Hello Nicalaus,
Good day. Thank you for your question.
If you would like to check the current parameter settings without changing them then you may send the getparam command to the device via SMS/GPRS.
For example, if you would like to receive the information on the sleep mode, then kindly send the following command:
With login and password : <login><space><password><space>getparam 102
Without login and password : <space><space>getparam 102
where 102 is the ID value of sleep mode. If you are sending via GPRS then you may skip the login, password, and <space>.

Please try this and let me know if it helps.
Kind regards,.
