# Dealing with network issues

Mobile networks are constantly evolving and providing faster data connection speeds between the device and the network. The faster the connection, the less time it takes to transfer Web content. Third generation (3G) networks deliver the speed for browsing the Web smoothly, and the latest advancements (HSDPA, or High-Speed Downlink Packet Access) bring the bandwidth of a fixed Internet connection to the mobile. The data pricing models are changing toward flat-rate data plans for unlimited data transfer. In addition, more and more devices support WLAN and public Wi-Fi hotspots.

Even with these improvements, you should consider the following issues:

- Network connection costs

  If users do not have a flat-rate data plan or WLAN support, mobile network connections cost them money. Keep the user informed when establishing connections from your widget, for example, by displaying pop-up views on the screen. Allow users to turn off the pop-up views.

- Network connection breaks

  Mobile devices are constantly moving, which causes changes in the network availability. Data connections may suddenly be lost for a shorter or longer period; for example, due to bad radio coverage.

You can use network information services to check the network signal strength, name, and registration status. For more information, see Network information services.
