Check AT-command manual of your modem. There is probably separate AT-command for writing to a file. For example: AT+FSWRITE - SKi
@Ski thx u for your response, yes manual has below command at+fswrite=1.arm,1,512,10. nothing else,how to load from local drive is my main problem - Anto sujesh
Then you should tell little bit more about your environment. Like programming language. And also possible code-snipped what you have already tried. - SKi

I don't have any modem that supports AT+FSWRITE command. But based on SIMcom AT-command manual, AT+FSWRITE= command responds with prompt: >. Manual does not clearly tell how to use the command.

But it might work similar way than AT+CMGS= command:

  1. Send AT+FSWRITE=1.arm,0,512,10 command to modem.
  2. Wait > from the modem.
  3. Write content of the file (512 bytes) to the modem.
  4. Send Ctrl-Z char (0x1A hex) to the modem.
  5. Wait OK/ERROR from the modem.

Step 4. may not be needed, because size of the file is in the command.
