Number overview

0800-300-2449 is a toll-free number (the 0800 prefix). It is reported as a solicitation call from a fiber-line reseller.

Reported behavior

  • Drops the names of major ISPs to create the impression of credibility
  • Opens with framing such as "a notice about line-switching work"
  • Highlights only the benefits of switching, with little explanation of the downsides (cancellation fees, installation charges, etc.)

Solicitations from second- and third-tier fiber-line resellers are a known concern: they are not official communications from the underlying carrier, yet the wording is often crafted to make them seem like official notices.

How to handle this call

Ask "Which company are you calling from?" and confirm the company name; if you don't need the service, decline. Calling your current ISP directly is the easiest way to check whether a notice is genuine.
