What AWS End User Messaging RCS for Business is

AWS End User Messaging RCS for Business provides carrier-verified business messaging for Apple and Android phones through API and web access. Messages can contain rich cards, carousels, images, and videos, as well as interactive replies, links, calls, calendar events, and location sharing or requests. A modal browser window can open over a conversation for workflows such as account details or payment portals. AWS says the service automatically falls back to SMS when a recipient’s device does not support RCS. Messages can be routed to Lambda, responses generated with Amazon Bedrock Agent Core, and context pulled from other AWS services. Delivery events can go to EventBridge, CloudWatch, or Data Firehose, while inbound messages can be delivered through SNS. Data is encrypted in transit and at rest within the AWS boundary; client connections require TLS 1.2, with TLS 1.3 recommended. Pricing starts at $0.01; there is no free plan. The US rich RCS and rich media plans list per-message or per-segment charges and carrier fees.
