Is there any way to use a personal phone to make and receive calls anonymously without purchasing a new phone and calling plan? There are many capable and affordable calling apps for iOS and Android (Burner, Viber, Skype), yet all would still send and receive through my personal connection to the cellular data provider. Maybe the likelihood of investigators sending a subpoena to such companies in order to identify the 'burner' phone number of, for example, a small-time ( < $1000 ) drug reseller? Any insight is appreciated, thanks
tl;dr Is there a way to make/receive calls with (realistic) anonymity via a personal cell phone?
Not sure about phone calls, but you can receive SMS through a website (EDIT: with an anonymous phone number). Run that through VPN / tor / public wifi and you should be relatively anonymous. Google for "Receive SMS online"
