|1 Megabyte (MB)||1,024 Kilobytes|
|1 Gigabyte (GB)||1,024 Megabytes|
When data is consumed, it is used in batches of 10KB (10,240 Bytes to be precise) at a time - these are called pulses. Your data consumption is measured in volume (Bytes) by the system and rounded to the nearest 10KB. This is then deducted from the data included in your plan.
