Calling within Japan
How is World Link different from NTT, KDDI, etc?
The answer is simple: We offer cheap phone calls at flat rates 24/7 for calling anywhere. NTT and KDDI have very high rates that only get cheaper at certain times, or with discounts for calling preselected numbers.
Why is it so cheap?
World Link uses its large customer base to negotiate cheap international calling rates from large carriers. And since we don't publish big flashy ads, there's no need for a large advertising budget. This allows us to pass on the savings to our customers.
How will World Link save me money on my mobile phone?
When you use World Link for domestic or international calls on your Japan mobile phone you don't get charged by your mobile company for those calls, nor do you use any of your mobile's monthly minutes. You can switch to your mobile company's cheapest calling plan - one with fewer "free" minutes - to save more money.
Is the sound quality okay?
Yes, it's excellent. World Link is not an IP phone service so there aren't the sound quality problems or technical problems that IP phone systems have. World Link calls go over the fiber-optic lines of major international carriers.
Do I need special equipment to use World Link?
No, you don't need to buy or install anything at all. Just use your phone as usual.
I've already registered with KDDI (or NTT). Can I use World Link also?
Yes, you can use World Link. You don't have to change your registration with these other companies.
I have Myline service. Can I use World Link?
Yes. You don't need to change your Myline service at all - just leave it as it is.
I have an ISDN (or ADSL) line. Can I use World Link?
Yes. But for ISDN, when you register with us you must register both of your numbers if you have two - your main number and your 2nd (sub) number.
I have cable phone (from my cable TV company). Can I use World Link?
No, you cannot. For land lines, only standard NTT lines – not IP phones, like Hikari Denwa or cable TV company lines – can be registered. You can use World Link on your mobile phone though.
I have Yahoo!BB phone. Can I use World Link?
No, you cannot. You can use World Link on your mobile phone though.
I have IP phone service. Can I use World Link also?
No, you cannot. For land lines, only standard NTT lines – not IP phones, like Hikari Denwa or cable TV company lines – can be registered. You can use World Link on your mobile phone though.
Can I use World Link with my mobile phone? What are the rates?
Yes, you can use World Link on your mobile and save a lot of money. Please see our mobile phone rates page.
Can I send faxes with World Link? What are the rates?
Yes. The rates are the same as for telephones - see our rates page.
Can I call toll-free numbers abroad?
Yes, you can call most toll-free numbers abroad, but you will be charged.
Will I get a separate bill from my mobile company for my World Link calls?
No. When you use World Link for cheap international calls, or local and long distance calls within Japan, you don't get charged by your mobile company for those calls, nor do you use any of your mobile's monthly minutes.
How do I make a call using World Link?
First you must register your phone with us. After that, you just pick up your phone and call. See our How to Call pages for details.
I see the rate, but how much will I pay if I talk for 10 minutes?
Just multiply the rate by the number of minutes you talk. So if you talk for 10 minutes, your bill will be 10 times the rate. That's all.
Is there a different form or procedure for corporate registration?
No, there isn't. Please use our regular registration page.
Do I have to give you my email address?
Yes. Email is part of the registration process, so we must be able to reach you by email.
Is my email address, credit card information, etc. safe with your company?
We do not send unnecessary marketing email or junk email to our customers, nor do we divulge customer information to anyone else. Please see our privacy statement for details.
When can I start using the service?
If you request it, we will email you when we finish registering your numbers. That usually means 1 working day after we receive an registration form. You can start at that time. (We also send new account information by post.)
How will I be contacted when my new service is ready to use?
If you request notification by email when you sign up, you'll get that email. And all customers receive notification by post.
Can I make domestic calls on my mobile phone in Japan?
Yes. Please see our rates for calling in Japan on mobile phones.
Can I call to any phone in Japan?
You can call to all mobile phones (keitai) and telephones (land lines), but not 070 PHS phones.
What increments are calls charged in?
Calls are charged in 1-minute increments. So, for example, if you talk for 10 minutes the charge is simply 10 times the rate for that call.
Can I get all the help and information I need in English?
Yes. You can contact us by phone or email in English.
How do I cancel my World Link service?
Just contact us through our website, or by phone, fax, email or post.
