GSM Band: 850/900/1800/1900Mhz. Reset the phone: Send number 444 to alarm phone. Reboot the phone: Send number 999 to alarm phone, start success after 1 minute. Expansion Card: Mini TF card. Sound monitoring: Send number 666 to alarm phone.
I'm sure it has been asked before (Probably by me if I know myself correctly) But why not use one of these? It puts location right on Google Maps for you.
Drawbacks I see are
1. Needs a sim card (but cheap ones cost $60/year)
2. Must have cellular coverage at location
What am I missing?
