Thats funny, I was just at their site and didn't see that.
Origionally I just added my son to our family plan, but it only had 200 text messages, ops. Over the last two years his service has grown to unlimited text and multi-media as well. His phone bill is bigger than mine and my wifes. We've made him pay for his for the last year, as his bill alone is $60/mo . Plus a phone is only good for about 9 months before he tears it up, or drops it in the commode, or gets pushed in a pool; either way, it's never his fault . Teenagers can be really reckless. So for most of the last two years he's been begging and borrowing other peoples 2nd hand phones. The funny part was he was really pushing for a I-Phone this year for Christmas. ROTFLMAO, haha.
If I could do it over, I would have gone the pre-paid route, or a phone with the GPS tracking (I really think thats a great feature that I would have loved, still would, to have on my son's phone). Once they start riding with freinds and driving, It's hard to keep up with their whereabouts.
In my experiance, there is no such thing as a $30/mo plan, after all the fees and overages.
