Rich Communication Services

Rich Communication Services (RCS) is a communication protocol between mobile-telephone carriers as well as between phone and carrier. This aims to replace SMS messages with a richer text-message system, provide phonebook polling (for service discovery), and transmit in-call multimedia.


How Bandwidth is Involved with RCS

Bandwidth differs from other companies in that they do not rely on RCS to allow their customers to easily incorporate voice calling and mobile messaging into their applications. Instead, Bandwidth offers voice applications programming interfaces (APIs) through a cloud platform for OTT providers to add in those voice and messaging capabilities.


What Are the Benefits of Bandwidth’s Alternatives to RCS

Bandwidth offers a cloud-based platform that can support its customers’ applications on a large scale. The establishment of this platform in lieu of using RCS is that Bandwidth is able to incorporate a multitude of our services for our customers through our API. In addition to incorporating voice and messaging into applications, Bandwidth also offers the ability to obtain phone numbers, number porting, and 9-1-1 access.
