NETGEAR 4G LTE Broadband Modem - Use LTE as Backup Internet Connection, Unlocked, Works with Any Mobile Network Provider (LB2120)

I ordered this as part of my Spectrum Outage Contingency Plan, since I periodically work from home and the outages seem to be happening more frequently. When configuring this unit as a backup to your home's main router, you must ensure that the port you have this modem plugged into is configured as a WAN uplink. You must also ensure you have an active SIM installed in the modem, I purchased a cheap one for data only and currently have it riding on T-Mobile's network.You must also configure the modem to act as a bridge since by default, it is configured as a router of it's own. Configuring it as a bridge allows it to handoff the WAN connectivity to your home's router. Lastly, create a dual-WAN failover and failback rule if your router allows you to. This will ensure your home's router fails over from WAN 1 to WAN 2 and fails back when WAN 1 is restored.After simulating a Spectrum outage by pulling the coax connection, my home's router failed over successfully to this modem. My speedtest came back 40 x 30 mb/s which is fine for LTE speeds. I was able to continue working from home and stream TV along with periodic cell phone usage. So in my book, if you're looking for a cellular failover for your home, this is a good modem that can do that.

UPDATE:I had disabled the internet on this device. While I was out of town, I had lost power, and when the power came back online, I guess the internet was kicked back on. It drained my prepaid card within days and NO devices. Now Im out about $100 in prepaid data. I am NOT HAPPY. DO NOT BUY THISI was very excited to setup this device as a failover WAN2 on my network. Once I got the prepaid SIM card from my carrier, I set it up and put the device in bridge mode. My router shows that it has not made any external connections over the WAN2 interface. 0 data has been streamed over the internet through this device. AND yet I have used up nearly 1GB of data in just a few hours. This is ENTIRELY unacceptable as a bridged failover device. I will be contacting NetGear customer support to see what I can do and if this is not able to be rectified I will be returning the product and looking for another LTE modem.
