The call fee and SMS transmission fee will be charged two months later, so the total amount of the monthly fee and the call fee and SMS transmission fee will be settled two months ago.

The maximum communication speed for this service is 500 Mbps on receipt and 50 Mbps on transmission. If your monthly data traffic exceeds the specified high-speed data traffic, the transmission speed will be up to 200 kbps until the end of this month. In addition, the stated communication speed is the maximum value according to the standard and is not guaranteed as an effective speed.

Transmitting and receiving large amounts of data in a short period of time that may affect other customers’ use may temporarily limit the speed of communication.
NTT DoCoMo’s services such as SP mode and SP mode mail are not available unless you have an extended contract with mail server with NTT DoCoMo.

The basic fee is charged for one month without calculating the daily rate.
All-you-can-call option is an optional service that can be used GB with a voice plan, and free calls are applied during the hour without a dedicated application or leading number.

The all-you-can-call option is for domestic calls, not for “104” or other service calls or international calls.
Please be sure to read the SIM card and enclosed documentation as there are precautions for the unlimited call option.

The all-you-can-call option will be applied at the same time as you start using the new calling number, and in the case of MNP, it will be applied at around 10 a.m. the next day after the opening date.
