The $5.99 T-Mobile plan is /not/ full internet access. It's usually limited to /just/ T-Mobile pages, however, T-Mo has, for whatever reason, turned the restrictions off, for now. They could turn them back on at any moment. If you're not under contract right now, looking at the Sprint SERO plan (Google it for information on how to get it). $30/month + tax gets me 500 anytime minutes, unlimited N&W, unlimited texts, and, here's the kicker, unlimited data.
