Installing the nano-SIM Card (Included)
Power off your phone before installing and removing the
nano-SIM card.
NOTE: Your phone will come with the nano-SIM
card already installed.

non-standard nano-SIM card cut from a SIM
card. You can get a standard nano-SIM card
from your service provider.
1. Insert your fingernail into the
bottom left corner of the back
cover and lift it up gently.
2. Hold the nano-SIM card with the cut
corner oriented as shown and slip
them into the card slot.

12
Installing the Battery and
a microSDHC™ Card (Not

Power off your phone before installing and
removing the battery. You have the option to

expand your phone's storage capacity.
The microSDHC card can be installed and
removed while the phone is turned on.
Unmount the microSDHC card before
removing it.
1. Insert your fingernail into the bottom
left corner of the back cover and lift it
up gently.
2. Insert the battery by aligning the metal contacts on the battery
with the metal contacts in the battery compartment. Gently
push down on the battery until it clicks into place.
WARNING! Do not handle a damaged
or leaking Li-lon battery as you can be
burned.
3. Hold your microSDHC card with the metal
contacts facing down and slide it into the
card slot.

13
NOTE: Some applications may require a microSDHC card to
store certain data on it and to work properly. Therefore, it is
recommended that you keep a microSDHC card installed and
not remove or replace it unnecessarily.
Charging the Battery
Your phone’s battery should have enough power for the phone to
turn on, find a signal, and make a few calls. You should fully
charge the battery as soon as possible.
Do not change the built-in rechargeable battery in your phone by
yourself. The battery can only be changed by ZTE or ZTE
authorized service provider.
WARNING! Use only ZTE-approved chargers and cables. The
use of unapproved accessories could damage your phone or
cause the battery to explode.
1. Connect the adapter to the charging
port.
2. Connect the charger to a standard
AC power outlet. If the phone is on,
you’ll see a charging icon, such as
or , appear on the status bar.
3. Disconnect the charger when the
battery is fully charged.
NOTE: If the battery is extremely low, you may be unable to
power on the phone even when it is being charged. Contact
customer service if you still cannot power on the phone after
prolonged charging.

14
Extending the Battery Life
Active applications, screen brightness levels, Bluetooth and Wi-Fi
usage and GPS functionality can drain your battery. You can
follow the helpful tips below to conserve your battery power:
Reduce the screen backlight time.
Lower the screen brightness.
Turn auto-sync, Wi-Fi, and Bluetooth off when not in use.
Disable the GPS function when not in use. Most applications
using this function will periodically query the GPS satellites
for your current location; each query drains your battery.
Powering Your Phone On/Off
Press and hold the Power/Lock Key to turn on your phone.
To power it off, press and hold the Power/Lock Key to open
the options menu. Tap Power off >OK.
NOTE: If the phone freezes or takes too long to respond, press
and hold the Power/Lock Key for about 10 seconds to restart
your phone.
Setting Up for the First Time
When you first power on your phone after you purchase it or
reset it to factory settings (see Settings –Personal –Backup &
Reset), you may need to set it up before using it.

15

the phone into sleep mode) when not in use and to turn the
screen back on and unlock it when you need it.
Locking the Screen and Keys:

Power/Lock Key.
NOTE: To save battery power, the phone automatically turns off
the screen after some time of inactivity. You will still be able to
receive messages and calls while the phone screen is off.
Unlocking the screen and keys:
1. Press the Power/Lock Key to turn the screen on.
2. Press and hold a blank area of the screen to unlock the
