4g router, that routing can be turned off
Discussion
I have been doing some searching and it seems all the 4g routers are designed as hotspots with wifi built in ect. I am after a simple 4g (with sim card slot) modem. A bit of background...
I run a small company and we are moving building soon, There is no phone line yet and and the exact date of the move is not decided. The ISP says they will swap over the broadband on a certain day but i could do with getting on and setting up the network and making sure we have internet.
My plan is get a 4g router and have internet working until the fiber is moved over. Then the 4g will be a failover in case the fiber ever goes down.
The only thing i am stuck with is that i am using ubiquiti gear (dream machine pro) and this does the routing. I just need a 4g router than can be setup to not act as a router and just pass through (bridged?), and also has a RJ45 port for plugging into the router. No wifi needed.
Does anyone know of any device that will do this? sounds simple but none of devices i have looked at mention if i can turn wifi/routing off.

Heed the warning about CGNAT if it might cause you problems. Unless you pay for an expensive SIM you’re not going to get a unique “public” IP address so things like DDNS will look like it’s working but you won’t be able to make use of it because it won’t uniquely identify you. As long as you’re not planning on running externally accessible services then this isn’t a problem.
If this doesn’t worry you then you also don’t need to worry about using a router instead of a modem. The reason you want to avoid that normally is double NAT but since you’ll already be on CGNAT adding an extra layer isn’t going to hinder you further. So any 4G router with an Ethernet port can be used in theory. As long as you set the 4G router uses a different LAN address space to your main router you can present one of its LAN interfaces to your main router’s WAN interface and select the WAN connection type as Ethernet and it’ll route regular internet traffic just fine. This gives you a wider set of kit to choose from, the main benefit of which I’d say is the routers generally give you better external antennae options.
