Apple began to pursue the prepaid market more aggressively in 2016, as the market research firm gap intelligence noted in September, and that pursuit has only grown more ambitious over the last year. The iPhone’s prepaid retail channel placements more than doubled from the second quarter of 2016 to the second quarter of 2017, growing from 15 SKUs to 46 SKUs, and they increased 35% from the first quarter of this year to the second quarter, according to fresh data from the San Diego-based firm.

And:

Meanwhile, Apple secured a new prepaid distribution deal through Costco in the second quarter, and it increased prepaid retail placements at AT&T (up 200% quarter over quarter) and Best Buy (up 125% quarter over quarter), according to gap intelligence. The iPhone has seen 15 new retail placements across five prepaid carriers recently, gap intelligence said.

Who owns the pre-paid market? Android. This is a natural market for the iPhone SE, 5s, and 6, Apple finding ways to sell more phones, compete in every market.
