If you don't know how to operate a smartphone or tablet... Recommended for those people! We support the use of smartphones (4G LTE/5G) by the remote operation of KDDI operator settings and operation methods. If you do not know how to set up or operate your smartphone (4G LTE/5G), we will support your use by remote operation by the KDDI operator. "Remote operation support" allows you to remotely "share" the screen of your smartphone (4G LTE/5G) (*1, *2, *3, *4) and guide you through various settings and operation methods. I will do it. You can rest assured that the operation will be performed while being confirmed by the customer. Note 1) Depending on the content of your inquiry, we may provide support by phone only. (Example: Delete data or enter password) Note 2) Depending on the content of your inquiry, we may not be able to resolve it. *3) Depending on the customer's usage environment, the screen may not be shared smoothly and this service may not be available. *4) Depending on the customer's model, the KDDI operator can understand the status of the model without sharing the screen (provided that the customer agrees). *Please be prepared as you will be guided by talking on a phone different from the smartphone (4G LTE/5G) that supports remote operation. * Separate packet communication charges will be incurred for starting icons when using each function, initial setting (starting setting), and remote operation support. * If you join/cancel during the month, the daily prorated amount will be applied.
