0077/001 Landline phone call charges

I was charged for a landline phone that I do not recognize

If you call a phone number preceded by the identification number "0077" or "001", you will be charged by KDDI.

How KDDI billing works

Termination of "My Line" [マイライン] service

  • "My Line" [マイライン] was a service that allowed you to make calls without dialing the telephone company's identifier number, by setting up in advance the telephone company you want to use

  • The telephone company selection service "My Line" [マイライン] ended in January of 2024

Impact of the termination of "My Line" [マイライン]

While you were using "My Line" [マイライン], your billing was by the telephone company with which you registered your My Line service.

With the termination of "My Line" [マイライン] service, if your phone has been assigned the KDDI identification number "0077" or "001" in its settings, you will be billed by KDDI.

This automatic assignment is achieved by the ACR/LCR function (a function that automatically selects a pre-set telephone company when making a call) and is available in both built-in and external types.

This setting may unintentionally cause billing from KDDI.

If you have checked all of the above and still do not recall
