How do I configure a 3G interface on an AR router

When WCDMA is used, the procedure for configuring a 3G interface is as follows:
[Huawei] apn profile 3gprofile //Create an APN profile.
[Huawei-apn-profile-3gprofile] apn 3GNET
[Huawei-apn-profile-3gprofile] user name 3guser password cipher Password@123 authentication-mode auto
[Huawei-apn-profile-3gprofile] quit
[Huawei] dialer-rule //Configure a dialer ACL.
[Huawei-dialer-rule] dialer-rule 1 ip permit
[Huawei-dialer-rule] quit
[Huawei] interface cellular 0/0/0
[Huawei-Cellular0/0/0] link-protocol ppp
[Huawei-Cellular0/0/0] ip address ppp-negotiate //Configure an IP address through PPP negotiation.
[Huawei-Cellular0/0/0] ppp ipcp dns request //Configure a DNS server address through PPP negotiation.
[Huawei-Cellular0/0/0] dialer enable-circular //Enable C-DCC.
[Huawei-Cellular0/0/0] dialer-group 1 //Associate Cellular0/0/0 to the dialer access group.
[Huawei-Cellular0/0/0] dialer number *99# //Configure a dialer number for calling the remote end.
[Huawei-Cellular0/0/0] mode wcdma wcdma-precedence //Configure a network connection mode.
[Huawei-Cellular0/0/0] apn-profile 3gprofile //Bind the APN profile to the 3G cellular interface.
[Huawei-Cellular0/0/0] shutdown
[Huawei-Cellular0/0/0] undo shutdown
[Huawei-Cellular0/0/0] quit

When CDMA2000 is used, the procedure for configuring a 3G interface is as follows:
[Huawei] dialer-rule //Configure a dialer ACL.
[Huawei-dialer-rule] dialer-rule 1 ip permit
[Huawei-dialer-rule] quit
[Huawei] interface cellular 0/0/0
[Huawei-Cellular0/0/0] link-protocol ppp
[Huawei-Cellular0/0/0] ip address ppp-negotiate //Configure an IP address through PPP negotiation.
[Huawei-Cellular0/0/0] ppp ipcp dns request //Configure a DNS server address through PPP negotiation.
[Huawei-Cellular0/0/0] dialer enable-circular //Enable C-DCC.
[Huawei-Cellular0/0/0] dialer-group 1 //Associate Cellular0/0/0 to the dialer access group.
[Huawei-Cellular0/0/0] dialer number #777 //Configure a dialer number for calling the remote end.
[Huawei-Cellular0/0/0] mode cdma hybrid //Configure a network reconnection mode.
[Huawei-Cellular0/0/0] quit
