Well, without any connection or GPS it’s difficult.

however, there are workarounds.

In the advanced settings, you can select the option to “Automatically enable GPS” if GPS is not already enabled in the main phone settings.

Note however that while “on-demand” GPS updates will always work if Anti-Theft was
installed rooted, there are some restrictions on non-rooted phones. On non-rooted phones
the auto-enabling only works from Android 1.6 up to Android 2.2. For Android 2.3 and later,
it is not possible to auto-enable GPS and therefore it is not possible to use the SMS
Command to obtain GPS Updates.

you can also force the data connection to become active and stay open:

Force data connection on By enabling this option, you can force the phone’s data connection to remain open thus ensuring it remains reachable via the internet for as long as possible.
however, this will only become active if: - the thief changes the SIM card - or you send a SMS to the phone marking it as "LOST" (the sms command is " lost")
