Abstract: Method, system, and device embodiments including a wireless device having a processor, a memory in communication with the processor, and a transceiver are provided. The transceiver is in communication with the processor and is operable to transmit and receive information via a wireless connection. The device is operable to provide a wireless connection based upon a plan having a predetermined number of available units. The plan usage is tracked by a provider through use of a calculation method utilizing unit calculations that are not equal to exact time usage to decrement available units. The device is operable to emulate the calculation method of the provider in order to track the remaining available units on the device.
