After exceeding your monthly data plan, the internet speed will become low-speed mode.

When it's become low-speed mode, the speed will be 200 Kbps. If you use 366 MB of data within 3 days while in low-speed mode, the internet speed becomes even slower (down to 40 Kbps).

※You will not get any notifications about data usage warnings from us.

The full amount of your monthly data limit will be available again on the 1st of the following month.

If you need more high-speed data for that month, there is an option to make a TopUp.

You can top up more data to your SIM card for this month by logging into the Sakura Mobile My page.

※Top-up is only available for the credit card payment method. (Not available for cash payment contractors.)

For more detailed instructions on how to top up from the Sakura Mobile My Page, please check the link below:
