New day, new you. Rotate your mobile identity every day. Stay untraceable with Cape.

Your International Mobile Subscriber ID (IMSI) is a typically static mobile identifier that is stamped across your digital footprint, and allows carriers and third parties to profile you and persistently track your every movement.

WITH ACCESS TO YOUR IMSI:

Carriers can profile you and sell your data to third parties and ad networks, or lose it in breaches.

Governments can subpoena records associated with your IMSI, sometimes even without a warrant.

Bad actors can launch signaling attacks to track you or intercept your calls and texts.
