    APIs are the Last Missing Piece to Enable a New Age of IoT APIs are the Last Missing Piece to Enable a New Age of IoT.png

    Now is the perfect time for forward-looking companies to incorporate globally-scaled IoT into their corporate strategy. Smart connected devices act as carriages for these companies to deliver more efficient processes, smarter decision making, and more autonomy to their customers. In this blog post, we will talk about why building IoT solutions is easier than ever before and why achieving scale is only possible by integrating with highly reliable, maintainable, and available APIs.

    What sparked the current explosion of IoT use cases

    The recent conclusion of the “smartphone war” has left players Apple and Google standing at the top. By now, it’s common knowledge that most smartphone users own either an iPhone or an Android. What might not be as obvious, however, is that the remnants of this …

    What is an IoT SIM Card and How is it Used in IoT devices? What is an IoT SIM Card and how is it used?

    An IoT SIM card, also known as M2M SIM Card (machine-to-machine), is a Subscriber Identity Module that is used in IoT (Internet of Things) devices to identify them as they try to connect to a 2G, 3G, 4G-LTE, Cat-M, NB-IoT, or 5G wireless cellular network. IoT SIM cards are typically billed monthly through IoT Data Plans.

    M2M SIM cards, also called Universal Integrated Circuit Cards or UICC, store the credentials and security keys that uniquely identify a cellular subscription. The SIM uses a so-called IMSI number, or International Mobile Subscriber Identity, which is unique for every connected device on or off the network, anywhere in the world. SIMs also run an application that passes that identity information to an onboard cellular modem. The modem in turn, also known as "radio" or "radio module", conducts the actual attachment operation to the network. The application that the SIM card runs, by …

    IoT Fleet Management: Simplify SIM Updates Simplify SIM Updates - Banner

    As IoT fleet operators scale their operations globally, the ability to seamlessly manage thousands of devices for their IoT use case becomes essential. To effectively perform their duties in handling day-to-day IoT-related operations, they require a simple and intuitive interface. This interface should allow them to perform a handful of tasks, ranging from device lifecycle management to usage report analysis, in an efficient manner.

    A recent study by IoT analyst Transforma Insights confirms how more and more organizations express a clear preference for simplicity. The most sought after capabilities from IoT platforms are ease of configuration and bulk tasks:

    How IoT Platforms can Improve the IoT Management Experience

    This comes as no surprise to us. We have heard from customers that they turn to Twilio Console when managing their Super SIMs for cellular IoT connectivity, hoping to do so at scale with little-to-zero engineering work.

    Fleet operators wish to configure their Super SIMs in bulk, activating thousands simultaneously and …

    Considerations for Choosing Embedded MFF2 over Interchangeable SIMs for IoT Devices SIM Card Form Factors - Twilio IoT

    Most of us are familiar with traditional SIM card types, from mini to micro to nano SIMs. These are common in cellular connected hardware. For many types of IoT devices, however, these SIM form factors are impractical. In this article, we will provide guidance on choosing the right SIM form factor; we will specifically examine the advantages of solderable SIMs, also known as embedded SIMs, which are directly mounted on the circuit board (PCB) and cannot be easily removed, like traditional cards. The most common form factor for embedded SIMs is MFF2, a 6x5mm microchip soldered onto your circuit board. We’ll be focusing mainly on these MFF2 SIMs.

    Advantages of soldered-down SIM chips

    When designing your own connected device, or having a product built especially for you, there is the option to order a SIMs internal electronic brain packaged as a microchip to be soldered onto your circuit …

    Cloud to IoT Device Reachability with Super SIM IP Commands IP Commands - Twilio Super SIM

    A requirement we have seen often from developers who use Super SIM in their IoT devices is to be able to “reach out” to a device from a server in their cloud. There are a number of use cases that require this kind of functionality asking the device to:

    • Initiate a connection to a server
    • Report on the status or upload some data (for example sensor data)
    • Download a config or firmware update
    • Take an action and then go back to sleep

    A solution that is used most often is to have the IoT devices set up and maintain a data connection to their cloud. Once connected, the cloud server can send commands via IP messages to the device. However, maintaining a persistent connection from the devices to the cloud comes at a cost: higher data usage and lower battery life.

    We're excited to announce that Twilio now has a …

    Pitfalls to Avoid When Selecting IoT Data Plans IoT Data Plans - Twilio IoT

    If you’re in the IoT world, you know that machine-to-machine cellular data usage is skyrocketing. The average monthly data usage has nearly doubled in just the last three years. Given that dramatic increase in data usage, it’s also no surprise that one of the most common questions we get here at Twilio is how to most cost effectively manage data plans.

    In fact, a recent survey from IDC revealed that when customers looked at data plans, their two top concerns were data costs and pricing models. In fact, managing cost has emerged as a top concern for organizations regardless of use case, deployment location and device fleet size.

    Those same customers outlined the primary sources of their data costs:

    • 65% of organizations are paying for overages and unused data
    • More than 50% of the organizations manage multiple mobile carriers
    • For organizations with multiple domestic mobile operators, their top challenge is …

    IoT Connectivity - How to Choose the Right Option for Your Business IoT Connectivity - Choosing the Right Option | Twilio

    What is IoT connectivity?

    The Internet of Things (IoT) refers to the billions of everyday objects that are now connected to the internet. And the world of IoT is expanding dramatically. IoT technology is being leveraged globally to drive innovation in industries such as healthcare, agriculture, transportation, including connected vehicles, and security. (Find an overview of use cases in our article Top IoT Use Cases Across Industries.) Analyst IDC projected global IoT spending to reach $742 billion in 2020 and predicts the figure will grow 11.3% per year through 2024. Every day, industry leaders are choosing to invest in IoT.

    This is a big deal. This behemoth of technology space is changing the world as we know it, shaping how we live, work, and engage with each other and with the physical world. Predictions on the number of connected IoT devices vary, but we seem to be heading for …

    2G/3G Sunset: How to Future-Proof Your IoT Fleet 2G/3G Sunset: Future-Proof Your IoT Fleet

    If it feels like cellular tech is moving too fast to keep up with, it’s because it’s true! The introduction of 5G—with 6G and beyond already being discussed—means that there’s less space on the spectrum for older networks, leaving those with a fleet of 2G and 3G devices scrambling to upgrade their equipment. IoT-specific networks such as LTE Cat-M are being deployed to more and more regions. Taking this opportunity to upgrade your devices’ IoT SIM cards to a Multi-IMSI architecture and eSIM hardware at the same time will help to future-proof your devices as older technology is phased out and the cost of maintaining outdated hardware increases.

    Wait—what’s happening with 2G and 3G?

    Carriers are the players who ultimately determine whether or not to transition to a new technology, so the sun is setting on 2G and 3G networks at varying rates across the globe. While the dates vary, …
