Fraud Bypass Detection / SIM Box Detection
The SIM Box Dilemma
SIM boxes have multiple negative effects
on operators, roaming hub providers and
customers alike, e.g.:
> revenue loss due to call redirection
roaming calls are intercepted, redirected
and terminated whilst being re-conducted
via the fraudulent SIM box, creating a
cost / revenue shifting along the way
> revenue loss due to service inaccessibility
SIM boxes have the negative effect that
multiple popular services, e.g. voice
mailbox, may not be available. Revenue
loss and unhappy customers is the
consequence
> revenue loss through missing callbacks
due to the redirection of calls none or
wrong CLIs will be displayed at the
recipient’s side; immediate impact is the
inability to “call back” resulting in a
significant loss of roaming revenue
> image loss through bad QoS
SIM boxes redirect calls over inadequate,
highly compressed IP connections,
resulting in poor voice quality. Call setup
time is extended which also leads to the
impression of an overall bad roaming
QoS of the home network operator.
How to get rid of it
Keynote SIGOS GlobalRoamer test platform is a world-wide distributed test system which can be used for Interconnect Fraud Bypass detection. Access to alerts and detailed trace information is possible in real time allowing blocking of SIM box numbers rapidly.
Powerful reporting techniques allow benchmarking of SIM box issues against historical values. GlobalRoamer provides the reporting capability to view reports by SIM box numbers (MSISDNs) detected list, originating networks tested, affected originating networks and actual SIM box hits over time (Hourly / Daily / Weekly / Monthly / Quarterly).
Because of the underlying service model technology it is also possible to
drill-down to the hidden detail of particular SIM box numbers affecting the
CUSTOMER network and even view detailed test trace information to provide
evidence giving proof of SIM card abuse.

Benefits:
- Reducing revenue leakage due to termination of voice traffic via SIM box equipment with active detection (direct financial impact to operators!)
- Improving quality of calls as SIM boxes tend to compromise quality leading to a reduction in customer complaints and dissatisfaction
- Advanced reports including relevant quality problems reports which will help operators to improve quality related issues
