For me the phone has become strictly an outgoing call machine.

A bundle of 50 minutes of incoming and outgoing calls costs 25, which works out at a flat 50p a minute.

You pay up to $1.799 (1.18) a minute for outgoing calls - or as little as $0.06 - on top of data rates, if any, and $0.015 for incoming ones.

To make an outgoing call the mobile transmits a request to the base station as requested in the control channel data stream from the base station.

Once in the target's phone, spyware lets a hacker access almost everything, including all messages, emails and incoming or outgoing calls, as well as pictures, cameras, microphones and location data.
