The E-Lins H700 series dual sim lte router is a compact, ruggedized 3G/4G/LTE, Gigabit Ethernets and Dual Band Wi-Fi (2.4Ghz + 5Ghz) networking solution designed for mission-critical connectivity in the most challenging environments. It is qualified for M2M (Machine to Machine), IoT (Internet of Things) and In-Vehicle applications.
With an extensive list of safety and hardening certifications, the H700 4G dual sim lte router is engineered to protect against extreme temperatures, humidity, shocks, vibrations, dust, reverse polarity, and transient voltage, which is widely used in more than twenty industrial fields, such as CCTV security surveillance, vehicle, Telemetry, vending machines, power control, AMR, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other areas.

To further enhance the wireless M2M and IoT reliability, the H700 has a second SIM Card slot so that you can insert two SIM cards to get different applications.
1) Failover
With this using, usually you can get two SIM Cards from different mobile network. One is the primary SIM, the other is backup SIM. In the event that the primary network becomes unavailable then the router will switch to the backup SIM card and use the alternative service provider.
2) Load Balancing and Link Bonding
Being a 3G/4G Load Balancing Router, the H700 can utilise the two embedded 4G modules, the RJ45 WAN and WiFi Client connections all at the same time and share these WAN connections with the LAN users.
With channel link bonding, the H700 4G router makes two or more links are combined for redundancy or increased throughput. Channel bonding is differentiated from load balancing in that load balancing divides traffic between network interfaces on per network socket (OSI model layer 4) basis, while channel bonding implies a division of traffic between physical interfaces at a lower level, either per packet (OSI model Layer 3) or a data link (OSI model Layer 2) basis.
H700 4G LTE router is Industrial designed, excellent function to ensure 7x24h running in stability and reliability;
Wide range power input with dual types of input supported; Alloy-metal case, IP30 protection standard;
Quality industrial grade casing provides robust and reliable 4G router for installation in many different environments and operating temperature of -35 Celcius to +75 Celcius.
The H700 4G Bonding router can built-in single modem or dual modem for failover, load balancing and bonding applications. With two modems, the H700 4G dual SIM LTE router can switch from main SIM card to backup SIM card without delaying to meet the reliable applications.
The H700 built-in 2.4GHz + 5GHz dual band or tri band WiFi with concurrent data transmission to achieve high powerful WiFi performance.
Offer more VPN safety application schemes, data transmission reach to financial grade standard. E-Lins wireless routers support APN/VPDN private networks, also including various VPN access such as IPSEC, PPTP, L2TP, GRE,OPENVPN, DMVPN, etc. including the function of VPN client and server. Add one more channel of encryption communication under the base of special network can fully guarantee the safety and accuracy of data of dealing and management.
The H700 Dual SIM 4G Router supports wide voltage range of 5V to 40V DC (option up to 60V DC) and has two power inputs so if the primary power fails then the modem will automatically use the second power supply without link downtime.
Supporting Web GUI, Telnet SSH Command, SMS, TR-069, SNMP, and NMS (E-Lins Network Management System), users can manage and control the H700 easily and flexibly.All E-Lins communication terminals can be connected to the E-Lins remote managing and controlling platform (NMS), which brings the generous devices scattering in different areas to carry out concentrate monitor, configuration, updated, diagnose, maintenance, manage and control. Highly reduce the maintenance costing in the operator, integrator, devise supplier etc, increase the managing efficiency.

= field-tested on live networks. The H685T uses TDD-LTE bands — verify your carrier's band plan (B38/39/40/41) before ordering; FDD regions are served by the H820 series.
Standard H685T units are not ATEX-rated. For oil & gas, mining and chemical sites in Zone 1 / Zone 2 hazardous areas, E-Lins offers certified enclosure packages and intrinsic-safety consultation through OEM projects. Contact our engineering team with your zone classification for a compliant configuration.

The H685T supports TDD-LTE Band 38 (2600 MHz), Band 39 (1900 MHz), Band 40 (2300 MHz) and Band 41 (2500/2600 MHz), with fallback to TD-SCDMA (2010–2025 / 1880–1920 MHz) and EDGE/GPRS/GSM quad-band (850/900/1800/1900 MHz). Other TDD-LTE band combinations are available on request — see the datasheet for the full band list.
Yes — the H685T is carrier-unlocked and accepts any standard SIM/UIM card. APN is auto-detected for most carriers. Before ordering, confirm your carrier operates TDD-LTE Bands 38/39/40/41; for FDD-LTE regions (most of Europe / the Americas), choose the H820 series instead.
Yes. With the RS232 or RS485 option (H685T-S / H685T-S485), the router works as a serial-to-cellular DTU gateway, transparently tunneling Modbus RTU traffic from meters, PLCs and RTUs to your SCADA center over TCP/UDP. Configuration takes minutes in the Web UI.
Insert an activated SIM, connect power (5–40 V DC — 12 V / 24 V cabinet and vehicle supplies work directly), attach the antenna, and the router registers on the network within about a minute. Default Web UI is at 192.168.8.1; APN, failover and VPN are configured in a guided flow. Most sites go from unboxing to online in under 10 minutes.
Yes — the compact metal enclosure is designed for street cabinets, pole boxes and control panels, with a −35 °C to +75 °C wide-temperature design and enhanced ventilation. Wall-mount and DIN-rail kits are available as accessories; the Hardware Installation Guide covers grounding and wiring.
Yes. The H685T supports three-way failover between 4G/3G/2G cellular, wired WAN (xDSL via RJ45) and Wi-Fi client mode. You can choose cellular-preferred or WAN-preferred backup strategies, and a built-in watchdog automatically restarts the link if the connection drops — an always-online design.
Yes — a full VPN suite: PPTP, L2TP, IPsec and GRE, with IPsec PKI digital certificates and extended authentication for compatibility with third-party VPN concentrators. IP/MAC filtering and an SPI firewall protect against DoS attacks.
All E-Lins routers integrate with the E-Lins NMS cloud network management system — remote monitoring, bulk configuration, firmware upgrades and alerts. SNMP (MIB-II + private MIB), Telnet, SSH2, Web UI and SMS status control are also built in. Learn about NMS →
Yes — firmware updates run over the Web UI, via the Configuration Tool over LAN, or in bulk through E-Lins NMS for entire fleets. Dual-image fallback means a failed update never bricks a remote unit; the step-by-step procedure is documented on the Wiki ("H685T Firmware Update Procedure").
Every H685T carries a 5-year limited hardware warranty, a 30-day return policy on standard units, and lifetime firmware updates. Extended warranty and advance-replacement SLAs are available for volume and OEM projects.
Yes. E-Lins has provided OEM/ODM services since 1999: custom firmware, branding, enclosure and feature options (RS232/RS485, GPS, SMS/voice control, RIP/OSPF/BGP, PoE). Evaluation customization starts from a single unit; production branding typically starts at 50 units.
Standard models have no MOQ — order one sample to validate your application. Standard lead time is 2–4 weeks depending on options and quantity; volume pricing starts at 10 units, OEM pricing at 50+. Request a quote and receive a formal offer within 4 business hours.
