Why sometime we need a dual sim 4g router?

In nowadays’ machine to machine filed, some applications are using single sim 4g router while some other projects requires dual sim 4g router.

Dual SIM 4G Router with Advanced VPN

The E-Lins H900 Dual SIM 4G Router is an easy-to-deploy, high performance 3G/4G router. It features a dedicated Fast Ethernet port and dual-SIM 4G LTE mobile broadband for maximum redundancy andflexibility for intense Machine to Machine applications and cases. It supports VPN include PPTP/IPSec/GRE/L2TP/OpenVPN, which are widely used in various kinds of M2M&IoT projects.

Connectivity Where You Need It Most

Easily connect to your high-speed 3G/4G LTE mobile connection with the H900 Dual SIM 4G Router, and enjoy fast downlink speeds of up to 150 Mbpsand uplink speeds up to 50 Mbps, giving you the speed you need for fast, responsive Internet access. Deploy it in a remote location to access IP cameras and systems remotely. If you need much higher UL and DL speed, H900 also can provide you CAT6/CAT9/CAT12 level’s products. Moreover H900 can support 5G soon when 5G radio is ready.

Reliable High Speed Virtual Private Networks

The H900 Dual SIM 4G Router’s integrated VPN Client and Server support almost any VPN policy. The router’s hardware engine can support and manage multiple VPN configurations. It supports IPSec, PPTP, L2TPv2, and GRE protocols in Server mode, and handles pass-through traffic as well. Advanced VPN configuration options include multiple encryption options, key management, negotiation modes, and VPN authentication using an internal user database

Wireless-to-Wireless Failover / WAN Redundancy

I think that dual sim hot failover is the key factor for users who are using a dual sim 4g router. And this feature is very impossible in some applications. The ability to connect to two carriers at the same time is the only way to provide wireless-to-wireless, or cellular-to-cellular, failover — which can be beneficial in many situations and is the only option for WAN link redundancy for in-vehicle networking. The automatic switch from one carrier to the other occurs in mere seconds. Also, both modems can be active at the same time, allowing for more bandwidth.

At locations where wired-line connectivity is available, some enterprises use dual-modem functionality to further enhance their failover by utilizing three carriers at once. For example, they might use DSL and two different cellular SIMs to provide “four-nines” connectivity.

A good performance of dustproof

Not like home type router, an industrial dual sim router should have a strong anti-dust. In a simple word, it should be robust. The industrial grade casing means the H900 dual sim 4g router provides reliable high-speed connectivity in extreme conditions. The corrosion-resistant zinc-plated steel case and wide operating temperature and humidity tolerance mean that the H900 is ready for the most demanding M2M applications in virtually any environment. Wall mounts allow the H900 to be mounted virtually anywhere for optimal connectivity. Flexible power input allows the router to be powered by any convenient power source.

This is a simple discussion of H900 dual sim 4g router, and for more info, please do not hesitate to contact with E-Lins Technology Co., Limited.
