[help] How can I use IoT devices ?

Hello everyone, hope you’re having a nice day.

I need some help on using an IoT lock The lock has SIM card and GPS in it.

And I need to send commands to it and take some data from it inside my Nodejs server.

I have no experience with IoT and all I have is a pdf containing commands and what they do. Commands like H3, L4, A1 …. etc

But I don’t know how to connect to it ? and how to send commands ? and receive data ?

Any information would be helpful.

Thanks a lot
