The following are procedures and important considerations for using an au IC card (SIM card) with another company's mobile phone.
Please make sure you have read and understood the "Important Considerations Regarding Usage of Non-au Mobile Phones" and, if necessary, go to your nearest au Style / au shop for help with the procedures.
In order to use the Internet on a non-au mobile phone, you will need to sign up for "LTE NET for DATA" and then set up an Internet connection. Please be aware that you cannot connect to the Internet via "LTE NET" when using a non-au mobile phone.
With regard to fee plans, discount services, etc., the same fee structure which is used for au mobile phones is also used for all non-au mobile phones.
Please be aware that if you are not signed up for a flat-rate data (packet) service, you may experience unexpectedly high packet communication fees.
You are thus strongly encouraged to sign up for a flat-rate data service. Please also be aware that non-au mobile phone users cannot take advantage of the LTE Single (data communication terminals, tablets, etc.) fee plan and discount service.
Repairs and other after-service for non-au mobile phones is not handled by au. Please contact the company from which you bought your phone about how to handle repair issues.
Excluding cases of willful or gross negligence, au is in no way responsible for anything which may result from using an au IC card in a mobile phone or other device sold by another company.
