Q1:
What kind of a service is MYLINE Carrier Selection Service?
A1:
With MYLINE Carrier Selection Service, once you have registered your telephone company (carrier) choice in advance, you can use that telephone company without dialing its access code. However, you can still use a different telephone company if you dial that telephone company's access code.
If you dial from a telephone that has ACR, LCR, or an adapter, you will use the telephone company assigned by the ACR.

* ACR (Automatic Carrier Routing): a function that automatically selects the telephone company (formerly called LCR or Least-Cost Routing).

Q2:
What kind of a service is MYLINE PLUS Carrier Designation Service?
A2:
People who always use the same telephone company are recommended to use MYLINE PLUS Carrier Designation Service. With MYLINE PLUS you only use the telephone company you've registered, even if you dial a different telephone company's access code.
Therefore, your phone automatically uses the telephone company you've registered for MYLINE PLUS, even if your telephone is equipped with ACR or an adapter. Please contact your telephone company (carrier) if you have questions about ACR.
However, if there is an earthquake or other emergency and you can't use the telephone company you've registered, you can use a different telephone company. Just dial the prefix "122" to temporarily cancel your registration, followed by the access code of the other telephone company.
Q3:
I am using a telephone equipped with ACR (LCR).
Will I be unable to use the telephone company that ACR (LCR) selects?
A3:
With MYLINE Carrier Selection Service, your phone will automatically give priority to letting ACR select the telephone company over your registered telephone company.
With MYLINE PLUS Carrier Designation Service, your phone automatically gives priority to the telephone company you've registered.
Please contact your telephone company (carrier) if you have questions about ACR.
With MYLINE PLUS, your phone will let you know that you've been connected via your registered telephone company in one of the following ways:

1) Customers who use an ordinary subscriber phone will hear voice prompts to indicate which telephone company they are being connected to.

2) Customers who use ISDN (voice, 3.1 kHz audio) will hear voice prompts and/or see a display showing the number of the telephone company they've been connected to.

3) Customers who use ISDN (64 kb/s asynchronous digital) will see a display showing the access number of the telephone company they've been connected to.
None of these cases indicates a malfunction of your phone or your phone line. In some cases, depending on the telephone company, there may be no voice message or display of the carrier's access number.

Q4:
Why is MYLINE Carrier Selection Service being introduced?
A4:
Using MYLINE Carrier Selection Service will benefit you by eliminating the need to dial a telephone company's access code (the way you used to have to dial).
With the introduction of MYLINE, all telephone companies in Japan will have the same number of digits in their dialing prefixes. Fair competition among the companies will invigorate the market, setting the stage for even better services in the future.
Q5:
Why is MYLINE PLUS Carrier Designation Service being introduced?
A5:
It is being introduced to benefit customers. MYLINE PLUS will enable customers to select and use telephone companies according to the calling category. In addition, it will allow customers to change their telephone company just by submitting an application, eliminating the need to cancel the ACR function or make other adjustments to customers' telephone equipment.
Q6:
What are "calling categories"?
A6:
"Calling categories" refers to four categories: local calls, in-prefecture long-distance calls, out-of-prefecture long-distance calls, and international calls. MYLINE customers can select and register telephone companies in any or all of these four categories.
"Local call" means a call within the same local calling area; for example, a call within the Tokyo "03" calling area.
"In-prefecture long-distance call" means a call outside the local calling area but within the same prefecture; for example, a call from the Tokyo "03" calling area to the Hachioji City calling area.
"Out-of-prefecture long-distance call" means a call from one prefecture to another prefecture; for example, a call from the Tokyo "03" calling area to Osaka.
"International call" means a call from Japan to somewhere outside of Japan ."

Q8:
What if I haven't registered?

Even if you haven't registered, you still can make telephone calls in the same way as before. Local calls and in-prefecture long-distance calls will automatically go via NTT East or NTT West. Out-of-prefecture long-distance calls will automatically go via NTT Communications.
If you're making an international call but haven't registered, you'll have to dial the international telephone company's access code.
If you dial from a telephone that has ACR or an adapter, you will use the telephone company assigned by the ACR.
Q9:
Why is the telephone company's access codenecessary when I apply in the international calling category?
A9:
Since before the start of MYLINE services, all telephone companies have been requiring the telephone company's access code to be part of the dialing sequence for all international calls because registration of a specific telephone company would raise issues of fair competition.
Q10:
What is new and different now?
A10:
MYLINE services eliminate the step of dialing the telephone company's access code (which previously was necessary).

Q11:
Can I keep on using the telephone equipment that I'm using right now?
Will I have to buy a new telephone?

With MYLINE PLUS, your phone automatically gives priority to the carrier you've registered, even if you have ACR.
Be alert for scams! Some people may try to sell you unneeded telephone equipment by saying that you won't be able to keep on using your current telephone equipment, ACR, or adapter if you use a MYLINE service.
Q12:
If I have registered one telephone company for MYLINE PLUS, can I use a different one?
A12:
If there is an earthquake or other emergency and you can't use the telephone company you've registered, you will be able to use a telephone company that you haven't registered. Just dial the prefix "122" followed by the access code of the other telephone company.
Q13:
Will the dialing order for international calls change?
A13:
The dialing sequence differs, as indicated below, depending on whether you are registered in the international calling category or not.

* If you are registered with MYLINE or MYLINE PLUS, dial
010 + the country code + telephone number in the destination country

* If you are NOT registered with MYLINE or MYLINE PLUS, dial
the telephone company's access code + 010 + the country code + telephone number in the destination country

* If you are using a mobile/cell phone, PHS, or a public telephone, dial
the telephone company's access code + 010 + the country code + telephone number in the destination country
