Change of BS on demand to the user?

Question

Mobile devices

Yesterday I heard a story about a phone that, in order to protect against position tracking by the operator, could arbitrarily change base stations - connect not to the one with the stronger signal, but to the neighboring one. And do it quite often on your own during a conversation.
Interested in the opinion of GSM experts - is this real? Will it save you from being tracked? How difficult is it to implement this on an Android phone (with the ability to change the firmware)

Answer 1

You can also manually select base stations (more precisely, frequency channels that are different on different BSs) using special applications (on previous Nokias there was NetMonitor, which on modern ones was not interested). But how will it save you from being tracked? Anyway, when communicating with any BS, the distance to it is known, the distance to all neighboring BSs is also known, and when there are many of these BSs, you can localize the subscriber quite accurately. It's about location tracking. And about tracking the conversation, so in any case it will go through the same switch - listen, I don’t want to. Perhaps all this can somehow interfere with the monsters that listen to you in the radio channel, but you still have to look for such monsters)), and they will most likely be able to track the moment of handover by signal messages.

Answer 2

I don’t see any reason to become attached to gsm, there, while we are itching for 3g, all the normal ones immediately switch to 4g, I heard something about the 5th generation, but I won’t lie, because “one grandmother said” (c)
