Hi,

When sending a message via SMPP tcp/ip bind to our SMSC anything in a message after a @ symbol is not sent.

i.e.

test@test arrives as test

This happens from both a http://127.0.0.1:8800/&PhoneNumber=....blah blah, and from the web interface.

Any advice?

Hi Spencer,

This is a very common problem. In the GSM world, the @ character is encoded as a NULL character. In the computer world, NULL is used to terminate a string of text.

By default, NowSMS uses the GSM character set for SMPP interfaces.

However, some SMPP providers expect the iso-8859-1 character set (USA/Western Europe) to be used.

To change the SMPP character set that NowSMS uses for the connection, select the connection from the "SMSC" list and press "Properties". Then press "Advanced Settings", and you will be able to change the character set. Press "OK" twice, then "Apply" to save the change.

In some rare instances, the provider may have a problem with this setting. This is because when NowSMS is configured to use the iso-8859-1 character set, it formats the SMPP packet to indicate that the iso-8859-1 character set is being used. Some SMPP servers do not understand this standard character set indication parameter. If you encounter a problem with the iso-8859-1 setting, edit SMSGW.INI, and under the [SMPP - server:port] header, look for SMSCCharset=iso-8859-1 ... on the line that follows this, insert SMSCCharsetDefault=Yes
