# 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 \$11.00 (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*.

# Requesting increases to your monthly Amazon SNS SMS spending quota
<a name="channels-sms-awssupport-spend-threshold"></a>

Amazon SNS provides spending quotas to help you manage the maximum per-month cost incurred by sending SMS using your account. The spending quota limits your risk in case of malicious attack, and prevents your upstream application from sending more messages than expected. You can configure Amazon SNS to stop publishing SMS messages when it determines that sending an SMS message will incur a cost that exceeds your spending quota for the current month. 

To ensure your operations are not impacted, we recommend requesting a spending quota high enough to support your production workloads. For more information, see [Step 1: Open an Amazon SNS SMS case](#channels-sms-awssupport-spend-threshold-open). Once you have received the quota, you can manage your risk by applying the full quota, or a smaller value, as described in [Step 2: Update your SMS settings](#channels-sms-awssupport-spend-threshold-settings). By applying a smaller value, you can control your monthly spending with the option to scale up if necessary.

**Important**  
Because Amazon SNS is a distributed system, it stops sending SMS messages within minutes if the spending quota is exceeded. During this period, if you continue to send SMS messages, you might incur costs that exceed your quota.

We set the spending quota for all new accounts at \$11.00 (USD) per month. This quota is intended to let you test the message-sending capabilities of Amazon SNS. To request an increase to the SMS spending quota for your account, open a quota increase case in the AWS Support Center.
