Pass (dual-SIM devices only)
Your device supports only dual card dual standby single pass,
which means you cannot use both SIM cards for calls or data
services simultaneously.
l 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.
l When you are using SIM card 1's data service, SIM card 2's
data service will be disabled.
Your device's single pass feature helps reduce power
consumption and increase your device's standby time. It is not
related to your service provider's network conditions.
l Dual-SIM 4G network usage requires the support of
your carrier's network and the deployment of relevant
services. Some services may be unavailable due to the
carrier's network conguration. Available software
functions are subject to change with the subsequent
updates of your network and system version. If this
