Super Pumped: The Battle for Uber Highlight

Some scammers created giant makeshift circuit boards filled with hundreds of slots to insert SIM cards, the small microchips that allow mobile phones to communicate with a cellular network. Each SIM card in the circuit board acted as a new number that could automatically respond to a verification text for a newly created account, which the scammers then used to rack up more fake rides and bonuses. After the SIMs had been used, a scam artist replaced all the SIMs on the board with a fresh set of numbers and started the process all over again. Have hundreds or even thousands of “drivers” repeat that dozens of times per day, seven days a week, and it amounted to serious Uber losses.
