You could be facing one of several issues. First you need make sure that wireless data is a part of your contract, and if it is, then make sure you have the phone’s 3G capabilities turned on. Also, you will need a minimum of two bars of signal for the browser to work on the LG CU400. If all of that is set then you may need to clear your cache and cookies because your phone won’t be able to access any data if it has nowhere to store it. I recommend visiting [[LG CU400 Troubleshooting]] for specific instructions.
