Frequently asked questions about our IoT SIM cards

An IoT SIM card is a physical chip inserted into an IoT device to enable cellular connectivity for a range of IoT applications. An IoT eSIM is a reprogrammable, embedded SIM that can be remotely provisioned with network profiles. IoT SIM cards are commonly used in devices that are more accessible, such as cameras and push-to-talk radios. As eSIM eliminates the need for a physical swap, they are commonly used in remote or difficult-to-access IoT deployments. Learn more about IoT eSIMs.

M2M SIM cards are specifically designed to support communications between machine to machine, primarily in highly industrial applications. Common use cases include the exchange of information between meters or monitoring equipment. IoT SIM cards support a wider range of applications from sensors to cameras. IoT SIM cards are designed to support larger-scale deployments, especially those that span international borders.

IoT SIM cards are specifically designed to deliver connectivity to IoT devices. They are built to withstand harsher conditions, have a greater number of read/write cycles and generally have a longer lifespan. IoT SIM cards are more secure than consumer or mobile broadband SIM cards as they have more advanced security features including private and public IP addresses, L2TP and IPSec tunnelling, and secure remote VPN access. Finally, some IoT SIM cards can allow the IoT device to connect to multiple networks, providing enhanced network resilience to the deployment. Learn more about Cellhire’s multi-network IoT SIM card.

The price of an IoT SIM card depends on where your device will be deployed and how much data it will use. Cellhire is proud to offer the most competitive rates on data, as low as £1.70 per GB. Find out how much you could save using our IoT data savings calculator.
