Introduction
The NETGEAR LTE Modem LB1120 and LB1121 models, in this manual referred to as the modem, can
provide broadband data services to areas where wired Internet is not readily available or is difficult, costly,
or time-consuming to install. The modem uses existing 4G LTE mobile networks with automatic fallback to
3G mobile networks to provide broadband data services.
If you connect a WiFi router to the modem's Gigabit Ethernet port, the mobile network connection can provide
high-speed Internet access for multiple users and devices in homes and offices.
Alternatively, you can connect the modem to an existing DSL, cable, or fiber optics gateway that supplies
two WAN ports so that the modem can provide a backup Internet connection for your home or office to
achieve continuous connectivity.
Professional installation and configuration are not required. If a SIM card is installed and activated, by default,
the modem automatically searches for and connects to your network provider's mobile broadband network.
For information about installing the modem, see the quick start guide, which you can download from
downloadcenter.netgear.com.
In the unlikely situation that the modem does not automatically connect to your network provider's mobile
broadband network, you might need to add an access profile name (APN) profile. For information about
adding an APN profile, see
