When performing these procedures

Bring your SIM-unlocked non-au mobile phone or device [1] [2] with you.

  • [1] The au IC card can only be used with mobile phones or devices that are compatible with the communication methods and frequency bands provided by au. Before applying, check with the company from which you purchased the device for details about the communication methods and frequency bands that are supported.
  • [2] Before using, it will be necessary to check that the device has received certification of conformance to technical standards. Use of a non-au mobile phone or device that does not bear the "Giteki" (technical conformity) mark is a violation of Japan's Radio Act and may not be allowed to connect to the au network.

<For customers without an au contract>

  • Rate plans are the same as when using an au mobile phone.
  • As a general rule, the au Nano IC Card (LTE) or au Micro IC Card (LTE) is provided for devices that support CDMA2000, and the au Nano IC Card 04 (au VoLTE) is provided for other devices.

*A "(V)" is appended to the names of rate plans and data flat-rate services for 4G LTE (au VoLTE compatible) Android™ smartphones.

<For customers with an au contract>

*If changing the contract between WIN/LTE/VoLTE or switching between an LTE Single (data communication terminals, tablets, etc.) and Dual (smartphones) contract without purchasing a mobile device, a contract change fee of ¥3,000 will be charged.

Important considerations regarding usage of non-au mobile phones

Confirmation and guarantee of operation for au IC cards

  • Since au does not confirm the operation of au IC cards when used with non-au mobile phones, au makes no guarantee regarding IC card operation for communications, including voice calls and data transmission. It is up to the customer to confirm how to set up and use a non-au mobile phone, and all relevant inquiries should be directed to the company from which the device was purchased.
  • The use of services, content, device functions, downloaded applications, and other features may be limited when using a non-au mobile phone. Please note that you will be charged the monthly fee for services and content, even if you are unable to use them on your non-an mobile device.

Setting up an Internet connection

To use the Internet on a non-au Android mobile phone, you will need to sign up for LTE NET for DATA and then set up an Internet connection. Please note that you cannot connect to the Internet via LTE NET when using a non-au mobile phone (Android devices).

Customers who use packet communications on a non-au Android mobile phone must set the access point. For details see the LTE NET for DATA page.

Usage Fees

With regard to rate plans, discount services, etc., the same fee structure used for au mobile phones is also used for all non-au mobile phones. Please note that if you are not signed up for a data (packet) flat-rate communication service, you may experience unexpectedly high packet communication fees. It is therefore strongly recommended that you sign up for a data (packet) flat-rate communication service. Also, please note that the LTE Single (data communication terminals, tablets, etc.) rate plan and discount service is not available to non-au mobile phone users.

Repairing non-au mobile phones and devices

Repairs and other after-sales services for non-au mobile phones are not handled by au. For information on how to handle repair issues, contact the company from which you purchased the device.

Exemption of Liability

Except in cases of willful or gross negligence on the part of au, au shall bear no responsibility for any loss, damage, or trouble that may result from using an au IC card in a mobile phone or other device sold by another company.
