Hello Jan,

The most likely explanation for this is that the messages contain characters that are not in the standard SMS character set. If that is the case then Diafaan SMS Server sends the message with the Unicode character set.

Unfortunately, the SMPP implementation of most wireless routers/gateways, like the Teltonika TRB140, is often limited. Sending and receiving basic SMS messages is usually OK but more advanced SMS options like long multipart messages or Unicode messages are not supported in the SMPP implementation on most devices. We have tested SMPP on another Teltonika device and found that a lot of advanced SMPP features are not supported.

If you send me the communication log of the SMPP Gateway and the configuration file of Diafaan SMS Server (menu options 'File-Export-Configuration') I can have a look to see how the messages are sent and if there is perhaps a setting in Diafaan SMS Server that would improve it. You can send the two files to email address dms@diafaan.com.

Regards, Henk

I am testing sending messages with the Teltonika TRB140 via the SMPP Gateway, when I send an SMS via the Gateways (send message) tab, the SMS is correctly delivered (Status: 200, Success: Message accepted by the SMPP gateway.) the SMS is correct on the mobile phone, but if I have configured Email Connector and I send via the connector in the log I see (Status: 200, Success: Message accepted by the SMPP gateway.) but only characters come to the sms? perhaps 10 messages containing only a question mark, what could be the cause? it looks like it has something to do with characters like @ and then eg ü etc
