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.
