To access the Internet and to send multimedia messages, you must have a mobile data connection and the correct settings, also known as APN (Access Point Name) settings. The APN identifies the network that a mobile device can connect to.
You can usually download Internet and messaging settings when you set up your device for the first time with a SIM card inserted. In other cases, the settings may be pre-installed. If not, you can download or add the settings manually. Contact your network operator for detailed information about Internet and messaging settings.
|If you cannot access the Internet, have no data connection, or cannot send or receive multimedia messages, try deleting all Internet and messaging settings and then add them again.|
An APN is used to establish data connections between your device and the Internet. The APN defines which type of IP address to use, which security methods to invoke, and which fixed-end connections to use. Checking the APN is useful when you cannot access the Internet, have no data connection, or cannot send or receive multimedia messages.
|If you have several available connections, the active network connection is indicated by a marked button.|
