Mobile Phone in Japan(3): MNP Procedure, What You Need to Know about Your Mobile Phone Contract

If you are currently under contract for smartphone communication with a major telecommunications company and want to switch (MNP) to another company that offers a plan with a lower price, but the procedure is confusing, we have compiled the MNP procedure for such people to understand what is required.

What is MNP?

MNP stands for Mobile Number Portability, a system that allows you to move to another telecommunications company without changing your phone number.

Difference between MNP, New Contract, and Change of phone model

New Contract

In a new contract, you sign a new line contract with a telecommunications company.

Therefore, if you have a phone number under contract, that number will remain. And you will have two phone numbers.

Change of phone model

Changing the model of the phone is done while continuing to have a telecommunication contract with the same telecommunication company, without changing the phone number in use.

The only changed thing is the phone modal.

What you need for MNP

MNP allows you to transfer a telecommunication contract with the same phone number, but four things are required before transferring out, transferring in & opening a new contract.

  1. MNP reservation number
  2. Identification documents (driver’s license, passport, etc.)
  3. Credit card or bankbook (plus personal seal)
  4. Fees associated with transferring out and in

MNP Procedure

Once you have decided on a communication plan for the destination you wish to move to, you will need to make an MNP.

For example, if you have a contract with AU, you can change your contract to ahamo (MNP) with the same phone number. The procedure is as follows.

1. Apply for MNP transfer (with the telecommunications company with which you have a contract)

Complete the MNP transfer procedure with your current telecommunications carrier. With major telecommunications carriers, MNP transfer can be made with a single phone call. Call and apply for MNP transfer. You can also do this at a store, but it takes much longer.

2. Have your MNP reservation number issued (by the telecommunications carrier with which you have a contract)

Ask your current telecommunications carrier to issue an MNP reservation number.
Some telecommunications carriers issue MNP numbers online, so if possible, ask your carrier to issue the number online.

3. Application for MNP transfer (to a new telecommunications company)

Complete the MNP transfer procedures with the telecommunications carrier to which you plan to transfer MNP. At this time, an MNP reservation number is required, so proceed with the MNP transfer procedure after obtaining one.

To verify your identity, you will need to present or submit your driver’s license or passport, and a credit card or bankbook as a means of payment.

MNP is a quick process

If you want to switch to a new, less expensive communication plan online, such as ahamo, MVNO, Rakuten Mobile, etc., you can apply for a new communication company in advance and have the SIM card, etc., in hand, so that you will be able to communicate with your new communication plan immediately and in advance. Be prepared.
