- SIM Card is a "multi-cut SIM".
- Both voice calls and data communications are available in au's 4G LTE area (some areas support 5G). 3G communications are not available. Even within the service area, communications may not be possible or communications speeds may be slow. Communications may also be unavailable even in locations with good views, such as high floors in high-rise buildings or apartment buildings. For the latest area information, please check the au website. Communications speeds are a best-effort service and are not guaranteed to be consistent. Speeds may vary depending on your usage environment.
- Calls between au VoLTE compatible models (within au's 4G LTE area) will be of high quality. In other cases, the call will be made with the sound quality equivalent to that of the conventional one. The actual voice quality will vary depending on the radio wave environment and line congestion. au VoLTE compatible models cannot use 3G communication in Japan.
- Data communication amount during tethering connection is counted as J:COM MOBILE communication amount.
[About the amount including tax]
