I did mine online also, but it is the same plan.
I have the $30 a month plan thinking that if I used more than 1000 minutes a month I would bump it up to the unlimited plan.
Well, wonder of wonders, the unused minutes roll over! I have had the phone since March and I still have 42 hours on my account.
I have only had 1 issue, a message sent did not get to me until a couple of days later when another message was sent. Other than that, it is a great plan.
