If you can afford to have a throwaway phone with a second phone line of service -- remember, WA must be tied to a phone number, and you don't want to give FB your real phone number, right? -- then you are probably doing better than the average person. Remember all those articles about how the average US resident can't afford a single $400 surprise bill? That's called privilege. Nobody is saying to "feel ashamed" about it, just remember that if you're suggesting a second phone as an acceptable solution to this problem.
