Cannot create new Pinpoint acct to update spend limit? How do I do that now?

You're right that Amazon Pinpoint is being discontinued, with support ending on October 30, 2026. However, the SMS and voice messaging capabilities have been moved to AWS End User Messaging SMS, which is the service you should now use instead of Pinpoint for these functions.

To set or update your SMS spending limit, you have two options:

1. Use the AWS End User Messaging SMS console directly (not Pinpoint)
2. Use the AWS CLI with the pinpoint-sms-voice-v2 commands

For example, to increase your enforced limit for the SMS channel using the AWS CLI, you can run:

aws pinpoint-sms-voice-v2 set-text-message-spend-limit-override --monthly-limit NewEnforcedLimit

Replace "NewEnforcedLimit" with a value between $1 and your account limit.

If you need to request an increase to your account limit (not just set an enforced limit), you'll need to create an AWS Support case:

1. Sign in to the AWS Management Console
2. Create a new AWS Support case
3. Choose "Looking for service limit increases?"
4. Under "Service quota increase", for "Service", choose "Pinpoint SMS" for SMS spending limits or sending rates
5. Complete the required information and submit your request

The AWS Support team will review your request and respond within 24 hours.

In summary, you don't need to create a Pinpoint account - you should use AWS End User Messaging SMS directly, and if needed, open a support case specifically for SMS quota increases.
