+CMS ERROR: 304
I can send the SMS with text mode successfully. Could you please advise ?
Thanks.

Problem solved after using a Linux-based terminal. It seems Putty added another character before the ‘ctrl-z’ character when I press Ctrl-Z, causing the modem to return error.

Hi,
I’m using ‘minicom’ in Linux to get this working.

I have the same problem
Your Ctrl-Z character needs to be on the same line as the PDU. There must be no new-line character between them.

Alternately, you can use ‘TeraTerm’
