Myline is a phone company selection service provided by NTT East/NTT West that allows you to register a preferred phone company in advance and then always use that phone company when making calls without having to first enter the company's identification number (which is 0077 or 001 in the case of KDDI). Myline has two varieties: Myline and Myline PLUS. With either of these you can choose your preferred phone company for each of four calling areas (out-of-town calls, in-prefecture but out-of-town calls, out-of-prefecture calls, and international calls).
To receive up to a 50% discount on your international calls, register KDDI as your service provider for Myline or Myline PLUS and apply for DANZEN TALK II DX and DANZEN NENWARI. Register KDDI as your service provider for Myline PLUS in three or more calling regions (including in-prefecture and out-of-prefecture calls) to eliminate your DANZEN TALK II DX fixed-rate monthly fee. You can also waive this fee by using Internet au one net, an au mobile phone, or a Willcom PHS phone and filling out a special application form.
* Please dial 0057 (No area code/Toll Free/24-hour support) to request the application form.
