Notice on Suspension in Taking New Applications for Asahi Net LTE ANSIM (Voice SIM card)
Due to increase in unintended usages of the service, we have stopped taking new applications for Voice SIM Card from those other than current Asahi Net members. At the present, we have not yet determined as to when we will resume taking applications from non-members. Applications from Asahi Net members are accepted.
Use ANSIM for cheaper smartphone charges. ANSIM is a SIM card service using NTT DOCOMO's network, and voice calls are possible. Both NTT DOCOMO and SIM free devices can be used. Reduce your smartphone charges with Asahi Net LTE (ANSIM)!
An Important Note For English Speakers
Although the ANSIM service is offered in English, the process of verifying the personal identification document that applicants for the ANSIM Voice SIM service are required to submit is currently only available in Japanese. Therefore, you may have problems with that part of the application process should you not understand Japanese, which may delay your application and ultimately the delivery of the ANSIM product.
Your understanding is appreciated.

Data rollover applies to those using the 3 Giga Plan, 7 Giga Plan, and 110MB/Day Plan. No applications or procedures necessary.
The maximum amount of data that can be rolled over into the following month is the maximum amount of data available each month specified by your Data Plan.
Data will be used in the following order: rollover data, additional (charged) data, and then the monthly data volume specified by your Data Plan.
