No Network Connection

• If the Samsung E900's screen displays the message "Network failure," "No service," or "Not done," it is an indication that the phone does not have a connection to a cellular network. Without a network connection, you will be unable to make and receive calls with the E900 or access its other features. One potential cause for this problem is that you are in a weak signal area. To regain a network connection, move to a different area. Alternatively, you may not have subscribed to the specific network options you are trying to access, in which case you should contact your cellular service provider.
