Use cases detected by Argyle Data’s network usage fraud apps:

Call Collision

Multiple subscribers roaming in a country neighboring the home country make many long, overlapping calls to the same group of premium rate numbers in a risky foreign country.

International Revenue Share Fraud (IRSF)

A subscriber roaming in a country neighboring the home country makes multiple long calls to a premium rate number in a risky foreign country.

Inactive Customer

A customer whose account has been deactivated is still using the network.


A non-subscriber in a foreign country makes a large number of calls to different subscribers and hangs up immediately.

IMEI Switch

A subscriber roaming in a foreign country first displays normal usage patterns.  The IMEI associated with the subscriber’s SIM card then changes, after which there is high call activity to premium rate numbers in a risky foreign country.

High Voice Usage

A customer with an individual plan (i.e. a non-corporate account) uses an unusually high amount of voice minutes when roaming.
