What is the MNP code?

MNP (Mobile Number Portability) is a network service that allows mobile subscribers to switch networks that provide services and still retain their current phones.

In Japan, if you want to switch to a new network where the contract with the carrier you are using is still valid, you must pay a cancellation penalty fee of 9,500 won. Therefore, you should consider switching the MNP number at the end of the contract with the carrier, or at the time the other carrier has a big promotion to make up for the above payable penalty.
