First, make sure that your headphones are functioning correctly by using them with other devices. If the headphones are operating correctly, then the phone could be muted, the volume could be too low, or the headphone port could be broken. You can find more details on this issue on the troubleshooting page.

The first thing you need to check is the power of the battery. A dead battery will prevent the device from turning on. Also, the battery may need to be replaced because it is no longer able to charge. The LCD display may be broken or the back-light may not be functioning and this will hinder the device from turning on. Please see the troubleshooting page for more information.

If you cannot receive or send text messages then there is an issue with the service connected to your device. This could be either a temporary issue with the network or your current location. Your phone may also be on airplane mode, which will prevent messages from sending or being received. Please visit the troubleshooting page for more information.
