More details here on all three methods to send messages to phones using SNS here: http://docs.aws.amazon.com/sns/latest/dg/SNSMobilePush.html
Here are some things to be aware of:
· AWS Region: Mobile push to Android, iOS and Kindle Fire devices works in all public AWS regions, but SMS is only available in US-East
· Recipient location: Mobile push recipients can be anywhere in the world so long as they have IP connectivity. But SNS currently only supports US numbers.
· Topic versus Direct mobile push: Mobile push notifications can be directly addressed to a single endpoint, but SMS currently must be delivered through a topic.
