● For coverage areas, please refer to the following page: https://www.nttdocomo.co.jp/corporate/disclosure/mvno/user

INITIAL CONTRACT TERMINATION POLICY
※ This initial contract termination policy applies only to individual customers who have subscribed to an eligible “Voice Call Plan” (hereinafter referred to as an "Eligible Plan"). Customers with a plan other than an Eligible Plan are not covered under this policy.
The date the customer receives the “Detailed Contract Explanation” from us—after registering for the service—marks the beginning of the applicable period (for customers who opted to receive this document electronically during the sign-up process). Within eight (8) days from either the contract registration date or the service start date (whichever is later), customers may cancel their contract under this policy (“Initial Contract Termination Period”) by submitting a written notice of cancellation. The notice must include the registration date, registered name, address, phone number, and the name of the service to be cancelled. It must also be signed and sealed, then mailed to the designated address below. This cancellation is based on the Initial Contract Termination Policy as stipulated in the Telecommunications Business Act.
Furthermore, if the customer transferred from another carrier using MNP at the time of contract registration and wishes to cancel under this policy, the MNP transfer procedure must be completed during the Initial Contract Termination Period.
Please note that customers must complete the process themselves via their My Page to obtain an MNP Reservation Number (MNP Yoyaku Bangō)—we cannot apply for this on your behalf. If cancellation is performed alongside MNP, the cancellation date under this policy will be either the date the MNP transfer is completed or the expiration date of the MNP Reservation Number, whichever comes first.
Also note:
● MNP Reservation Numbers cannot be reissued or extended.
● If the customer obtained a new phone number when registering for the Voice Call Plan and wishes to cancel under this policy, MNP procedures will not be available.
