1) For work if I want to appear in a location. 2) Security if in public eifi environments. 3) Occasionally to obfuscate information if I want to download a movie or look at information, nothing interesting/nefarious but maybe you want to look at health stuff and not feel some insurance company is going to target you for ads or assume you have the condition type thing. 4) Using phone for international travel.
