A product-team playbook for testing SMS onboarding copy, retry states, number formatting, and region-specific verification behavior.

What to test

• Number format validation
• First code and resend code paths
• Blocked, delayed, and malformed OTP states
• Support messaging when the user cannot receive a code

Evidence standards

• Use exact timestamps
• Record country and app environment
• Capture the user-facing error message
• Separate QA numbers from employee personal devices
