I thought I would post some info that some here are apparently not aware of... that being LE routinely monitoring cell phone numbers in a particular area.
There are various ways/methods but in essence they all work like the STINGRAY technology.

Without getting too technical this bit of Tech plays the part of a telecom and sniffs up cell phone connect info. That is... it captures cell phone numbers located within it's reception area. Since this is "meta data" that is data about a personal communication not the content of the call or communication itself... courts have decided that it is legal for broad collections by LE to capture cell numbers.
Obviously this is to further enforcement of higher level crimes like drug/gun trafficking. BUT this data is no doubt captured over a significant time and numbers that show up again and again and again... might get unwanted attention. Especially if this number can be correlated with other data of less than legal activities... such as say backpage.
In general you are playing a) the frequency of your number showing up at say 635 and 75 and you don't work for TI... b) or how easily your number can be "correlated" with a number frequently at 635 and 75
Tactics a person who wants privacy might try:
- A person might try to mask their number with a zero in it by using an oh "O" char
- A person using "Alt codes" found at http://symbolcodes.tlt.psu.edu/accen...ealt.html#math to mask numbers Ex: ‰ try before ten digit and after
- A person might put: nine seven two 555-5555 in a personal
- A private type might keep the cell phone on at a bare minimum during meetings, yes turning off is fine (except iphones)
- A person might NOT use an iphone... (another story)
- A person might use a hobby phone specifically for meet ups
- A person of course would turn off ALL gps location services and not use an iphone
- A person might NEVER EVER use gps navigation to locations... try magellan gps you can get from electronics store (separate from PHONE!)
Thats all I have now... If there is interest I can post more ideas for your privacy.
