We are receiving a lot of international traffic in our network through SIM Box, but I am looking for the way to detect them rapidly and after delete that SIM numbers,
SIM boxes are using the IP Network till our country and after there is box with 50 SIM card that change the media and route it to our network as national traffic
Any body got any idea share it please?
We have dedicated fraud department. They are analyzing the billing data. I think they are looking for subscribers with a lot of calls and dispersed throug the whole day (24h).
The next thing is to check if the periodic location updates are in one and the same cell (no moving around the network)
I don’t know if this will help you
