Configuring a 3G/4G network
Restrictions and guidelines
Both 3G and 4G modems can access GSM, CDMA2000, TD-SCDMA, and WCDMA networks. Only
4G modems can access LTE networks.
A 3G/4G modem is used to search a public land mobile network (PLMN) for accessible mobile
networks. A PLMN is uniquely identified by the mobile country code (MCC) and the mobile network
code (MNC). Some 3G/4G modems can automatically access a mobile network. To manually specify
a mobile network for a 3G modem, first search for available mobile networks.
