Introduction
The NETGEAR 4G LTE Modem LM1200, 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 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 that came with
the device, and 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 View APN Profiles or
Add a Custom APN Profile on page 22.
