A payphone may seem like a safe solution. After all, the bad guys always used them in old movies, and there are still 305,000 working pay phones in the United States, according to the American Public Communications Council. However, because a payphone uses a landline and never moves, calls can be easily traced. Still skeptical? Reddit user Detached09 wrote, "If you don't think a payphone is traceable: Pick one up, dial 9-1-1, scream, and hang up. Wait and see how long it takes the cops to show up."
Instead, buy a disposable phone with a pre-programmed number from any convenience store or other outlet, pay cash and make calls. Using this method, you avoid associating your personal information with a cellphone carrier account. (Although the more calls you make, the easier it is to deduce your identity based on the people you call.)
