But for mobile phone calls, location (Cell ID) is on that list...

So, can we be sure that because location is NOT on that list for other
types of communication, it is not collected or available for them?

So, if you are not being individually targetted, you can avoid having
your location recorded by avoiding using voice calls (use texts and/or
VoIP instead)?
