WiFi modem compatible with three SIM cards for 4G LTE connectivity
I had three 4G LTE connections at home, each from a different provider. I usually use them individually since each has its own Wi-Fi hotspot. I wondered if it’s possible to combine all three SIMs into one device to boost speeds to three times the 4G rate. This could work with any of your Wi-Fi routers to broadcast as Wi-Fi. I see an benefit here because using three different providers would reduce the chances of internet outages or speed drops. Anyone have ideas, products, or DIY tips for this setup?
It doesn't quite work that way. Three internet connections give you three distinct IP addresses. What you can actually do is switch to failover and load balancing. In practice, this isn't a speed boost—it just means using more bandwidth. You won't find routers with three SIM slots; however, if you locate a standard 4G modem and purchase three of them, you might be able to assemble a router that supports three WAN connections. There are some that can handle two, but you won't see significant speed improvements. The only known option for true three-WAN support is PF-Sense.
Donut417 discussed load balancing with three WAN connections on pfSense. A 4G modem would likely be necessary, possibly through a router from each service provider or by purchasing new ones. Load balancing improves performance for tasks like multi-threaded torrents or simultaneous file downloads. More details are available at the provided link.
Ubiquiti Edgerouter Series supports this too. However, to achieve a single faster connection after Viprinet and Peplink, you’ll need a bonding provider.
