I purchase monthly 3G service when and if I need it. I hate that I have to remember to cancel service before it automatically rolls over.
I got the wifi version. When there is no wifi available I connect to the 3G network from my Droid rooted phone.
I wish AT&T would allow unlimited once again once they launch their 4G service.
I have access to enough free spots, so why pay a monthly fee, for what?I choose NOT to pay for the Monthly Service.
