available only on Android ecosystems, that use "Google Messages" as their SMS app.
   * Users who disable RCS on their messaging app will also not receive the RCS.
2. **What kind of RCS Client APIs can I add?**&#x20;
   * RCS Template messaging APIs are configurable on the platform.
   * JSON Payload APIs are supported via "Add RCS API".
3. **What metrics are captured in RCS reporting?**
   * &#x20;RCS reporting is similar to that of SMS reporting, with the additional event of 'Read'. So, the delivery metrics funnel is:
     * Attempted -> Sent -> Delivered -> Read -> Click (wherever available) -> Failed
