Configuring an APN Profile (A Single SIM Card and A Single APN)

Configuring an APN Profile (A Single SIM Card and A Single APN)


An access point name (APN) identifies an external PDN network (for example, the Internet or IMS network) that users want to access.

You can create an APN profile to configure APN. In the scenario where a single SIM card and a single APN are available, create an APN profile and bind the profile to an LTE cellular interface so that the APN can be used to access the Internet for data communication.


  1. Create an APN profile.


    You are advised to create an APN profile to configure an APN. You are not advised to run the profile create profile-number { dynamic | static apn } command in the LTE cellular interface view to configure an APN by creating a 3G modem parameter profile.

    1. Run system-view

      The system view is displayed.

    2. Run apn profile profile-name

      An APN profile is created and the APN profile view is displayed.

      By default, no APN profile is created.

    3. Run apn apn-name

      An APN profile is configured.

      By default, no APN is configured in the APN profile. During LTE dial-up, apn profile name specifies an access point name (APN) user name.

      • APNs are provided by the carrier.
      • Generally, China Mobile provides the APN CMNET, China Telecom provides the APN CTLTE, and China Unicom provides the APN 3GNET.
      • After an APN is configured, it is permanently recorded in an LTE data card. If the APN changes, reconfigure it.

    4. (Optional) Run user name username password { cipher | simple } password [ authentication-mode { auto | pap | chap } ]

      The user name, password, and authentication mode for accessing the external PDN network are configured.

      By default, the user name, password, and authentication mode for accessing an external PDN network are not configured.

      Contact the carrier when configuring the user name, password, and authentication mode.

      • Select a proper authentication mode based on the carrier network. PAP authentication provides lower security. When you specify auto or pap to enable the device to use PAP authentication, the password is transmitted in plain text on the network. This brings potential security risks.
      • When you specify simple, the password is saved in plain text in the configuration, which brings potential security risks. You are advised to specify cipher to save the password in the cipher text.

    5. Run quit

      Return to the system view.

  2. Bind the APN profile to an LTE cellular interface.
    1. Run interface cellular interface-number

      The LTE cellular interface view is displayed.

    2. Run apn-profile profile-name [ track nqa { admin-name test-name }&<1-2> ]

      The APN profile is bound to the LTE cellular interface.

      By default, no APN profile is bound to the LTE cellular interface.

      If track nqa is specified, the device performs an NQA probe on the LTE network when the dial-up initiated through an LTE cellular interface succeeds. The device terminates the LTE link after three consecutive NQA probe failures. Additionally, you can run the dialer timer probe-interval command to set the NQA probe interval.
