Frequently Asked Questions about IoT SIM Cards

An IoT SIM card is a small card that can be inserted into any compatible device to give it internet connectivity. IoT SIM cards are often used in IoT sensors and devices, as well as in vehicle tracking, point-of-sale terminals, and retail IoT displays.

The Internet of Things (IoT) refers to the billions of devices that are connected to the internet, collecting and sharing data. Cellular IoT simply connects IoT devices using cellular (or mobile) networks. Learn more about IoT connectivity best practices here.

Telnyx charges $1 per SIM card (plus shipping) and then $2 per active SIM per month. You can find more detailed information about Wireless pricing, including data charges here, or to find out more about discounts for bulk orders, please get in touch.

To get started, order a Telnyx IoT SIM card from our easy-to-use Portal. Once you’ve received your SIM, follow the steps in this quickstart guide to start using your data.

Some of the most common cellular IoT connectivity use cases are:

  • Individual hobbyists and engineers: easily add cellular IoT connectivity to projects just by adding a SIM card.
  • Industrial automation and monitoring: adding cellular IoT connectivity to machines and sensors improve efficiency and maintenance routines.
  • Wearable and smart electronics: from smartwatches to smart glasses, and augmented reality—this space is rapidly evolving.

IIoT is an acronym for the “Industrial Internet of Things.” iIoT is largely made up of devices and sensors that help enable industrial automation, improve quality control, and reduce strain on maintenance resources. IIoT is one of the largest markets for IoT devices.

LTE-M is a type of low power wide area network (LPWAN) radio technology standard that enables a wide range of cellular devices and services (specifically for M2M and IoT applications). LTE-M networks consume very low amounts of power, making them perfect for IoT devices in the field.

Machine to Machine (M2M) is direct communication between devices, including wired and wireless. M2M communication is often used for remote monitoring, such as product restocking or smart meters.

Active steering and passive steering are both methods of controlling a SIM card. Active steering means device owners can specify the networks they do and don’t want the device to connect to whereas passive steering simply relies on a priority list of networks. Telnyx offers active steering to give users more control, and ultimately a higher quality connection.
