(3) Intelligent transportation mainly refers to the integration of the Internet of Things, cloud computing, big data, mobile Internet and other IT technologies on the basis of the intelligent transportation scheduling system to provide real-time traffic data services through the pooling and processing of traffic information by information technology.
Faced with the variety of IOT card companies on the market, you need to identify and screen out the stability of the IOT card company.
(1) the simplest and most direct purchase from the official channels of the three major carriers, such as China Telecom IOT card, China Unicom IOT card, China Mobile IOT card;
