Absolut hoax/urban legend. Charging of mobile calls is done in the operator sites not in mobiles. If you have prepaid subscription then the charging is done on-line (during the call) by IN (Intelligent Network device) that is in case of Zain Kuwait Siemens Charge@Once platform. When you establish the call, the call is triggered from mobile switching center (MSC) to IN. IN receives IDP(Initial Detection Point) message. Based on the time, called number and location of callling party, the tariff for the call is defined. Charging starts as soon as called party answers the call based on the defined tariff. Time of the answer is detected as well as end of the call (Call Disconnect). The account that is deducted resides inside the IN system, not in the mobile. No way to fool the system with any tricks in mobile. If you have postpaid line, the sequence is a bit different. For postpaid calls, the tariff is defined according to same criterias than for prepaid calls. This time MSC takes care of the detection of answer and call disconnect times. For each call a Call Detail Record (CDR) is generated in the MSC including start time, end time, call duration, tariff etc. Based on that data post processing system 'writes'a row into your bill. Any tricks related to clock chips in SIM or phonedoes not have anyimpact since time used for defining start/end times is located in network element (IN/MSC) that handles the call. Well… Absolut hoax/urban legend.

Regardless of how big a telecom is, as long as they are using GSM technology - assuming that the basic architecture remains static - telecom subscribers are at risk.

Making phone calls for free is impossible because Zain calculates the time from there side not from the phone side.

I just tried covering up the clock section of the chip and make a phone call but my phone wouldn't even connect to the network! if there is a hack its not by covering up a section of the chip.

Fring is also blocked since it allows us to use IM and skype on our mobile phones through wifi. i'm in the uk since last year and i've been going through hell when trying to call home (whether landline or mobile). I've been heard and i think a blogger wrote about it here (?) that this problem is because the ministry is using internet connection for international phonecalls! well, most of my text messages are not going through to Zain, and whenever I want to call anyone in Kuwait i must spend 20 minutes redialing.
