Is there a difference between a SIM card and a SIM card?

The IoT has revolutionised how devices communicate and interact. A key factor is the use of SIM cards to enable wireless communication between devices. In this article, we will review the differences and explain the benefits of using IoT SIM cards and explain the difference between LTE-M and 4G/LTE, the latter commonly used for classic data subscriptions. We will also explain the concept of LPWA (Low Power Wide Area)

In-built security features.

IoT SIM cards offer a higher level of security compared to traditional SIM cards. The advanced encryption and authentication technologies used in IoT SIM cards make it harder for unauthorised people to access the device's data or tamper with the communication.

The APN acts as a bridge between devices and the mobile network. IoT SIM cards allow more flexible configuration of APN settings, enabling tailored connections and optimised data traffic. Traditional SIM cards have limited or no APN options at all, which can be a disadvantage in some IoT applications.

Fallback functionality for uninterrupted connection.

IoT SIM cards often offer fallback functionality, which means that if the primary mobile operator's network is not covered or is interrupted, the SIM card automatically connects to other mobile operators' networks in the area. Important when the reliability of the connection is crucial.

Are there different types of IoT SIM cards?

The short answer is yes, there are different ones. We describe two of these here.

IoT SIM cards support various mobile networks, including LTE-M and traditional 4G/LTE. LTE-M is characterised by better penetration capabilities and is therefore suitable for devices that may be placed where coverage is normally poorer, such as below-ground spaces. The PiiGAB 900T LTE is a gateway that supports LTE-M for maximum coverage in difficult environments.

4G/LTE is useful for situations where significantly higher data rates are required, such as in mobile phones and tablets, or other applications that require high bandwidth, such as HD video transmission in surveillance cameras.

What is LPWA (Low Power Wide Area)

LPWA is ideal for Internet of Things (IoT) applications where devices need to send small amounts of data over long distances with minimal energy consumption. LPWA is a connection based on LTE-M technology and other technologies.

In summary, IoT SIM cards offer a host of benefits, with an emphasis on improved security and fallback functionality. IoT SIM cards with support for LTE-M are the optimal choice for metering data collection. You get all these benefits with the PiiGAB SIM Card Service. Simply a safe and reliable solution where you need mobile connectivity for your measurement data collection.
