So, since the government is indeed collecting an enormous amount of data -- it definitely makes it 'harder' to stay truly anonymous -- but this is a much more anonymous solution than anything else as you are making it as difficult as possible:

- New phone numbers. - Different cell signal piggyback depending on where you're located. - 30 day cell tower location tracking / SMS storage / phone call storage -- so in the worst case scenario you've got 30 days of conversation / messages stored.

If an entity wanted to track YOU, they'd have to do voice analysis of every call in the country / region, look for specific writing patterns / keywords in your sms messages, and then try to match things up (this would be really difficult, even with lots of information to go from).

Anyhow, it's definitely not a perfect solution, but one that really helps protect privacy.
