Number overview
0800-777-9017 is a toll-free number (the 0800 prefix, equivalent to Free Dial). Multiple reports describe calls from this number as sales pitches pushing a switch to a different internet fiber-line provider.
Reported behavior
Typical patterns reported for this number include:
- The caller does not give a specific company name and uses vague openers like "a notice about line work" or "a notice about lowering your fees"
- Attempts to extract details about your current contract or personal information
- Pressure tactics such as "rates will go up unless you switch right now"
- Phrasing that misleads listeners into thinking the caller is affiliated with NTT or a major ISP
The Ministry of Internal Affairs and Communications has communicated that solicitations for telecom services must clearly state the company name and contract details. Solicitations that hide the company name may violate the Act on Specified Commercial Transactions.
How to handle this call
Verify the company name and the purpose of the call
If you answer, first confirm the caller's company name, the representative's name, and the specific purpose. If you only get vague answers, the call is most likely a sales pitch.
Don't sign anything on the spot
Do not agree to any contract change over the phone. A legitimate provider will be willing to send a written explanation and give you time to consider.
Cooling-off rule
Phone-solicitation sales of telecom services are covered by Japan's initial contract cancellation rule (the equivalent of cooling-off). You can cancel the contract unconditionally within 8 days of receiving the contract document.
