Don’t worry, I will try to help you solving this issue.
Could you please show the complete code of temp_sms.py and conf.py as well for better understanding?

Hi @mshakti.shukla,

Check your DEVICE_ID variable in your conf file. Your device id is incorrect.

Do let me know in case you need any other information.
