Notice
We offer self-service for our smart terminal
device users. Please visit ZTE ofcial website
(at www.zte.com.cn) for more information on
self-service and supported product models.
This product is designed to support two SIM
cards. You can install two SIM cards simul-
taneously and have them both in standby.
However, both SIM cards cannot be used
at the same time for phone service or data
service. When you're in a phone call using
one SIM card, the other one will be unreach-
able through phone call. Callers to that card's
number may hear voice prompts such as
"The number you dialed is unreachable."
or "The number you dialed is out of service
area".
The above situation is caused by the phone
design and has nothing to do with the network
of your operator. This design can signicantly
reduce power consumption and improve your
phone's standby time. In case of missing
important phone calls, please contact your
operator to enable services like missed call
alerts.
