Super-cheap calls from your mobile

You just buy a £5 ‘phone card’ by text – there’s no actual card, it’s really just a PIN number. You use it every time you dial the Planet Numbers access number whenever you want to make a super-cheap call to Japan from your mobile. Here’s how it works:

  1. Text PLANET to 68888. This will cost you £5 plus the cost of one standard network text.
  2. We’ll text you a PIN instantly.
  3. Dial 0161 328 2820 followed by your usual FULL Japanese number including 00. You can find the per minute cost for calling all countries here on our tariff page.
  4. When you’ve used up your £5 just text PLANET to 68888 again.

Please note that if you’re a Virgin Mobile user you can’t currently use this service – .

Call Japanese landlines for 3p a minute – mobiles for 6p

With a Planet Numbers ‘phone card’, you can use any mobile, on any network (apart from Virgin) to make super-cheap calls to Japan . Calls to a landline cost 3p a minute, all day every day, plus a 5p connection charge. Calls to mobiles cost just 6p, all day every day, plus the 5p connection charge.

How international phone cards work

To buy £5 of international calling credit, text PLANET to 68888 from any mobile, apart from Virgin ones. We’ll text you back a PIN, instantly, and you can use our service immediately. There’s no ‘card’ involved!

To make a call, you just dial 0161 328 2820, then enter your PIN and your full Japan number, including 00. See below for a list of local dialling codes.

There’s a 5p connection charge per call but the cost of calling our 0161 access number will normally be covered by your regular ‘minutes’ allowance. Please check if you’re unsure.

Be careful not to press your phone’s Call button more than once or you might get charged for the call twice. You have a full 60 days to use your £5 credit. After this time you will lose any remaining credit and your PIN will no longer work. Please note that WE NEVER AUTOMATICALLY RENEW your phone card.

To add another £5, simply text PLANET to 68888 as before.

If the line’s engaged, hang up!

If the international number you want to chat to is engaged, or nobody answers, hang up. Your network supplier may charge you for the call to our 0161 line even if you don’t complete the international call. Most mobile users will be covered by their regular monthly minutes allowance, of course.

Slash the cost of calling Japan

It really couldn’t be simpler to save yourself a fortune on your overseas calls to Japan. With Planet Numbers’ International Call Saver service, all you have to do is dial a special international access number immediately before you dial your normal overseas number. In this case, after dialling our access number you would simply key in your normal number in Japan (ie you need to key in the full international dial code, not forgetting the zero zero at the start of the number).

This means that your call to Japan is now handled by Planet Numbers, instead of your usual provider, and therefore the call will be charged to you at only 3p a minute, regardless of when you call or where in Japan you’re calling. So, in a nutshell, to start making cheaper calls to Japan, instead of just dialling the Japanese number directly, you call 0843 718 7777 first (this is the access number).

Once connected to Planet Numbers you’ll hear a second dial tone. Now dial the full Japanese phone number you wish to reach - don’t forget you need to start with 0081 as usual. For example, to call a number in Tokyo, you would dial 0081 + the local number.

To end your call, hang up in the usual manner. And if you’d like to make another international call, just redial 0843 718 7777 first. Simple.

Please note: our current super-cheap per minute rate to Japan of 3p is a fixed rate when you’re calling from a BT landline to an Japanese landline. The cost of calling Japan from your mobile phone may vary but currently can be as little as 3p a minute. Click on the links at the top of the page to find out more about calling Japan from a mobile.

Save a massive 17p per minute vs BT

The call will appear on your bill in the normal way, but the number dialed will show as 0843 718 7777. More importantly, instead of paying 20.00p per minute to call Japan via BT, you’ll simply have paid 3p a minute … all day, every day.

No sign-up or registration required – try it right now!

When you use Planet Numbers’ international call saver service to call Japan from your landline, you’ll simply pay 3p a minute, all day every day.

If you’d made exactly the same call, for exactly the same length of time, using BT’s international sevice instead of ours, you’d end up paying 20.00p per minute! In other words, by using Planet Numbers you’ll save yourself a massive 17p every single minute you’re on the phone to Japan!

No sign-up or registration required to use the service – try it right now and save ££s

You don’t need to register for Planet Numbers International Call Saver service, and there are no passwords, codes or PINs to remember. All you have to do is make a note of the special access number that you need to dial in order to make these super-savings from any UK landline when you call Japan: 0843 718 7777.

Call costs to Japan that are just too good to be true?

It sounds almost too good to be true, doesn’t it? Perhaps you’re thinking “Where’s the catch? How can I call Japan for so little when other phone networks charge me so much?” Well, there isn’t one!

We can charge you just 3p a minute for every call you make to Japan (plus your phone provider’s access charge) simply by diverting your call via our own network and therefore not having to pay for the use of BT’s international phone system.

Planet Numbers International Call Saver service even works when international call barring is activated on your phone – which is why you can use us to call Japan from a phone box too. When you call Japan using Planet Number, the phone thinks you’re dialling a UK number … which indeed you are - the Planet Numbers access number. The phone doesn’t need to know that you’re dialling an international number immediately after!

How will the Planet Numbers call to Japan appear on my next phone bill?

When you use Planet Numbers to make a super cheap call to a landline, or mobile, in Japan, the call will, of course, appear on your phone bill. But instead of appearing as an international call (in this case, to Japan) the international call will simply be shown as the Planet Numbers UK access number.

So instead of the familiar number in Japan appearing, you’ll simply see 0843 718 7777. It’s always a good idea to make a note of the Planet Numbers access number for calling Japan so that when your bill arrives you, or whoever looks after the payment of your bill, recognises the call. One thing is for certain, however, you’ll be sure to appreciate how tiny the cost of calling Japan has become – especially if you’re used to seeing the price of an international call to Japan from the likes of BT!

Make cheap calls TO Japanese mobiles – just 5p a minute (plus your phone provider’s access charge)

You can make incredibly cheap calls to Japanese mobile phones from any UK landline using Planet Numbers International Calls Service. You simply dial 0843 723 7777, followed by the full Japanese mobile number that you wish to call, starting 0081 as usual.

Calls to Japanese mobiles using 0843 723 7777 are charged at just 5p per minute at all times (plus your phone provider’s access charge).

The return message you receive will cost £5 (inclusive of 20% VAT) from O2, Vodafone, EE, Orange, T Mobile and 3G billed to the account holder for that line. Always make sure you have the bill payer’s permission before you use this service. We will credit you with calling credit (as per our tariff) and issue a PIN to that value with a UK geographic landline telephone number to access the service.

Calls to the UK geographical landline number (0161 328 2820) will be charged as per your mobile network price plan to a UK geographical landline, or may be part of your monthly inclusive minutes allowance. Please check with your service provider to confirm this.

Calls are charged by the minute and subject to a 5p connection charge on all calls (all quoted prices are inclusive of VAT, and apply 24 hours a day, 7 days a week when using the 01 access number).
