We are in world where we need to spread our words and stories to as many people as we can. Since, everybody gets most of their information through mobile phones in this digital era, it has become a new haven for business to reach the people. Now, a business can utilize Amazon SNS to send SMS messages to the SMS-enabled devices on a very large scale and reach as many eyes as one would want. You can publish messages directly to the phone numbers for these devices.

Not only can you reach out to practically unlimited length, you can do so while having a total control on whether the message is optimized for cost or reliable delivery.

If we look into the workings of the service, each SMS message can contain up to 140 bytes, and the character limit depends on the encoding scheme. For example, an SMS message can contain:

  • 160 GSM characters
  • 140 ASCII characters
  • 70 UCS-2 characters

If you publish a message that exceeds the size limit, Amazon SNS sends it as multiple messages, each fitting within the size limit. Messages are not cut off in the middle of a word but on whole-word boundaries. The total size limit for a single SMS publish action is 1600 bytes.
