What is tethering?
Tethering is a function that enables you to connect various devices such as a notebook PC, tablet or game console to the Internet outside the home by using a smartphone as an access point.
There are three types of tethering (connection methods between a smartphone and device) to choose from: Wi-Fi, Bluetooth® and USB. Choose the method that suits your use.
- The type of tethering that can be supported differs depending on the smartphone model.

Notes

- The monthly usage charge of the Tethering Option is not calculated on a prorated basis.
- Additional packet communication charges are incurred at the time of use. The packet communication charges when using tethering are eligible for your contracted data flat rate service or rate plan.

- If you change between a rate plan/Flat-rate Data service that makes the Tethering Option monthly charge free and a rate plan/Flat-rate Data service that makes the Tethering Option monthly charge ¥550 (tax included), your monthly charge in the month of your device change is ¥0. However, the 500 MB data increase benefit that comes with changing your monthly charge to ¥550 (tax included) applies to the month of your device change.
- When connecting to the Internet via tethering, it may not work correctly depending on your usage environment and external connected devices.
- EZweb sites are not available.

Restriction of communication speed
- Customers who have used a large amount of data within a certain period of time are subject to data transmission speed limitations during traffic-heavy times of the day.
- Regardless of whether you are subscribed to a data (packet) flat rate service, your line may be temporarily suspended if the cost of the packet communication you use becomes high.
- If the total amount of communication exceeds the monthly data amount, the maximum communication speed for sending and receiving until the end of that month will be 128 kbps.
