Hi Carlos Leyva,
SMS sending via ACS may not work due to a few reasons. The phone number used might not support SMS,
or it could be restricted
by region. Configuration
issues, such as incorrect settings or permissions in Azure, can also cause problems. Additionally, if you're in trial mode or haven't set up billing, SMS might be limited.
- Please check SMS Enablement by going to Azure Portal -> Communication Services -> Phone Numbers -> Select your purchased number -> Ensure
SMS
is listed underCapabilities
to confirm SMS support. - Verify Phone Number Status by going to Azure Portal → Communication Services → Phone Numbers → Ensure your number is
Active
and, if toll-free, has completed toll-free verification to avoid SMS blocking in US and CA. - Ensure your phone number supports SMS in the region or country you're sending messages to, as functionality may vary.
- Check
Service Health
by going to the Azure Service Health portal to see if there are any issues affecting Azure Communication Services. - To test with Azure CLI, try sending a test message through Azure CLI to bypass any potential UI issues.
az communication sms send --resource-group <your-resource-group> --communication-services-name <your-service-name> --from <your-phone-number> --to <recipient-number> --message "Test message"
