Boost always uses the term "month" when defining a 30 day span, if I recall correctly. Minutes and text are unlimited. The data can vary depending on the time of enrollment and whether you are using the monthly cards, or a re-boost plan which comes directly from your account. For further clarification, general support is available 4am - 8pm PST (Mon-Fri) and 4am - 7pm PST (Sat & Sun) at 1-866-402-7366.
