Twilio ramps up mobile play with programmable SIMs for IoT and handsets with T-Mobile – TechCrunch

Twilio is launching a new product called Programmable Wireless — a SIM-based service that it has built in partnership with T-Mobile so that developers can build full-featured, all-in-one cellular services, to be used wherever they want, whether that’s in an object as part of an IoT network, or even a consumer product, like a new mobile phone service.
