What to do if my Zte Z837VL Cell Phone has poor reception?
If your Zte Cell Phone has poor reception, it could be due to a weak network signal at your location. Try moving to a location where the network signal can be properly received. The network might also be busy. Avoid using the phone at peak times, or try again after a short wait. If you are too far from a base station, request a service area map from your provider.

Why am I unable to select certain features on my Zte Cell Phone?
If you are unable to select certain features on your Zte Cell Phone, your service provider may not support these features, or you may not have applied for the services that provide these features, so contact them. It can also be caused by the damaged battery or battery charger, in this case you should contact the dealer. The phone’s temperature being below 0 °C or higher than 45 °C can be the reason, so adjust the battery charging environment to avoid extremes of temperature.
