One of the main parameters that operators’ AntiFraud use to track terminators’ SIM-card in ip gateways is the number activity in the network. It stands to reason that a man will not talk for 24 hours a day.
On the one hand, a card can be squeezed within 3-9 hours of continuous operation (maximum 19 hours by the experienced terminator). You activate and download 10 hours of the traffic, and then you get locked. Naturally, this method tremendously increases the costs and the time spent.
Even if you have constant access to the loads of SIM-cards, uploading and downloading 100 cards a day from the bank takes an incredibly long time. Let alone the top-up and activation of the bonuses (work with USSD requests), movement between gateways.
GoAntiFraud – unique voip services can cut this figure and scatter the activity of the card in completely different intervals. For example, 1 hour activity +/- 10% variation (from 54 to 66 minutes), whereupon a SIM card is automatically discharged and stands by for 3 hours +/- 30% (the scatter is 54 minutes). During this interval, the card takes a couple of incoming calls from your own SIM-card with a pre-recorded voice and dial "preferred numbers" generated by GoAntiFraud from your cards database.
All these settings are templated and can connect to any new SIM-card in one click. However, this is only one method. The coming posts will tell about calls, movement, preferred numbers, and activation of the equipment for calling from internet.
