What is an IoT card?

The Internet of Things card is a 4G/3G/2G card provided by operators (China Mobile, China Unicom, China Telecom). The hardware and appearance are similar to a regular SIM card. It is loaded with specialized functions for smart hardware and IoT devices, and adopts dedicated number segments and numbers to meet the management needs of the smart hardware and IoT industries for device networking, as well as the mobile information application needs of group companies and chain enterprises.

What are the functions of the IoT card? Let’s take a look below:

The IoT card satisfies users’ requirements for low power consumption/long standby, deep coverage, large capacity, etc. Rate business requirements can be applied to scenarios such as static services with poor mobility or discontinuous movement, real-time data transmission, etc.

1. Basic communications, GRPS communication capabilities and SMS communication capabilities, fully meet the needs of customers in different groups.

2. Financial information query, provide account information to customers, and provide reminder functions for account arrears, traffic exceeding standards and other events.

3. Terminal status query, providing customers with information queries such as power on and off information, terminal location information, terminal GPRS online, offline, IP, APN and other information. 4. Business statistical analysis

4. Business statistical analysis provides users with multi-dimensional business report statistics and analysis.

Why are IoT cards so cheap? Let’s take a closer look:

The traffic packages of IoT cards include a shared traffic pool and an independent package. Packages are divided into monthly packages, quarterly packages, annual packages, etc.

Introduction to the Internet of Things Card Center: The Internet of Things card is an independent management system, which is different from ordinary mobile phone cards. Therefore, operations such as recharging, overlaying, and checking traffic cannot be realized through customers and business halls. When purchasing For IoT cards, agents must either provide an IoT card management system or APP, or the company’s qualifications must be examined.

When it comes to IoT cards, we have to talk about the issue of traffic pools. At present, general operators open a "traffic pool" for each enterprise after selling IoT cards to enterprises. , the size of the traffic pool is directly proportional to the number of cards you take and the monthly traffic of a single card. The IoT cards owned by the enterprise consume the traffic in the "traffic pool" during use. Operators can manage, control, and even locate IoT cards through the backend. Once the traffic in the "traffic pool" is exhausted and the enterprise fails to renew in time, the operator will make the IoT card unable to connect to the Internet through backend management. Currently, because The Internet of Things industry is becoming more and more popular. Many unscrupulous agents and companies will sell cards from traffic pools to individuals for use, because they use traffic pools, and then use deductions to quickly reduce costs. Although IoT cards are cheap, they are very fragile. , the so-called "black card" faces downtime at any time.

Moreover, after the 25th, the system settlement will directly enter the next month. It is worth reminding that you must pay in time before the 25th, because the package is not effective, the package balance is insufficient, the traffic is exceeded, etc. Problems will affect the use of the card.

In short, we must pay attention when choosing discounts, just don't be cheated.

Finally, I wish you a happy life and enjoy the package discounts.
