SR510 2 Port 5G Router

As technology and the economy rapidly develop, the Internet of Things (IoT) is increasingly being applied to hardware devices across various industries, with smart industries like smart manufacturing being among the most prominent users. Devices such as industrial routers, sensors, and data collectors in smart manufacturing are common IoT-enabled hardware. However, those unfamiliar with the IoT industry might wonder what kind of SIM card is suitable for industrial plug-in routers. Below, we will address this question.

What is an IoT SIM Card?

IoT SIM cards, also known as IoT cards or SIM cards, are provided by mobile, telecom, and联通 operators and support 2G/3G/4G/5G networks. Consumer-grade cards look similar to regular SIM cards but use a dedicated number range to meet the needs of smart hardware and the IoT industry for device connectivity. Industrial-grade cards come in two forms: regular cards and SMD (Surface Mount Device) cards.

What Kind of SIM Card is Suitable for 5G/4G Industrial Plug-in Routers?

1. Regular SIM Traffic Cards: These are the same as the daily-use mobile phone cards and are commonly used in scenarios with fewer industrial routers. The main drawback is the high cost of regular SIM card traffic, coupled with the large number of devices and high traffic consumption required by industrial routers. Therefore, this method is not widely accepted.
2. IoT SIM Cards: Commonly used in smart homes and industrial networking, these are specially designed for enterprise hardware devices by the three major operators and are prohibited for personal mobile phones and tablets. They feature “large traffic and low cost,” making them the best choice for industrial router networking.
3. VPDN Dedicated Network Cards: These are a type of IoT SIM card that provides dedicated IP addresses or application-specific traffic cards, offering high security and stability.
4. APN Dedicated Network Cards: Also a type of IoT SIM card, these require parameter configuration before accessing the internet. These parameters determine the access method for accessing the mobile network.

Key Considerations When Purchasing IoT SIM Cards

1. Stability and Reliability:
   For industrial and commercial sectors, stability and reliability are paramount. When purchasing a 4G plug-in router, look for products with high stability and reliability. High-quality brands like Huawei, ZTE, and Cisco offer high-performance, robustly designed routers specifically for industrial and commercial use. These products typically have higher performance, stronger protection measures, and greater reliability and stability.
2. Supported Frequency Bands:
   The frequency bands supported by 5G/4G plug-in routers are also a crucial consideration. Before purchasing, ensure that the router supports the frequency bands in your region. If the router does not support the local frequency bands, signal instability will occur, affecting usage.
3. Line Interfaces:
   When choosing a 5G/4G plug-in router, ensure its line interfaces are compatible with your company’s existing network architecture. Consider factors such as the number of LAN ports needed, whether one WAN port is sufficient, or if multiple WAN ports are required. Additionally, consider whether other interfaces like serial ports and digital I/O interfaces are needed for interoperability with other hardware.
4. Data Security:
   Data security is extremely important for industrial and commercial 4G plug-in routers. Ensure the router supports advanced security features like VPN or IPSEC connections. These encryption technologies protect devices and data from hackers and other security threats, ensuring full protection during transmission and processing.
5. Shock Resistance:
   For routers used in industrial environments, they must be able to withstand shocks, vibrations, and impacts. Industrial environments often have adverse factors like vibration, high temperatures, high humidity, and strong electromagnetic interference. Therefore, when purchasing a 4G plug-in router, pay attention to its shock resistance indicators to ensure stable operation in harsh conditions.

In summary, when purchasing industrial-grade 5G/4G plug-in routers, consider factors such as stability and reliability, supported frequency bands, line interfaces, data security, and shock resistance. Choosing high-quality, technologically advanced routers with advanced features can effectively improve production efficiency and ensure production safety.
