Frequently Asked Questions (FAQ)

Can I call and receive calls and texts via the Data SIM card?

"Data SIM" stands for internet-only SIM card. Therefore, texting or calling will not be possible via a Data SIM.

However, this refers only to Japanese network texts and messages. All internet-based messages such as Whatsapp, Viber, Telegram, Skype, Facebook Messenger, etc. will be available. Making internet-based phone calls such as Viber and Skype is also a great option for free communication with your friends and relatives.

What is the Data SIM internet speed and are there limitations?

The maximum internet speed of the Data SIM card reaches up to 75 Mbps. This is the highest mobile internet speed available to visitors in Japan.

There is no specific Internet limit. The only restriction is that you will have 500 Mb per day at the highest speed of 225 Mbps. After reaching this limit, the internet connection will slow down to 128 Kbps.

The following day you will once again have full access to a high-speed internet connection.

How long is the Data SIM card valid for?

You can choose the validity period of your Data SIM card when completing your order. You can select from either 15 or 30 consecutive days of SIM validity.

You will be able to make this selection upon completing your online order on this website. The beginning of the Data SIM validity period is determined by the activation date of the same. There is no special activation manual of the SIM. Once you insert it in your phone and it connects to the Japanese network, the SIM activates itself automatically. Once the selected validity period has passed, the Data SIM will no longer be active.
