Not sure what that particular unit can do. Some of them have an iPhone app written that can tell you the system status.
SW 1 On or Off
etc....
I believe they all have simple code that you can text to them and they will respond back with switch status (On or off)
Check out the app "switchbox"
Two that I know of and have used with a different box are written by:

and
Cheviot Hills
PS: The cheap Chinese switch box offering is 2G cellular, so a SIM card from T-Mobile is what I use. 3G/4G boxes are likely a bit more expensive.
