Analyst says regional carriers will make up 19% of U.S. smartphone sales by 2016

The subscriber base for the smaller Tier 2 and Tier 3 carriers in the United States has always grown slower than that of the Tier 1 carriers, mainly because of the lack of current or cutting edge handset offerings. This seems to be shifting as carriers are upgrading their networks to LTE, and beginning to come to market faster with the latest handsets.
We will be interested to see where the market goes with the smaller carriers. It should be interesting to see what impact the growing number of users will have on the behavior of the big four national carriers. One thing is a given, when a consumer has more choice, a carrier has to work harder to compete, and in the end, the consumer generally benefits in cost or quality.
