What is an IoT card?
The IoT card refers to information sensing devices such as radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners, etc., and connects any items to the Internet for information exchange and communication according to a contractual agreement. A network that intelligently identifies, locates, tracks, monitors, and manages. Simply speaking, the communication IoT card is a smart device (mobile terminal, in-vehicle device, etc.) that uses a certain scenario to link people, resources (resources), and services through a communication transmission network, thereby efficiently achieving a specific requirement. It is a mobile communication access service provided by operators for Internet of Things users based on the Internet of Things public service network. The three major operators use their own IoT dedicated number segments to support basic communication services including SMS, wireless data and voice through dedicated network element devices, and provide intelligent connection services such as user-independent communication connection management and terminal management.
IoT cards are divided into MS cards and MP cards. Under normal circumstances, MS cards are only used for production front loading, while MP cards are available for front and rear loading. Due to its small size, shock resistance, high temperature resistance and long life, MS cards are often used in car front loading, smart meter reading and wearable devices, while MP cards are more widely used due to their low cost and easy installation.

The IoT card is simply a pure traffic card. In fact, it can make calls and send and receive text messages. However, because the cost of calling and sending and receiving information is not cost-effective, it is only a pure traffic card. The shape is sim. Similar to the card, the traffic tariff is more cost-effective, and it is applied in mobile payment, Pos machine, smart wear, and car networking.

Select supplier:
There are a large number of suppliers in the market. How to choose a long-term stable and reliable supplier from many suppliers requires you to judge according to the actual situation. Card merchants use cards as commodities and sell cards in the form of trade, pursuing short-term commercial activities. Shopping Lianca is essentially a purchase service. Only by making the service a good job, the user can provide operational support for long-term use of traffic through a powerful platform, so that users can use the IoC card with peace of mind.
