Are the zero-monthly-rent data cards sold online IoT cards? What are the risks of using IoT cards?

Many friends have heard that there is a kind of zero-monthly-rent data card circulating on the Internet. The three major operators have not officially launched zero-monthly-rent data cards. Most of the zero-monthly-rent data cards on the market are "Internet of Things cards". They cannot make calls or send text messages, and there are many "pitfalls". Be careful not to be deceived. Let's talk about it in detail below.

Is the zero-monthly-rent data card on the Internet an IoT card?

There is only one possibility for a zero-monthly-rent data card, and that is the IoT card. Only the IoT card can do this without any monthly rent. For example, a common IoT card can buy 30 GB or even more for 19 yuan. Netizens have previously shared a 100 GB card for 19 yuan. However, for this type of data card, the stability of the network and whether the card can be used for a long time are the key considerations.

Moreover, most of these cards are recharged through WeChat official accounts, and the cards can only be used after being activated using the ID number on the back of the card.

What are the risks of using IoT cards?

1. Cards are easily blocked

At present, mobile phone cards have implemented real-name registration, but Internet of Things cards cannot be registered with real names. If used to access the Internet through a mobile phone, once discovered, the card will easily be blocked and unusable.

2. After-sales service is not guaranteed

The Internet of Things card is issued by the operator, but the management rights are in the hands of the agent. We cannot go to a regular business hall to handle recharge, inquiry and other services. We need to go to a third-party agent to handle related services. If the agent "runs away", there is no way to guarantee after-sales service.

Is the Internet speed of IoT card stable?

The network speed is unstable. According to different application scenarios, IoT cards are divided into three types: high-speed, medium-speed, and low-speed. High-speed cards are used in video surveillance, robots and other fields, medium-speed cards are used in logistics and other fields, and low-speed cards are used for smart meter reading, etc. 80% of the cards on the market are low-speed cards, which are the speed of 2G networks, and the user experience is very poor.
