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.
