Dual-Card Dual-Standby
Your mobile phone supports dual-card dual-standby
mode, which can significantly reduce power
consumption and increase your phone's standby time.
Note that two restrictions 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.
