Support IoT card industrial three-proof tablet computer analysis
Higole 4G full Netcom three-proof tablet computer supports IoT cards and is used in many uses in various industries. It is a very practical and small-sized handheld tablet (8 inches and 10 inches), but in practical applications, many people do not know the relationship between the IoT card and the SIM. The following is a brief introduction Let's take a look at the differences and commonalities between the two, as well as their advantages and disadvantages.
1. The materials are different. The plug-in IoT card and the ordinary SIM card are the same in size, size and shape, but the ordinary SIM card is used in the environment of the mobile phone, and the relative temperature and humidity are ideal, and the materials such as PVC and ABS are generally used for packaging; As the IoT card is to be used in Internet of Things devices, and some are also used outdoors, where it is exposed to wind, sun and rain, the material used is stronger than that of ordinary SIM cards.
2. The ordinary SIM card is mainly a plug-in MP card, but the IoT card adds an embedded MS card, which adopts a welding process and is pre-installed in the IoT device. It has good shock resistance and ensures stable data transmission.
3. Ordinary SIM cards do not need a management platform, but IoT cards generally require an IoT card management platform. On the platform, you can check traffic usage, whether the device is online, recharge and other functions.
4. Common SIM cards have built-in STK menus, through which you can use a function or application; the IoT card is mainly used for Internet access, and has no other applications.
Based on the above four points of analysis, we can roughly understand that the IoT card contains the functions of the ordinary SIM card, and the algorithm has been upgraded in terms of security to support the two-way authentication between the card and the network, and it has a larger capacity and processing capacity. It provides hardware support and related support platform management for the needs of the Internet of Things industry. Therefore, many enterprises and government units currently require support for IoT cards and handheld three-proof tablet computers.
