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.

"For too long, insecure networks have been the reality for both consumers and businesses, ripe for tracking, interception, and exploitation. Cape is the only carrier credibly addressing those concerns, redesigning mobile security from its core."

In The News

David Ignatius,

The Washington Post

“Cape has devised a virtual mobile network that disappears from the normal cellphone net. The phone is nearly impossible to hack or trace.”

Don’t take our word for it.

    Cape is the best and first actually privacy-focused mobile carrier i've ever encountered. Dependable enough for mobile hotspot data when I need it, and I've seen as much as I've needed, to be convinced of their importance.
