Blocking SMS Sending: Reasons

12.06.2026

When the platform cannot deliver a message, it moves it to Blocked SMS instead of sending it. Each blocked message includes an error code and a description that explains why it was stopped. Reviewing this page is the fastest way to diagnose routing, pricing, or configuration issues.

Blocked SMS Page

Go to Current traffic → Blocked SMS.

Blocked messages are never charged. The client's balance is not affected.

Each row shows the Client, Sender, Phone, Text SMS, Time, Error code, and Detail description. Use the filters at the top – Client, Sender, date range, Phone, Destination, Manager, Error, Limit – to find specific messages.

Click the eye icon in any row to open the full detail view for that message.

The detail page shows the Phone, Client, Sender, Country, Text SMS, Type, Type Send, Time, Error, and Error description for that specific message.
