# Requesting support for Amazon SNS SMS messaging
<a name="channels-sms-awssupport"></a>

**Important**  
The Amazon SNS SMS Developer Guide has been updated. Amazon SNS has integrated with [AWS End User Messaging SMS](https://docs.aws.amazon.com/sms-voice/latest/userguide/what-is-service.html) for the delivery of SMS messages. This guide contains the latest information on how to create, configure, and manage your Amazon SNS SMS messages.

Certain SMS options with Amazon SNS aren't available for your AWS account until you contact Support. Create a case in the [AWS Support Center](https://console.aws.amazon.com/support/home#/) to request any of the following:
+ An increase to your monthly SMS spending threshold

  By default, the monthly spending threshold is $1.00 (USD). Your spending threshold determines the volume of messages that you can send with Amazon SNS. You can request a spending threshold that meets the expected monthly message volume for your SMS use case.
+ A move from the [SMS sandbox](sns-sms-sandbox.md) so that you can send SMS messages without restrictions. For more information, see [Moving out of the Amazon SNS SMS sandbox](sns-sms-sandbox-moving-to-production.md).
+ A dedicated [origination number](https://docs.aws.amazon.com/sms-voice/latest/userguide/phone-numbers.html)
+ A dedicated [sender ID](https://docs.aws.amazon.com/sms-voice/latest/userguide/sender-id.html). A sender ID is a custom ID that is shown as the sender on the recipient's device. For example, you can use your business brand to make the message source easier to recognize. Support for sender IDs varies by country or region. For more information, see [Supported countries and regions for SMS messaging with AWS End User Messaging SMS](https://docs.aws.amazon.com/sms-voice/latest/userguide/phone-numbers-sms-by-country.html) in the *AWS End User Messaging SMS User Guide*.

When you create your case in the Support Center, be sure to include all the required information for the type of request that you're submitting. Otherwise, Support must contact you to obtain this information before proceeding. By submitting a detailed case, you help ensure that your case is fulfilled without delays. For the required details for specific types of SMS requests, see the following topics.

 For more information on sender IDs, see the following documentation in the *AWS End User Messaging SMS User Guide*:
