Hi,
If you want to send SMS with GSM character set in text mode,you can do like this:
excute

  1. AT+CMGF=1
  2. AT+CSCS=“GSM”
  3. But please make sure the SMS service center address is correct,You can confirm this by following this command: AT+CSCA?
    If the SMS service center address is wrong, please execute this command to modify:

  4. You can set AT+CSMP=17,71,0,0 and AT+CNMI=2,1,0,0,0.
  5. Then you can use AT+CMGS=“09843843911” to send the SMS.
