  1. Off topic but I have an issue when trying to send SMS message using SIM900 module.
    I’m using the firmware version: 1137B03SIM900M64_ST_ENHACE
    Here is my problem:

    AT+CMGF=1\r
    
    OK
    
    AT+CSCS="GSM"
    
    OK
    
    AT+CMGS="+xxxxxxxxxxx"
    
    > my_message_here_which_is_more_than_70_characters
    
    +CME ERROR: 765
    
    

    Can you give me some help over this?
    Thank you.

      1. Hi, my message contains only alphabetic characters, from ‘a’ to ‘z’ and ‘A’ to ‘Z’ only. I tried the same message with another module (different firmware version) and successfully get this done. What should I do now ? Thank you.

          1. I’m sorry, the other module’s firmware version is the same (1137B03SIM900M64_ST_ENHACE).
            Is there any setting for SMS sending function ?

          2. “May be you are sending in Text format while AT+CMGF is not set for text!”
            So which command is for setting text mode ? I’ve stuck at this for nearly 3 days.

          3. Thank you, but they shown the same way as I did before. Is there any command to reset the SMS function back to factory setting.

          4. You may use AT&F command. It will load default settings for the modem (including ones not related to SMS as well)

          5. after issuing the AT&F command, it works now, it’s might because some of my setting was affected this function, I’m gonna double check them right now. thank you for your kindfully help.
