Number overview
0800-714-7436 is a number with many complaints about a predatory operator that disguises itself as commissioned by NTT and aggressively pushes a fiber-line switch. It is not a legitimate NTT phone number.
Reported tactics
- The caller introduces themselves as "calling on behalf of NTT to verify your line"
- The caller claims your current line is outdated or that your bill will drop
- Without consent, the caller proceeds unilaterally with "We'll start the procedure"
- If the call goes unanswered, the caller continues talking to themselves (likely an automated voice)
NTT does not commission third parties to solicit line switches by phone. The Ministry of Internal Affairs and Communications has issued administrative guidance against this kind of predatory fiber-line sales.
How to handle this call
Don't pick up
The best approach is not to answer unfamiliar 0800 numbers.
If you do answer
Don't share details of your current contract. Say "I don't need it" and hang up.
