It's no surprise, then, that 79% of T-Mobile customers named price as the No. 1 or 2 factor in choosing the carrier, well ahead of the 50% average. The second most important factor for T-Mobile customers was network coverage, with 55% ranking it a 1 or a 2 in importance.

Is there anything that Sprint has to crow about in our survey? Not really, although it can say that it scored in the middle of the pack for technical support, customer service/billing and phone selection. But that's as good as it gets for Sprint.
What really hurts the company in our ratings is how poorly it performs in its users' eyes when it comes to data speed and network reliability. It was dead last in availability, reliability, download speed and upload speed, and by a wide margin.
Did you choose Sprint based on...
Percentage of Sprint customers who ranked each reason 1 or 2, where 1 is most important and 5 least important
Plan options: 55%
Specific phone: 17%
Source: Computerworld mobile data service survey, 2013
Base: 114 Sprint customers
Sprint customers generally don't think they're getting a good deal, either, because Sprint came in last for value as well.
Despite that, 66% of Sprint customers said price was the No. 1 or 2 reason they chose the carrier, followed by plan options at 55% and network coverage at 51%.
It's a data-centric mobile world, and becoming even more so. That means that data network availability, reliability and speed will continue to be a big differentiator among cell service providers and a primary reason for consumers' carrier choice.
So it's no surprise that Verizon Wireless, which came out on top in our survey for data speed and reliability, has the most U.S. subscribers with 120 million, according to research firm Strategy Analytics. And AT&T, which came in at second fastest in our survey, is also the second most popular provider, with about 105 million subscribers.
But this could all change in a heartbeat: Providers are constantly investing in their data networks, and AT&T and T-Mobile in particular have been rapidly expanding their LTE networks in 2013. And Sprint, which has been hemorrhaging unhappy subscribers, is reportedly considering a buyout of T-Mobile, which would completely change the mobile provider landscape.
