- SIM Card is a "multi-cut SIM".
- Both voice calls and data communications can be used in au's 4G LTE area. 3G communication is not available. Even within the service area, communication may not be possible or the communication speed may decrease. In addition, it may not be possible to use the product even in places with a good view, such as high-rise buildings and condominiums. Check the au website for the latest area information. Communication speed is a best effort service and does not guarantee a constant speed. It varies depending on the 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]
