    A Look at the Fragmented Landscape of IoT Connectivity IoT Connectivity Options Hero

    While use cases for IoT abound and deployments are growing rapidly, the technology landscape can still be overwhelming to newcomers. This article gives an overview of wireless connectivity protocols and their respective strengths, weaknesses, and recommended fields of application.

    The ever-expanding IoT

    Enterprises and government agencies are leveraging Internet of Things (IoT) technology to maximize efficiency and reduce operating expenses while improving service delivery to their constituents. By implementing connected solutions, IoT is driving advancements across a wide variety of vertical industries, including utilities, connected vehicles, agriculture, healthcare, transportation, and security for businesses and homes.

    What is the Difference between eSIM and Embedded SIM in IoT? eSIM vs Embedded SIM

    There is a new kid on the SIM block: the eSIM. But don’t confuse this with embedded SIMs! Oh and there’s eUICC, and 1FF, 2FF, and 3FF, too. And what is an MFF2? This post will help. Let’s dive right in!

    What is a SIM?

    A SIM (Subscriber Identity Module), also called a Universal Integrated Circuit Card or UICC, stores information that uniquely identifies a cellular subscription. For about three decades now, the SIM has been what lets us connect (“attach” in tech speak) our devices to the cellular networks of the world. It holds the credentials and security keys necessary to identify a subscriber. That identity comes in the form of a so-called IMSI number, or International Mobile Subscriber Identity, which is unique for every user or device on or off the network. SIMs also run an application that …

    From Business Case to Deployed IoT Device with Twilio Electric Imp IoT Business Case to Device Electric Imp

    So – you have an idea for building a connected device, which would let you tap into the promises of the Internet of Things. Maybe you’ve worked out a business case, showing how the investment of building the required infrastructure to maintain your device will be counteracted by the benefits expected from being able to collect usage data and control the physical asset. Whatever the case, chances are you’ve underestimated what it takes to build and maintain IoT devices and make everything reliable enough to serve your business properly.

    Twilio’s decades of collective experience helping companies bring IoT products to market unfortunately show us that too many businesses simply fail their business case: it takes them years – not months – to establish reliable connectivity, and many give up before reaching a return on investment or even a functioning deployment.

    In this post, I’ll explain the challenges of IoT, …
