So why is this happening all of a sudden? Put simply, the American mobile market is highly saturated—there are fewer and fewer new customers for these carriers. Only 1.1 million Americans got mobile phones for the first time in the first quarter of 2013—the lowest ever growth for that market. Q1 2012 saw around 1.83 million new additions, which shows a quarter-over-quarter loss of 60 percent this year. Meanwhile, there was a modest quarter-over-quarter gain in prepaid customers.
