What is the difference between unmetered and metered bandwidth?

Example: 1mbps unmetered or 150 GB Bandwidth

In the example above – you have two options for your bandwidth allotment. The first one is 1mbps unmetered. This translates to your bandwidth being unlimited – however its speed is capped at 1mb per second. The alternative of 150GB metered – means that your bandwidth is tracked to a cap of 150GB – but you are able to utilize the full speed of the bandwidth pipe – most often 100mbps.
