Smartphone Reseller in Japan

Smartphone Reseller in Japan Money

If you look at Japanese auction sites and flea market apps, you’ll often see individuals selling their new smartphones. In this article, we will explain how these people make a profit.



First of all, you need to know about MNP, which stands for Mobile Number Portability, as it offers a number of benefits not available with a new contract, such as cheaper smartphones and cashback.

If you repeatedly use MNP with many smartphones, you can earn big profits.

How to make money with MNP

Get a phone number

If you don’t have a phone number that you can switch to, you need to get a number. 

These days, you can get a phone number for 0 yen as long as you have a smartphone.

If you don’t have a smartphone, you can buy a second-hand one for around 3,000 yen and get a phone number.

Find a profitable shop

Look for shops that are offering cashback and other promotions.

It is important to note that the same carrier may or may not have different campaigns at different shops, and the details of these campaigns may differ.

The content of a dealer’s campaign is decided by them.

The shops are assigned a quota by the carrier.

If they are strict about meeting this quota, they tend to run quite large campaigns.

If you check a few shops around you, there is a big chance that the contents will be different.

Make sure you sign a contract with a place that offers better conditions.

Sign the contract

If you find a campaign that appeals to you, it’s best to sign up as soon as possible.

Many of the bigger offers are only available for a short time.

You may find that the offer has expired.

There is no need to do anything special to sign up, just follow the normal procedure and you will receive your cashback.

Receive your cashback

This will depend on your contract details.

In some cases, you will receive your cash back immediately, but in other cases, you may not receive it until a few months later.

The method of receiving your cash back also varies from shop to shop.

Some will give you cash, others will give you gift vouchers.

You can find out more about this on the shop’s website, so it’s a good idea to check informations there.


Once you have received your cashback, you should cancel your contract as soon as possible.

In fact, the bigger the cashback and the more expensive the phone, the higher your monthly mobile phone bill will be.

The longer you wait to cancel your contract, the more you’ll lose.

So we recommend you to cancel your contract as soon as possible.

Important notice

It is not advisable to do this too often.

Some carriers have a blacklist.

If you are blacklisted, you may not be able to sign a contract with that carrier for a certain period of time.

The blacklist is shared by all shops in Japan, so you may not be able to sign a contract with the same carrier even if you change shops.

It is said that some mobile carriers do not have a blacklist.

One of the most famous carriers is au.

In order not to get on the black list, many people make a 6 month contract for MNP.
