You could short out the antenna but that could burn out the transmitter and things around it.

You could change the software on the phone and remove the code to start up the cell transceiver.

If you remove the sim card then the phone will not login to any carriers network and will not contact the internet.
The phone will still be able to make emergency calls and arguably you could be tracked via the IMEI and possible GPS feedback that is supposedly part of the emergency call service.
In theory the carriers could let non sim enabled phones to login to their networks and then mask them out but there would be little value to this so I doubt that they would carry on some truly surreptitious tracking just for the joy of it.

with the advent of strong encryption it is in the best interests of multinationals
and governments (+1% and Capital) that there are other ways of obtaining data.

it would be trivial for the same players to make every person in the world 100% secure
and private, if that was the objective.

As I don't want to be one of the 'chickens' I am wanting a way of shutting down 
a black box internal cell phone wireless transmitter. I need to use the black box, 
would very much rather not but for health reasons its quite useful, but don't want 
the stupid thing to be transmitting. According to the 'idiots' selling the thing it will 
only transmit AFTER its been logged onto the companies 'cloud' (like I'm going to 
pay for insecurity!!). There seems to be no understanding that 
1. I don't want their access to my data
2. I don't want the machine looking for a cell network.

Somehow the sellers (and manufacturer) are missing the point that if the 
machine can send cell phone signals it can also receive them - - - and I won't 
allow that if I can help it. The machine has what is termed an 'airplane' mode but 
use of this results in regular requests to be taken off of that mode. ET is desperate 
to call home.

How could I disable this 'feature'?
