Amazon Pinpoint is an AWS service that you can use to engage with your customers across multiple messaging channels. You can use Amazon Pinpoint to send SMS text messages and voice messages, in addition to push notifications and email. The Amazon Pinpoint SMS and Voice API provides programmatic access to options that are unique to the SMS and voice channels and supplement the resources provided by the Amazon Pinpoint API.

Regional Availability
The Amazon Pinpoint SMS and Voice API is available in several AWS Regions and it provides an endpoint for each of these Regions. For a list of all the Regions and endpoints where the API is currently available, see AWS Service Endpoints in the Amazon Web Services General Reference. To learn more about AWS Regions, see Managing AWS Regions in the Amazon Web Services General Reference.
In each Region, AWS maintains multiple Availability Zones. These Availability Zones are
physically isolated from each other, but are united by private, low-latency, high-throughput, and
highly redundant network connections. These Availability Zones enable us to provide very high
levels of availability and redundancy, while also minimizing latency. To learn more about the
number of Availability Zones that are available in each Region, see AWS Global Infrastructure
