As a pleb, it doesn’t sound that groundbreaking to me and feels a bit deceptive. Lots of carriers now allow you to lock your sim from transfers, and many logins allow you to use an authenticator app rather than phone number. The largest benefit would be if they could maintain privacy, but from the info on their website, it doesn’t seem much better than any other carrier. Even if they don’t collect and store private data, they are no doubt using one of the big wireless carriers network which still has the ability to track every device connected to it. I could be very wrong one either of these points, if so someone please correct me, but as I see it this is just an overpriced cell service with slightly higher sim swap protection.
