T-Mobile’s collaboration with Twilio has produced a software development kit (SDK) for the operator’s NB‑IoT network, aimed at simplifying development and accelerating deployment of low-power, wide-area IoT devices.
NB‑IoT (Narrowband Internet of Things) is a wide-area, low-power cellular technology designed for small, infrequent data transmissions. By dramatically reducing energy consumption, NB‑IoT extends battery life for devices and lowers maintenance costs, making it attractive for long-term deployments such as smart metering, asset tracking, and health monitoring.
In a company statement, T‑Mobile highlighted the efficiency benefits of NB‑IoT:
“With NB‑IoT, devices can consume a fraction of the battery power they do with previous cellular M2M devices, enabling connectivity at a fraction of the cost. NB‑IoT is built for smaller data packets, such as timestamps, GPS coordinates and status updates for a variety of industries, from smart metering to health device monitoring. With the power and cost efficiencies generated by NB‑IoT, the market is ripe to open for new categories of lower cost, battery efficient internet‑connected devices that don’t exist today. T‑Mobile is the first to deploy an NB‑IoT network in the US, which launched nationwide in July.”
Twilio’s offering builds on its Programmable Wireless service, expanding support to include NB‑IoT and enabling developers to integrate narrowband connectivity into their applications more easily. John Legere, T‑Mobile’s CEO at the time, noted that the partnership aims to unleash developers and foster a new ecosystem of IoT solutions.
The collaboration between T‑Mobile and Twilio began in 2016; recent developments show the partners moving faster to bring practical tooling to market. Twilio Narrowband is positioned as the first developer platform for NB‑IoT in the United States and includes the Breakout Software Development Kit to help developers optimize their IoT solutions.
The Breakout SDK handles essential functions such as network registration and manages communication between devices and cloud services. It intelligently optimizes data exchange depending on network capabilities, supporting IP, non‑IP, and SMS transport methods to suit various use cases and device constraints.
Chetan Chaudhary, GM and VP of IoT at Twilio, explained that applying Twilio’s proven approach for cellular IoT to Narrowband reduces complexity and removes barriers for developers, allowing them to focus on hardware design and novel use cases rather than low-level connectivity management.
Twilio announced that the Narrowband Developer Platform would be available in the U.S. as a beta offering in early 2019. The service was presented with three pricing tiers intended to accommodate different stages of development and scale:
-
Developer plan: $2 per device per month
-
Production annual plan: $10 per device per year, or $5 per device per year at scale
-
Production five‑year plan: $8 per device per year, or $4 per device per year at scale
This SDK and platform aim to make it easier for startups and established companies to prototype, test, and roll out NB‑IoT devices by streamlining connectivity management and offering predictable pricing options. For developers and product teams considering low‑power wide‑area deployments, such tooling helps reduce time to market and operational complexity without introducing new technical burdens.
