Set up APN for 3G Service

mobile phone network. It is a network identifier used by a mobile device when connecting to a 3G carrier. The
carrier will then examine this identifier to determine what type of network connection should be created.
For uploading the data to a web server, a set of 3G APN from your 3G network is required. Various 3G network

password of APN are indefinite or showed in blank, just leave the parameters empty (no space). User can follow
