Dual-Card Dual-Standby
Your mobile phone supports dual-card dual-standby mode,
which can significantly reduce power consumpt ion and increase
your phone's standby t ime. Note that two restrict ions exist:

When you make calls using one SIM card, the other SIM card
is disabled.
For example, when you make calls using SIM card 1,
SIM card 2 cannot be used to answer calls or access
the Internet. If someone calls SIM card 2, the caller
will hear a voice message like "The subscriber you
dialed is out of the service zone" or "The subscriber
you dialed is not able to answer your call, please try
again later." This is because your mobile phone
cannot access the network with both SIM cards at
the same time and has nothing to do with your
service provider's network condition. It is
recommended that you subscribe to services such
as voicemail or missed-call reminders from your
service provider to avoid the inconvenience caused
by missed calls.

When you are using one SIM card's data services, you can
receive calls and messages using the other SIM card, but
data services will be interrupted.
For example, when SIM card 1's data services are in
use, you can use SIM card 2 for calling and
messaging, but SIM card 1's data services will be
interrupted as a result. When the call using SIM
card 2 is terminated, or the message is received or
sent, you can resume using SIM card 1's data
services.
