ESME_RPROHIBITED in SMPP

What is ESME_RPROHIBITED?

ESME_RPROHIBITED (Error Code: 0x00000105) indicates that the requested operation is prohibited for the ESME. This means the SMSC has explicitly restricted the ESME from performing the action.

Possible Causes

The ESME account lacks permission to send messages to the specified destination.
Content filtering rules block the message.
Geographical or network restrictions prevent message delivery.
The SMSC has blacklisted the sender or receiver.
Regulatory compliance issues.

When Does It Happen?

This error occurs when the SMSC enforces a policy that prevents the ESME from submitting a message, binding, or performing another SMPP operation.

How to Solve It?

Verify if your account has the necessary permissions to send messages to the destination.
Check for regulatory restrictions or content filtering rules.
Ensure that the destination number is not blacklisted by the SMSC.
Contact your SMSC provider to understand the restriction and request access if necessary.

This error typically requires coordination with the SMSC provider to determine the specific policy restriction in place.
