I have recently stumbled upon Twillio and it’s definitely quite an interesting company. The company main focus is handling the backend and connecting to various telecom hardware by exposing a globally available cloud API that developers can use to build communications systems.
Here I am writing about the products called Super SIM (one SIM to connect IoT devices globally) and Narrowband (the SDK and developer kit for the NB-IoT). The Super SIM is done in partnerships with Singtel, Telefonica and Three group to provide a SIM card that works everywhere in the world.
The Narrowband focus is currently only on the U.S. and the NB-IoT network of T-mobile. The offering includes Twilio’s Programmable Wireless and SIM card, IoT developer kit with an Arduino-based development board, standard Grove sensors and SDK for optimizing network registrations and communication between devices and the cloud.
