@jihadjimmy >The main issue I see is that manufacturers and carriers will demand you activate that eSIM at all to be able to use the phone even when you don't want mobile service
Sure, although I can think of only 4 usages of a mobile without mobile services.

>Right now you can still just get a shitphone, never put a SIM card and never get tracked by some carrier 24/7, and then mitigate other potential tracking schemes that can be used against users.
I'm pretty sure that mobile chipsets are always connected to a mobile tower if one's in range even without a SIM card and "no signal" being displayed, due to emergency service requirements (if I remember correctly, it might be a legal requirement in the USA for a 911 call to go through even without a SIM card).

Sure you can turn aeroplane mode, but that's really just asking nicely for the mobile chipset to stop transmitting.

The only way to be sure with tracking devices is to tear out the mobile chipset, GPS, Wi-Fi, Bluetooth and any NFC antenna's sadly (you may need to solder in a resistor to simulate an antenna as well, as I have no doubt that some tracking devices are designed to stop working if it's detected that the antenna is missing).

>with mandatory eSIM it's impossible to get and use a shitphone anonymously
With or without a eSIM, it's impossible to use a tracking device anonymously unless you have it sealed in a Faraday bag, except you can't use it then.
