Upgrading the Phone Software
There are several ways to upgrade your phone software:
1. Use the online upgrade tool for mobile terminal products.
2. Use the one-press upgrade package offered by your mobile service provider.
3. Use your PC to download an upgrade package to your microSDXC card and install it
to your phone from the card.
NOTE:
Visit the ZTE official handset service support website
Z-Community
(https://community.zteusa.com) to learn more about the above upgrade methods, as
well as which phones and methods are supported.
Troubleshooting
If you encounter problems while using the phone, or if it performs abnormally, you
can refer to the chart below. If your particular problem cannot be resolved using the
information in the chart, contact the dealer where you purchased the phone.
Problem
Possible Causes
Possible Solution
Poor reception
The network signal is too weak
at your current location (for
example, in a basement or near
a tall building) because wireless
transmissions cannot effectively
reach it.
Move to a location where the
network signal can be properly
received.
The network is busy at the
current time (for example, during
peak times, there may be too
much network traffic to handle
additional calls).
Avoid using the phone at such
times, or try again after waiting
a short time.
You are too far away from a base
station for your service provider.
You can request a service area
map from your service provider.
Echo or noise
Poor network link quality on the
part of your service provider.
End the call and dial again.
You may be switched to a
better-quality network link or
phone line.
Poor local telephone line quality.
End the call and dial again.
You may be switched to a
better-quality network link or
phone line.
