# "Cell-site simulators (CSS)—also known as #IMSI Catchers and #Stingrays—are a tool that #lawenforcement and governments use to track the location of phones, intercept or disrupt communications, spy on foreign governments, or **even install malware** . CSS can also be used to send spam and engage in fraud. A common tactic with CSS is to trick your phone into connecting to a fake 2G cell tower. To prevent your phone from automatically connecting to a CSS, you can **disable 2G** on your phone."

The only way to ensure this does not happen is to **turn the phone off completely**."
