    How to Pave the Way to Manageable Global IoT Deployments with Multi-IMSI SIMs Global IoT Deployments with Multi-IMSI SIMs - Twilio IoT

    Did you know that many IoT projects either don’t reach their ROIs as quickly as intended or fail altogether? In fact, only 26% of companies have had an initiative that they considered a complete success and 60% of initiatives don’t even make it past the Proof of Concept stage. Complexity is to blame—complexity stemming from the need to tackle many different layers of technology for a successful IoT deployment, but also complexity within layers such as connectivity itself. This article introduces the cellular complexity challenge, and shows ways to address it.

    The cellular complexity challenge

    We applaud the availability of cellular networks around the globe, but behind each network are individual carriers, which are commercial businesses in most cases; interoperability, openness, or accessibility are not their top concerns, but it is those attributes that anyone planning to deploy across borders would require for a global implementation that remains manageable and …

    When to Use LTE Cat M for IoT Devices When to Use LTE Cat M for IoT Devices HEader

    What is Cat M?

    LTE Cat M (also known as LTE-M) is a low power wide area (LPWA) technology designed to support “Massive IoT”, i.e. billions of IoT devices, with cellular technologies. Today Cat M is mostly referring to Cat M1, as Cat M2 adoption will take a few more years.

    LTE radio technology uses “categories” to differentiate the capability of each device that attaches to an LTE network. For example, Cat 1 refers to devices that can support download speeds up to 10 Mbps, while Cat 4 refers to devices that can use carrier aggregation and support download speeds up to 150 Mbps. Cat M1 refers to a category of devices that operate on a narrow 1.4 MHz channel with observed download speeds in the 589 Kbps range, and 1.1 Mbps on the uplink (3GPP release 14). The older Cat M modules have even lower speeds (300 Kbps …

    The Benefits of “Consumer Profile” eSIMs for IoT devices ConsumerProfiles_BlogHeader.png

    eUICC SIMs (aka eSIM) present a significant step forward in cellular connectivity for IoT devices. What does the architecture look like for implementing eUICC SIMs? This article provides a technical deeper dive and explains the benefits of the so-called Consumer Profile architecture over M2M Profiles.

    The convenience of deploying SIMs digitally

    If you are deploying a fleet of IoT devices, you don’t have to worry about buying SIMs, getting them shipped and clearing customs, managing an inventory of physical SIMs and having a process in place for swapping SIMs when needed. eUICC SIMs eliminates all of that by converting a physical SIM into a digital profile that can be downloaded on-demand onto an eUICC SIM.

    For unmanaged IoT devices, eSIM/eUICC means you can deploy once and never have to visit the device location for a SIM swap to change your connectivity provider.

    eUICC SIMs are also known popularly as eSIM, …
