The right answer for the question is a “NO”.

The truth is unlimited bandwidth is only possible if the website hosting company possess their own internet broadband company. If they have own broadband company, then it is possible to offer their customers unlimited bandwidth per second.

So why do unlimited bandwidth hosting plans exist?

However, that’s not the full stop for our story.

To be fair, the bandwidth limitations we are talking about here are almost incomprehensible and would never be reached by a single website. Thus in practical, a hosting company could actually (very much) offer virtually unlimited bandwidth to its client.

Most websites only consume a very small amount of bandwidth and disk space. Web hosting companies that provide unlimited anything as a plan feature are banking on the fact that you won’t use very much.

This is the controversial area between truth and falsehood upon which marketing claims feed.
