Good question! This really depends on your personal usage, but you can use the table below as an estimate.
| ACTIVITY | DATA |
| One email (text only) | 35 KB |
| One email with photo attachment | 1 MB |
| One email with Word, Excel or Power Point attachment | 300 KB |
| One webpage | 300 KB |
| One app/game/song | 15 MB |
| Social media download/upload | 500 KB |
| One 4 minute song | 600 KB |
| 1 minute of streaming video (e.g. Youtube HQ) | 30 MB |
The above estimates are measured in KB and MB. If you're not sure what these are, see the table below.
| UNIT | SIZE |
| 1 Kilobyte (KB) | 1,024 Bytes |
| 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.
