### Answer

The error you're seeing ("We couldn't send the SMS") appears to be related to account registration/verification, not the SMS features within Retell AI itself. I don't have information in my sources about Retell AI's account signup process or verification SMS issues.
Here are a few suggestions:
-
Try again later – This may be a temporary issue with the verification service.
-
Check your phone number format – Ensure you're entering a valid number with the correct country code.
-
Use a different verification method – If available, try email verification instead.
If the issue persists, I recommend reaching out directly to Retell AI support for assistance with account registration.

Would you like me to try to answer generally based on my knowledge instead?
