Shortened standby time. Messaging problems Unable to send or receive text messages. Unable to send or receive email. Internet problems Unable to connect to the mobile broadband networks. The duration of standby time is affected by your service provider's system configuration. The same tablet used with different service providers' systems does not have the same duration of standby time (LTE/HSPA+ only). If you are not able to connect to the network, the tablet continues to send out signals as it attempts to locate a base station. Doing this consumes battery charge and consequently shortens standby time. Possible causes Your tablet is in airplane mode with no wireless connectivity. The network signal strength is not strong enough. The Internet connection or the email setting is not configured properly. Possible causes Invalid SIM card. You are not within the network's service area. If you are located in an area where the network signal is weak, move your location to the area where the network signal is strong or temporarily turn off your tablet if needed. Change your location to one where the network is accessible, or temporarily turn off your tablet. Possible solutions Slide the status panel down and then disable Airplane mode. Try moving to a different location for better signal reception. Check your network connection, and confirm with your email service provider if your email setting has been configured correctly. Possible solutions Contact your service provider. Check the service area with your service provider. Poor signal. Your tablet is in airplane mode with no wireless connectivity. Move to an open space or if you are inside a building, move closer to a window. Slide the status panel down and then disable Airplane mode. Troubleshooting  27
