    Hi all,

    I am trying to send a SMS with a Samba 75 Modem but every time that I try I get this error. Anyone know how can I fix this?

    Based on posting on another forum, it looks like the reason for this is that the “SMS Service Center Address” is incorrect.

    To set the SMS service center address, use the AT+CSCA command. Check with your service provider what that address should be.
