World Link FAQs

Here are some common questions about calling in Japan, international calls from Japan, and our cheap mobile phone service. Click on the questions to see their answers. If you don't find the information you need, please contact us.

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.
