The NETGEAR LB2120 4G LTE Modem is a compact, lightweight unit that will plug directly into your existing router or computer to give you instant 4G LTE connectivity at up to 150 Mbps downstream and 50 Mbps upstream. Actual speed varies by wireless network and region.

The LB2120 works out of the box with all GSM carriers, including AT&T and T-Mobile networks, though the device will not work with Verizon or Sprint.

The unit has two gigabit ethernet ports for high-speed WAN/LAN connectivity, and has two TS-9 ports for attaching optional antennas to improve signal strength and performance.

The NETGEAR LB2120 4G LTE Modem is a reliable backup source when your wired broadband connection is not available. Its compact design and low power consumption also makes it ideal for business on the go. The device is fully compatible with all major operating systems running TCP/IP and most modern web browsers, which are needed only to access the internal device configuration user interface.

I personally use an LB2120 as my primary internet source, and have been fully satisfied with its performance. Right out of the box, I took the modem down to my local T-Mobile store to get a SIM card, which they were more than happy to supply and install for me. When I took it home and plugged it into my router, it took mere seconds for the computers on my network to detect and configure the new Internet connection, and I was online. It was that simple.

This item is available from all major online retailers, such as Amazon and Ebay.
