AT&T, T-Mobile Offer Best 3G Performance
The 3G networks operated by AT&T and T-Mobile handily beat those operated by Sprint and Verizon Wireless in PCMag's Fastest Mobile Networks in 2014. AT&T and T-Mobile use HSPA/HSPA for 3G and Sprint and Verizon use CDMA EVDO Rev. A for 3G. For its purposes, PCMag defined 4G/3G based on speed thresholds possible by each network type. It set minimums for average download speeds and then tested the 4G/3G networks accordingly. T-Mobile's 3G network offered the fastest national average download speeds of 8.6Mbps, with a 28.5Mbps peak. T-Mobile's 3G network, for the most part, exceeded the marketing claims made by the company. AT&T's 3G network delivered a national average download speed of 3.8Mbps, with a 15.5Mbps peak. Both Sprint and Verizon saw national average download speeds of just 0.7Mbps, with peaks at 2.5Mbps and 2.7Mbps, respectively. Phones that can't connect to LTE networks fall back to the available 3G networks. PCMag's data clearly shows that AT&T and T-Mobile offer a better 3G experience when their LTE isn't available. Sprint and Verizon's 3G networks are limited by the CDMA EVDO technology used to run them. Though Verizon's 3G network may be slow, its LTE network was ranked the fastest and most reliable by PCMag.
