I use Cape every day on my iPhone. The service is excellent, and the security features haven't ever interfered with my use of the phone. They have a convenient mobile app for setting up extra features like the IMSI rotation and getting support. As a tech savvy user, it matches what I want.
I'm a target for a variety of things, and knowing that no one can SIM swap me is worth the subscription alone. The SS7 protections, encrypted voicemail, secondary numbers, IMSI rotation, etc are all a bonus.
You would be better off hosting your “phone number “at Twilio and then forwarding that number to a throwaway SIM card that nobody knows the number to.
Your “phone number “that people interact with cannot be hijacked with SS7 because it’s not a real number… you’re immune to sim swaps … And you can Jettison your physical phone and SIM card at any time with no penalty.
As a bonus, because your actual phone number is now programmable you can do interesting things like set up a SMS firewall. You can, for instance, collapse all incoming text messages to ascii-256. Or truncate their overall length. Or CC your incoming SMS to a dedicated mailbox.
I have operated like this since 2016. I have no idea what my physical SIM phone number is and neither does anybody else.
I’m a skeptic. It’s only been a handful of years since Anom was backdoored by the Feds. The surveillance data provided by cell phones is simply too good to let someone work around it
This Anom comp comes up a lot. It's super hard to prove a negative, so no matter many how times I say "Cape is not a honeypot," the critics will just respond "that is exactly what a honeypot would say."
We're working on some ideas to address this with audits etc, but it will always be tough. However, if you like the idea, and like the features, then maybe it is worth your time to do the work and get comfortable with the company. Because we're the only ones providing some of these features, and we have a lot more in the hopper still to come. I hope we can win your trust at some point.
