provider.
1. Insert your fingernail into the slot at the bottom left of the back
cover and lift it up gently.
2. Hold the nano-SIM card with the cut corner oriented as shown

15

removing it (see Using the microSDHC Card as Portable
Storage).
1. Remove the back cover.
2. Hold your microSDHC card with the metal contacts facing
down and slide it in.

17
NOTE:
Some applications may require a microSDHC card to work
normally or may store certain data on it. Therefore, it is
recommended that you keep a microSDHC card installed and
not remove or replace it randomly.
3. Replace the back cover.
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.
If the battery is low, there will be a pop-up message on the
screen. As you char ge your phone, the screen will tell you the
exact battery level each time you wake up your phone.
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/micro-USB jack. Ensure
that the adapter is inserted with the correct orientation. Do not

the phone even when it is being charged. In this case, try again
after charging the phone for at least 30 minutes. Contact the
customer service if you still cannot power on the phone after

19
prolonged charging.
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 Wi-Fi, Bluetooth and auto-sync off when not in use.

using this function will periodically query the GPS satellites
for your current location, and each query drains your battery.
Use the battery saver feature.
