Troubleshooting

SMS codes don't arrive.

• In Mobile code delivery, check the route is Ready. If it says DLT template id missing or No approved one-time-code template, fix that on the SMS channel page.
• For +91 numbers, the sender and template must be DLT-registered.
• Check the number's country is in Countries that can receive codes.
• If the provider sends delivery reports, copy the webhook URL shown on the card into the provider's settings so stuck messages fail over to the next route.

Email codes don't arrive. Ask the customer to check spam. Check Settings → Email Logs to see whether it was sent.

"Too many requests". The customer hit Max sends per window or the per-phone limit. They must wait, or you can raise the limit.

Customers aren't offered SMS. No phone route is ready, or SMS isn't in Allowed channels for that flow.

Registration fails with "verification required". Verify at signup asks for a code the customer didn't complete. If you require phone, make sure SMS works.

Checkout is stuck on verification. Turn off Require verification before checkout while you fix delivery problems, so sales are not blocked.
