Can you introduce what an IOT card is? Are there any good channels to recommend?

As the name implies, the IOT card is for "things", not for mobile phones, but it can also be plugged into mobile phones. IOT card is a 4G/3G/2G flow card provided by operators (China Mobile, China Unicom and China Telecom), which is used to meet the networking management of intelligent hardware and the mobile information application requirements of group companies. For example: * * enjoy bicycles, mobile POS machines, vending machines, smart meters and so on.

IOT cards are only sold in bulk for enterprise users, not for individual users. IOT card can't make phone calls, can't send text messages, and only focuses on surfing the Internet, so it is a traffic card. A long time ago, there were a batch of 1 1 IOT cards with the beginning of 147, which supported voice and could make phone calls, and the price was very cheap, so they were secretly sold to ordinary users by agents. Later, the operator stopped issuing 1 1 bit IOT cards. At present, IOT cards are all 13 digits, and they can only surf the Internet, not voice, and short messages are generally limited. There are two types of IOT cards: plug-in (MP card). Like the appearance of SIM card, IOT card can work in very low or very high temperature environment. According to the product grade, ordinary chips and ordinary card-based materials should be used, or special chips and special card-based materials (such as injection molding and ceramics) that can meet the special environmental requirements should be used. SMD (MS card), directly welded on the PCB of the equipment, has a smaller size (5MM*6MM) and a higher anti-vibration index.

MS cards can only be made before loading, while MP cards can be made before and after loading. Because of its small size, earthquake resistance, high temperature resistance and long service life, MS card is often used in front vehicles, smart meters, smart parking, wearable devices, etc., while MP card is widely used because of its low cost and convenient installation. IOT card has a wide range of applications, involving many types of terminal equipment. When choosing a card, we must first make clear the network standard adopted by the communication module of the equipment and the communication ability required by the product function.

IOT card fee IOT cards are used in group enterprises and related professional fields, and individual users cannot handle them in the business hall. Operators' IOT card tariffs can be divided into: global unified tariff standards, local regional tariff standards, and group customer tariff standards, among which group customer tariffs are often the most cost-effective. Because IOT cards can also be used in mobile terminals, they are often sold to ordinary users by card merchants through group customer channels. Although this card has no language and SMS function, the traffic fee is 3~4 times cheaper than that of ordinary SIM card. Nowadays, mobile phones generally support dual-card dual standby, so many ordinary users use one SIM card for normal communication and another IOT card for cheap Internet access.

However, not all demand scenarios are the way to install traffic billing. For example, NB-IOT scenarios handle low traffic and low rate scenarios. If traffic charges are adopted, the income will become very low, which will put pressure on the return on investment in network construction of operators, so charging by "number of connections" will be generated.

Because individual users can't buy IOT cards directly from operators, they can only buy them in bulk through companies. At present, the traffic cards sold by a certain treasure, a certain sound and a certain hand are all purchased by Internet of Things companies from operators in large quantities to build a traffic pool, and then customized a series of traffic packages commonly used by individual users (such as: 10 yuan, 10G, 40G in 25 yuan, and 49 yuan 100G, etc.). ), and then wholesale to agents, agents and then sold to individual users. After purchasing the flow card, users can't recharge it through operators or other channels, but only through the system of the Internet of Things company. The IOT card itself is very stable, but the agency quality of the company is uneven. There will be a virtual number of IOT cards used by individuals. For example, the actual flow of 100G is only 60G. At present, the virtual volume of the flow card in the market is 20%~50%, and no one uses it, and the sales company loses money.

In addition, an e-commerce platform, such as a mobile card sold by a treasure, costs from tens to hundreds of yuan, which is very unrealistic and can be said to be profiteering. This kind of card generally doesn't take long, and the seller basically earns the card fee for nothing. The real card cost is only a few dollars. Companies that want you to use it for a long time will not make money by card fees, but by recharging traffic every month.

Is the real-name authentication of IOT card safe? IOT cards are issued in batches in the name of the company and also certified in the name of the company. However, some companies use their own systems for real-name authentication. You take photos of the front and back of your ID card on their platform, and it is more dangerous to scan your face. After all, there are many online loans and the sale of personal information. Since the IOT card is the real-name authentication of the company name, it will be automatically cancelled without recharging the traffic for three consecutive months. In fact, there is no guarantee that individual users can use IOT cards. Although the money spent may not be much, the card may be stopped by the operator at any time because of abnormal traffic, because the operator explicitly prohibits the use of IOT cards in mobile phones.

In addition, some devices including IOT cards (vending machines, bicycles, charging treasures, etc.). Don't disassemble the machine, and it is not feasible to take out the card and insert it into the mobile phone for unlimited traffic, because this machine is generally a small flow card with only a few tens of meters a year. The above personal views are welcome to criticize and correct. Agree with me, please like to go again, thank you! If you like me, please pay attention to me. Thanks again!
