When using MNP to transfer your number, you are ending (cancelling) your subscription with your current carrier and starting a new subscription with the new carrier. Because of this, you should be aware of the following points:

About purchasing in installments

If there are any outstanding installments when you apply for cancellation, you will still be required to pay the installment payments. Canceling your subscription will result in the termination of your Monthly Support, and charges will be made without the discount deduction.
If you pay the lump sum of the remaining installment payments to cancel your subscription to the service, the DOCOMO installment payment contract (individual credit purchase brokerage contract/installment sale contract) can be terminated.

About points

[In the case of d POINTs (Under a personal name)]
Make sure you are issued a d ACCOUNT before cancelling your mobile phone subscription. If you have a d ACCOUNT, you can continue using d POINTs with some services as a member of d POINT CLUB after cancelling your mobile phone subscription. If a d ACCOUNT is not issued, you will not be able to continue using d POINT CLUB, and your d POINTs (also including points earned with your d CARD or d POINT CARD) will be forfeited.
