Meucci Solutions, a company that specialises in quality measurements between telecom networks, says it has detected over 50,000 SIM boxes in use.
SIM boxes, also known as GSM gateways, are used to bypass the interconnection between networks and divert international calls to national GSM calls to evade the revenue that operators are entitled to.
Meucci says annual losses can easily amount to €3,500 per SIM box. But the use of a SIM box bypass also results in lower call quality for the end-user, and the end-user will blames this on the poor quality of the operator’s network.
