What is SIM Boxing?

What is SIM Boxing and how does it work?

SIM Boxing is a type of telecommunications fraud that involves using a device called a SIM Box to bypass legitimate phone networks and redirect Voice over Internet Protocol (VoIP) calls through mobile networks. The SIM Box device is usually a computer server that has multiple SIM cards from different mobile operators.

When a VoIP call is made, the SIM Box intercepts the call and connects it to the mobile network through one of its SIM cards. The call then appears to the mobile network as a regular call originating from a local mobile phone number, even though it was actually made using VoIP. This enables the SIM Box operator to avoid paying the high fees charged by the legitimate telecom operators for international or long-distance calls, while still being able to provide cheaper call rates to their customers.

The process works in the following steps:

• The caller initiates a VoIP call using their internet-connected device.
• The VoIP call is intercepted by the SIM Box.
• The SIM Box routes the call through one of its SIM cards to the mobile network.
• The mobile network treats the call as a local call and connects it to the recipient's phone.
• The recipient receives the call from what appears to be a local phone number, even though it was made using VoIP.

This process allows the SIM Box operator to profit by charging their customers lower rates for international or long-distance calls than those offered by legitimate telecom operators. However, SIM Boxing is illegal in most countries, as it violates telecom regulations and causes financial losses to the legitimate telecom operators
