“To put T-Mobile in the best position to continue delivering our customers best-in-class digital first experiences, we are evolving our IT organization,” the company said in a statement. “As we continue to hire for hundreds of new roles, we have eliminated a small portion of positions to realign the focus and structure of some parts of the team. We have offered impacted employees support as they transition.”
So moving IT from the US to India is "Evolving".
