What is t mobile play?

As an AI language model, I do not have access to current information about T-Mobile Play, but historically, T-Mobile Play was a streaming service offered by T-Mobile to subscribers of its services. It was launched in November 2018 and offered a variety of content, including TV shows and movies. However, in July 2020, T-Mobile announced that it was discontinuing T-Mobile Play and would instead be partnering with Netflix to offer its customers a year of free Netflix service.
