Hello Kamesh,
Good day. Thank you for your question.
Please send the following SMS command to the device, to disable Overspeeding:
With SMS login and Password :- <SMS login><space><SMS password><space>setparam 11100:0 or "login password setparam 11100:0"
Without SMS login and Password :- <space><space>setparam 11100:0 or " setparam 11100:0"
If you are sending via GPRS then you may skip the login, password, and <space>.
Kindly try this and let me know if it helps.
Best regards.
