• Communication is not possible even inside the
service area in places where the signal does
not reach (e.g. tunnels and basements). Also,
communication is sometimes not possible in poor
reception areas. Communication is sometimes
interrupted if you move into poor reception areas
during communications.
• Since this product uses radio waves, the possibility
of communication intercepts by third parties
cannot be eliminated. (Though LTE/WiMAX 2+/
GSM/UMTS system has highly secure confidential
communication features.)
• VoLTE (LTE network) by au is used when
connecting with emergency call receiving agencies
within Japan. You cannot connect through 3G
(circuit-switched network).
