NETGEAR 4G LTE Broadband Modem (LM1200) – Use LTE as a Primary Internet Connection | Certified with AT&T, T-Mobile & Verizon

Es una porquería, la publicidad es engañosa te hace creer que este producto genera una red wifi para conectar tus dispositivos inalámbricos pero no, sólo ofrece un puerto ethernet. Es un modem 4G yo lo uso en México con un chip de axios y si funcionó, sólo tuve que añadir el APN del proveedor y funciona muy bien. Lo malo es que tienes que pagar por otro dispositivo router que genere la red WIFI y puedas conectar todos tus dispositivos de forma inalámbrica. Este modelo LM1200 no trae batería ni botón de apagado/encendido tienes que dejarlo conectado siempre a la corriente eléctrica, no lo recomiendo.

Totally plug and play. This shouldn’t be your your primary router. It’s router features are super slim and basic. You use this in bridge mode to act as modem to connect to Bell (or Rogers) 4G for cell internet when needed during an outage of your wired (fiber, dsl or cable). You want a carrier for 4G that is different than your wired ISP. It’s a fantastic hot standby and automatic failover solution if your wired internet goes down. Or your house fiber, phone line or cable line is cut. Imagine voip, wifi, TVs, security, voice assistants, alarms, house automation all working when main internet goes down. It’s a whole house internet backup solution. Super simple to setup - get a nano sim card and ask your cell data provider to unlock it and register the IEMI # of this modem and 5 mins later you are online. You configure it with a PC via an Ethernet cable to the modem. You then connect it your primary router’s spare Ethernet jacks (that you designate as wan fail over in your router setup). You need a router that has WAN failover and preferably failback like many Asus routers. Failover is about 30 seconds and automatic once your primary internet goes offline. Nothing in your house will notice the difference - no rebooting of anything or trying to hotspot to your phone in an outage. Failback on your primary router watches for your wired internet to come back online and auto switch back to avoid costly cell data charges. Failback also happens in 30 seconds or less. This modem also has sms alerts to your phone to let you know you are on backup internet and alerts when data exceeds a set threshold. This plus notifications from your 4G provider that require exception approvals protect you from surprise high cell data bills. In standby mode, a router like Asus sends no data over the lan Ethernet cable to this modem So zero data charges, means you can get a basic $10/mth standby package for 4G online backup. (It will also hunt for 3G if no 4G but those speeds aren’t really useable - so set it to hunt for 4G only). (An Asus primary router could also use this in an actIve wan load sharing mode to increase bandwidth- but that would be super expensive data charges). Speed on this for about a 2 bar reception to cell tower is 50-70 Mbs down and 15 MBs up. There are jacks for extra antennas that don’t make much of a difference unless you put the remote antenna outside. When’s it’s in failover mode, you can logon onto to the admin interface from any lan device or phone to see real time data bandwidth downloaded. Monthly testing is as simple as unplugging the wan Ethernet cable to your wired internet modem from your router.

My wife works from home 100% now. That means it's MY job to make sure she has100% uptime. Our cable is very reliable, but it does sometimes go out at the most inopportune times so I was looking for a backup to get us through a day or so if we lose wired connectivity. Enter the NETGEAR 4G LTE Broadband Modem (LM1200). Right out of the box it worked with a T-Mobile hotspot SIM that I picked up at my local store. There's no WiFi on the LM1200 which is great, because it's not what I was looking for. If you want an LTE WiFi hotspot, there are a ton of other choices out there for you. Think of the LM1200 more as a cable modem with some very rudimentary routing capabilities (which can be turned off.) We're using Ubiquiti equipment on our network at home so I needed something that would interface with that. The Unifi Dream Machine (UDM, non-pro version) doesn't offer failover capability so the LM1200 fits in perfectly by slipping in between our cable modem and the UDM router's single WAN port. When the cable goes down, the LM1200 kicks into action and seamlessly changes the connection from our cable modem to its built-in LTE modem. When the cable comes back up, it switches back. Exactly what a UDM owner wanting failover is looking for. Having said that, the LM1200 also works well with the Unifi Dream Router 7 (UDR7) that I recently installed. The UDR7 does include failover capability between its two WAN ports and takes care of the switching on its own. In this use case, you would turn off the failover function on the LM1200 and simply attach it as another modem on the UDR7's second WAN port. Of course you still have the option of letting the LM1200 do the failover for you as mentioned above and then switch that second WAN port on the UDR7 to be another LAN port. Your choice. My only gripe with the LM1200 is that it's LTE-only. Don't get me wrong, that's fine. I knew that going in so I'm not going to take away anything from its rating. But this is 2025 and it's about time for NETGEAR to have an upgraded version that has the same capabilities but using 5G. I'm pretty sure NETGEAR knows that which is why the LM1200 is being sold for a reasonably low price. I'm perfectly happy with the LM1200 while I wait for its successor.

Could not use after purchasing, installed my Sim card and the carrier LOCKED THE SIM, NOT happy about this and feel lied to

(Updated) We planned to use this cell modem seasonally so we can cancel the expensive broadband service and still monitor our climate control and cameras. The LM1300 specs are perfect for this purpose. We tried this on Google Fi for which we have great phone reception. We ordered a Google Fi sim and setup up a Google Fi APN per instructions. It would not connect even after soliciting support from both Google Fi and Netgear which confirmed Google Fi is not a supported network. We ordered a T-Mobile sim card ($10) with the minimum T-Mobile prepaid plan ($10). T-Mobile support was incredibly helpful in activating the sim, configuring the modem, and establishing our account. The connection via Ethernet cable to our laptop fired up immediately. The failover feature (cell backup when broadband not available) was configured without issues (BB modem to LM1300 and LM1300 to TP-Link WiFi router); however it failed live testing. After spending 3+- hours on the phone with Netgear support reviewing and testing various connections, nothing has worked and, I have given up. Downgrade from 5 stars to 1 star and the LM1300 is going back within the 30 day return period. One more point. Standard Netgear support is 3 months. We purchased the LM1300 with 1 year of tech support but were unsuccessful in getting Netgear to honor the extended support even after submitting Amazon purchase documentation.
