Hello Yuz,

If the message is received on the mobile phone but the log in Diafaan SMS Server shows the message as failed the the most likely cause for the error is that the modem does not return a valid response after Diafaan SMS Server tried to send the message. The message is sent but Diafaan SMS Server does not know it. The error status of the GSM Modem Gateway is also an indication of problems with the modem.

These kinds of errors are usually caused by an unreliable wireless connection between the modem and the mobile network or by compatibility problems between the modem and the network.

If you send the communication log of the modem to I will have a look at it to see if there is anything wrong with the settings. Please include the serial number of your license in the email.

Regards, Henk

Hi Henk,

I have added a new GSM Modem Gateway, the problem with this is the statuscode which on the Diafaan SMS Server is '300' or simply an error but still the SMS or message was sent to the phone. By the way for the connector, I am using a SQL Connector.

I have also observed on some events like when sending or receiving a message, the Gateway changes its status from 'ready' to error state or 'Trying to connect to COM #'.

Please advise and thanks for the usual support!
