Note
• Use CTRL-Z at the end of input to send the message and return OK.
• Use ESC at the end of message input to abort message send operation.
NO message is sent although display returns OK!
• Sending e-mails via SMS: Note that some providers do not recognise @
symbol. Possible alternative “!” for “@”
• After invoking of the command CMGW, CMGS, CMGC it is necessary to
wait for the ">" symbol and only afterwards the text can be sent to the
module
• At baudrates lower than 19200 it is recommended to use the line termi-
nation character only (refer to +ATS3, default <CR>, pg. 26) before en-
tering the text/pdu. Use of the line termination character followed by the
response formating character (see +ATS4, default <LF>, pg. 26) can
cause problems.
• All characters entered behind the “>” symbol will be recognized as GSM
characters. For example, “Backspace” (ASCII character 8) does not de-
lete a character, but will be inserted into the SMS as an additional physi-
cal character. As a result, the character you wanted to delete still ap-
pears in the text, plus the GSM code equivalent of the Backspace key.
