That's what they say, but it's not true. Now, you may have to sign up for the $60 plan initially, but after the first month, you can always call and switch to the $50 plan. Funny thing is, if you get a 4g phone, you actually have the option to go down to the $40 plan, which only includes 100mb of video streaming.
You really cant beat the $40 a month plan for 4g if you don't plan on streaming any videos. Most prepaid carries are more than that without the 4g.
Ive also found that though I initially thought Youtube counted against my data, I don't think it does. HBOGO seems to be the only thing I've been able to find that actually does count against the usage. Have been using Iheart radio, Pandora, ect. for a while now and my meter never moves.
I even heard that you can still wifi teether and it won't count against the usage, not that I would do such a thing.
