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 dialled is out of the
service area" or "The subscriber you dialled cannot
be connected for the moment, please try again
later."
•
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 may help to contact your service provider and
subscribe to missed call reminder and related assistance
services to ensure you never miss a thing.
