The most recent Windows phone to be launched with a major carrier in the US was the Alcatel IDOL 4S with Windows 10, a T-Mobile exclusive that was unveiled in November. But while the Un-carrier was the last to express faith in the platform, it's now among the first carriers to kill its app for the platform.
Indeed, T-Mobile will be ending support for its Windows phone app on August 25. It's recommended that going forward, customers manage their accounts via the company's web app.
The move isn't surprising, given how frequently developers are leaving the platform. And there have only been a handful of Windows phones ever launched on T-Mobile, with the Alcatel Fierce XL being the only Windows 10 Mobile device besides the IDOL 4S.
Both of the handsets were sold for relatively short periods of time with the Un-carrier, indicating a lack of popularity. The Fierce XL was dropped nine months after its launch, and the IDOL 4S only made it six months, even though the Snapdragon 820-powered phone was heavily discounted to just $288 back in February.
We've reached out to T-Mobile to confirm whether or not the app will still function after the end of support - simply not longer receiving updates - or if it will be killed off entirely. We'll keep you updated if we hear anything.
Update: T-Mobile has confirmed to Neowin that the app will no longer function, issuing the following statement:
That’s correct, the app will no longer have Windows phone functionality.
