Dual card dual standby single
pass
MHA-L29:
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.
