The last paragraph of the (very short) article says this:
> India is the world's second-largest smartphone market after China, but India is an extremely competitive, price-conscious market that Apple has struggled in, only capturing around 3 percent of the market. One way for Apple to lower prices in India is to build phones locally, allowing it to dodge Indian import fees that are especially high on goods made in China. The Wistron plant, naturally, makes Apple's cheapest phone, the iPhone SE.
