Tmobile: Sidekick data plan vs Sidekick prepaid?

[bonds756]

What is the difference it looks totally the same except the Data plan you pay $0.20 per calling min. while prepaid is $0.15

Is there a difference?
per day but isnt that the same as the data plan which is a month... Basically or is it only on days you use it?!

Also why do they say $1 per day its alot easier just to say $20 a month? Why is that? Thanks

I asked the same question when i had my sidekick 2,The answer is amazing..prepaid was way cheaper.
$1.00 per day,and you get unlimited text,unlimited Internet which includes a tmail email address,yahoo chat..ect.ect.ect.
Prepaid is the way to go
