The news comes from T-Mobile's chief marketing officer Michael Siever at today's press event announcing the carrier's new LTE network and data plans.
The company did not provide pricing or a specific launch date, but it's the most specific any carrier has been about when the Galaxy S4 will launch.
However, it's safe to assume the Galaxy S4 will cost around $99.99 plus monthly payments of about $20 for 24 months. That's the same pricing plan T-Mobile will use for the iPhone 5 when it goes on sale April 12.
