The Narrowband IoT (NB-IoT) technology promises low cost, low power consumption, wide area coverage, and long battery life, making it suitable for "smart devices". Twilio's Alfa Development Kit is a pioneer in NB-IoT with a development board designed specifically for connecting to T-Mobile's NB-IoT network. The kit includes hardware attachments by Seeed Studio that can be used to develop a NB-IoT "smart device". To connect to the network, developers need to register and activate their Twilio Narrowband SIM in the Twilio Console. The development board uses the Arduino IDE to program the microcontroller and Twilio's Breakout SDK makes it possible for devices to send M2M Commands over the T-Mobile NB-IoT network. After setting up the hardware and software, developers can upload code to the development board using Bootloader mode and then connect to the network, sending a "Hello World" message over the network. The completed project can be found on GitHub under TwilioIoT.
