I would recommend you to read this post in our Wiki about setting up GPRS settings on FMB001 device: https://wiki.teltonika.lt/view/FMB001_GPRS_settings
Normally, when setting up a server you should configure APN, APN username/password, server domain, server port fields.
APN is your GSM operator's access point name.
APN username and password - your GSM operator's APN username and password if there are any.
Domain - this is a field where you enter your specific server's IP where all of your records will be sent to.
Port - your specific server's port
If you do not have your server ready (which I assume you don't), you can take a look at our TAVL platform: https://wiki.teltonika.lt/view/Teltonika_TAVL
Or other supported platforms: https://wiki.teltonika.lt/view/Fleet_Management_platforms
