I still do not understand why there isn't a utility that allows you to specify which cell towers your phone will connect to.

You could download an authorized list and then deny or prompt for other towers. This would make Stingray type devices useless for spying on people who need secure communications.

In fact, it would allow foreign actors to intercept useless comms from teenagers chatting about snorting condoms while at the same time preventing important comms from being intercepted. Win-Win.
