Safety Information - Huawei Mate 9 Quick Start Manual

Dual card dual standby single pass
MHA-L29: Your phone supports only dual card dual standby
single pass, which means you cannot use both SIM cards for calls
or data services simultaneously.
•
When you are on a call using SIM card 1, SIM card 2 cannot
be used to make or answer calls. If someone calls SIM card 2,
the caller will hear a voice message similar to "The subscriber
you dialed is out of the service area" or "The subscriber you
dialed cannot be connected for the moment, please try again
later." The actual message will vary by service provider.
•
When you are using SIM card 1's data service, SIM card 2's
data service will be disabled.
Your phone's single pass feature helps reduce power consumption
and increase your phone's standby time. It is not related to your
service provider's network conditions.
It may be a good idea to contact your service provider and
subscribe to missed call reminder and related assistance services to
avoid the conflicts mentioned above.
