Cybercriminals have begun exploiting mobile networks through a new and highly dangerous fraud technique known as the “fake mobile tower” or “fake base station” scam. Using portable equipment, fraudsters create the illusion of a legitimate telecom tower, tricking nearby mobile phones into connecting to a rogue network. Once connected, users receive fake bank alerts, OTP messages, and verification requests, leading to financial fraud.
Cybersecurity experts warn that this technique is particularly effective because mobile phones are designed to automatically connect to the strongest available signal. Fraudsters take advantage of this feature by setting up portable fake towers that overpower genuine network signals, causing unsuspecting users’ phones to switch networks without any manual action.
How a ‘fake base station’ operates
Under normal conditions, mobile phones constantly switch between multiple towers to maintain the best possible signal. Scammers exploit this mechanism by deploying portable fake towers—which can be installed in cars, backpacks, or temporary roadside locations.
As soon as a phone enters the coverage area, it latches onto the stronger fake signal. Once the connection is established, fraudsters initiate SMS blast operations, sending large volumes of messages that closely resemble legitimate communications from banks, payment platforms, or government agencies.
These messages often warn of account suspension, KYC updates, or suspicious transactions and prompt users to click links or share OTPs. The moment a user complies, scammers gain access to sensitive financial information, resulting in instant monetary loss.

Incidents reported abroad
Several cases involving fake mobile tower scams have already surfaced overseas. In one recent incident in Europe, police recovered an entire fake network setup installed inside a vehicle and arrested the suspects involved. Following such cases, cybercrime agencies worldwide have issued alerts warning of the growing misuse of this technology.
Rising risk in India
Experts believe the threat could be even more severe in India, given the country’s dense population and high dependence on mobile-based banking and digital payments. Crowded areas such as railway stations, bus terminals, markets, fairs, and public events are considered particularly vulnerable, as scammers can easily blend in and operate portable fake towers unnoticed.
In some instances, users have reported their phones suddenly switching to 2G networks, which experts say can be a red flag indicating forced connection to a rogue network. Any sudden change in network type or unexplained bank-related messages should be treated as a warning sign.
Challenge for telecom operators
Cybersecurity officials acknowledge that mobile network operators currently lack a real-time, foolproof mechanism to instantly block such fake networks. However, with cases on the rise globally, telecom companies have begun strengthening network security protocols and monitoring systems to detect abnormal signal patterns.
Experts stress that user awareness remains the strongest line of defence. They advise people to avoid clicking on suspicious links, never share OTPs or personal details over messages, and independently verify any communication claiming to be from banks or government agencies.
As cybercriminals continue to evolve their methods, authorities warn that fake mobile tower scams could become one of the most serious digital threats in the coming years unless preventive measures and public vigilance increase significantly.
