Navigate to
AI Scheduler → EventLocate the Event from which you expected SMS to be sent out and click on it

IF SMS reminders are OFF, ask Super Admin to turn them ON and follow guidelines from the inside of the app

In case you don't have necessary permissions, ask your Super Admin to troubleshoot it for you.
Navigate to
Settings → Billing Check if there is enough remaining credits in the wallet
