What is an IoT card?

An IoT card, also known as an M2M (Machine-to-Machine) card, is a specialized communication device designed to connect physical objects to the internet. These devices use technologies like RFID, infrared sensors, GPS, and laser scanners to collect and transmit data. By connecting to the internet through a contractual agreement, IoT cards enable smart systems that can identify, locate, track, monitor, and manage connected devices. In simpler terms, an IoT card is a smart communication tool used in mobile terminals, in-vehicle systems, or other devices to link people, resources, and services efficiently. It is a mobile communication service provided by telecom operators specifically for IoT users, based on public IoT networks. Major telecom companies use their own dedicated number segments to support basic services such as SMS, wireless data, and voice, and offer advanced features like independent connection management and device monitoring.

IoT cards are mainly categorized into MS cards and MP cards. MS cards are typically used for front-loading during manufacturing, while MP cards are suitable for both front and back-end installation. Due to their compact size, durability, heat resistance, and long lifespan, MS cards are commonly used in automotive applications, smart metering, and wearable devices. On the other hand, MP cards are more cost-effective and easier to install, making them widely used in various IoT applications.

Here’s a list of different sizes:

Product Name	Package Form	Model	Specification
M2M Card, Io Card	MP Card (Plug-in Type)	Mini SIM Card	25mm x 15mm
Micro Card	12mm x 15mm
NANO Card	9mm x 12mm
MS Card (Slice Type)	MS0	QFN5*5-8
MS1	QFN5*5-8
MS0	QFN5*6-8
MS1	QFN5*6-8

What is the difference between an IoT card and a SIM card?

Although an IoT card resembles a SIM card in appearance, it functions differently. While it can make calls and send/receive text messages, these features are not commonly used due to higher costs. Instead, IoT cards are primarily designed for data transmission. They offer more cost-effective data plans and are widely used in applications such as mobile payments, POS machines, smart wearables, and vehicle networking. Unlike regular SIM cards, IoT cards are optimized for low-power, long-term connectivity in embedded systems.

Here’s a comparison of network standards used by China’s three major operators:

Network Standard	China Mobile	China Telecom	China Unicom
2G	GSM	CDMA 1x	GSM
3G	TD-SCDMA	CDMA2000	WCDMA
4G	TD-LTE	FDD-LTE	—

When choosing a supplier, it's important to select a reliable and stable provider. Many suppliers operate as resellers, focusing on short-term profit. However, a good supplier should offer long-term support and a strong platform to ensure smooth operation of IoT services. Shopping platforms often act as intermediaries, but the key is to find a partner that provides quality service and continuous operational support for your IoT needs.
