Requesting increases to your monthly SMS spending quota for Amazon SNS

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. 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. By applying a smaller value, you can control your monthly spending with the option to scale up if necessary.


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 $1.00 (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 Amazon Support Center.

Step 2: Update your SMS settings on the Amazon SNS console

After we notify you that your monthly spending quota has been increased, you have to adjust the spending quota for your account on the Amazon SNS console.


Important: If you skip this step, your SMS spend limit won't increase.

  3. On the Mobile text messaging (SMS) page, next to Text messaging preferences, choose Edit.

    You might receive a warning that the entered value is larger than the default spend limit. You can ignore this.

  5. Choose Save changes.


    If you get an "Invalid Parameter" error, check the contact from Amazon Support and confirm that you entered the correct new SMS spend limit. If you still experience a problem, open a case in the Amazon Support Center.
