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.
