Hold on. Cell towers still know where the device is. If a group of people in an area have stable ismi’s and one person’s ismi is rotating daily, it doesn’t take a genius to figure out who’s now using cape. Using it for travel makes sense, but again being a device that doesn’t a have an owner is, as the kids say, sus.

It depends what your threat model is. Most telco data collection and resale is based on IMSI’s attached to KYC’d customers. If they can’t get personal information and the IMSI looks like it’s a day old, that data is inherently less valuable to data brokers. The large telcos have plenty of clean data with stable IMSI’s tied to KYC’d customers that is worth more.
