Application will automatically switch the mobile to Flight mode when network becomes unavailable and back when it is available again.

As an option, this application is capable of switching off MMS and 3G/EDGE function.

Helpful for those people who travels in subway or in another remote areas out of phone networks coverage and wasting all the battery charge only for network registration attempts.

Note, you should turn PIN code off on your SIM card to make application function.
