Here's the AT&T link to their pricing:

Just be certain to set up a reminder for yourself to cancel the plan a few days before the 30 days is up. That won't affect your use of the remainder of any data, but it will protect you from AT&T automatically renewing the monthly plan.
This link is old. Don't they have 3gb for $30? Also, isn't it the same for 4gLTE?
The guy at att said that if I cancel my monthly plan I would have to pay the $36 activation fee again when I signed it up again. Does that sound right?
