GSM 07.05

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 , pg. 25) before en-
tering the text/pdu. Use of the line termination character followed by the
response formating character (see +ATS4, default , pg. 25) 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.
