1. Advantages of 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. E-Lins’ H900 is a typical
dual sim 4g router.
Providing 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 and flexibility 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.
Bringing more fast speed
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 Mbps and 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.

2. 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.
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.
