In the era of rapid development of the communications industry, 4G networks have been generally operating, affecting people's clothing, food, transportation and other aspects. Such as smart grid, smart transportation, smart home, finance, mobile POS terminal, supply chain automation, industrial automation, smart building, fire protection, public safety, environmental protection, meteorology, digital medical treatment, remote sensing survey, military, space exploration, agriculture, forestry , Water, coal, petrochemical and other fields. When it comes to these areas it is inseparable from industrial routers. In the face of high temperature, extreme cold and other complex working environments, how can we achieve high-speed and stable network deployment of industrial equipment? Faced with increasing operating demands, dual card routers have emerged.

Dual SIM 4G router, as the name implies, there are 2 SIM cards available for routers. When there is a blind spot, fluctuation, or interruption in one operator's network, it can quickly and automatically switch to another operator's network to ensure stable and smooth communication. Why do dual sim 4g routers work without sleep for 24 hours?

Dual Sim 4g router has 5 working modes. You can use one of the cards, or you can use dual cards at the same time to achieve dual-network real-time online.
1.Only SIM card 1 is available
2.Only SIM card 2 can be used
3. SIM card 1 has priority. If SIM card 1 goes offline, it will switch to SIM card 2. After recovering SIM card 1, switch to SIM card 1
4. SIM card 2 has priority. If SIM card 2 is offline, it will switch to SIM card 1. After recovering SIM card 2, switch to SIM card 2
5. Automatic: SIM card 1 continues to work until it is intelligently turned off to SIM card 2, and then continues to work on SIM card 2 until it is intelligently turned off to SIM card 1.

Why do many people like to use dual SIM 4G routers? The dual-card 4g router has a dual-mode dual-card design. The dual-operator network is online in real time. Users can use the dual-card 4G router to perform outdoor networking work more efficiently. The product can ensure that dual-mode or different operators can only switch online and multi-network modes at the same time, to ensure that communication links are switched and backed up to prevent dropped calls; not only can it be switched between wired and wireless at any time, but it also supports VPN private networks to meet the full Netcom mode The need for high-speed networking.
