Dual card dual standby single pass
Your phone supports only dual card dual standby single 
pass, which means you cannot use both SIM cards for 
calls or data services simultaneously.
•  
When you are on a call using SIM card 1, SIM card 2 
cannot be used to make or answer calls. If someone 
calls SIM card 2, the caller will hear a voice message 
similar to "The subscriber you dialed is out of the 
service area" or "The subscriber you dialed cannot be 
connected for the moment, please try again later." 
The actual message will vary by service provider.
•  
When you are using SIM card 1's data service, SIM 
card 2's data service will be disabled. 
Your phone's single pass feature helps reduce power 
consumption and increase your phone's standby time. It 
is not related to your service provider's network 
conditions.
It may be a good idea to contact your service provider 
and subscribe to missed call reminder and related 
assistance services to avoid the conflicts mentioned 
above.
