Hello there,
Good day. Thank you for your question.
The GPRS commands are similar to the SMS commands but you will not require any credentials, instead only the command itself. For example:
IF you would like to disable the sleep mode, then the SMS commands are as follows:
With login and password : <login><space><password><space>setparam 102:0
Without login and password : <space><space>setparam 102:0
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.
