When i send command "LOCATE" over SMS, smartphone stealth recieve sms, turnOn Wifi (all wifi routers turn off around), turnOn GPS, but not not turn on GPRS.
Why?!
If my phone not in wifi area, what is the most likely, how i can locate my phone?
For example, app "real time GPS tracker" turn GPRS on by SMS message, and this right.
May be I am missed something?
