How to use
Notes on the application process
- When applying for prepaid service mobile phone procedures (new contracts, model changes, address changes, etc.), original identification documents are required.
- Regarding new contracts and model changes, usage is possible after customer information has been registered and the registered individual is the contractual party.
- If the user is a minor, parental consent is required via a "Parental Consent Form" (the consent section in the contract form) (However, when an elementary school age child is contracted, a parent must be present and that parent completes the procedures in place of the contractual party. In that case, identification documentation for that parent is required.).
- If the contractual party changes, contract transfer procedures are absolutely necessary. The signature and seal of the transferring party and original identification documentation for the receiving party are required for the transfer procedures.
- When subscribing to a new prepaid service, a contract fee of ¥4,000 is required. Also, a prepaid card of at least ¥6,000 must be purchased at the same time.
- When changing to an au mobile phone (a model that is not compatible with an au IC card), a charge of ¥4,000 is required. When changing to an au mobile phone that is accompanied by the issue of an auIC card (a USIM card), a charge of ¥2,000 is required. However, when changing an au mobile phone (a model that is not compatible with an auIC card) to an au mobile phone that is accompanied by the issue of an auIC card (a USIM card), the charge is free.
