Among the mobile carriers in the US, I know Verizon is the most aggressive in advancing its LTE network. It has already expanded to more markets in the country and seems like Sprint wants to follow suit. The 4G LTE coverage of Sprint is now available in 40 new areas.
With the expansion, Sprint’s reach is now in about 34o cities across the US. Sprint also promises an enhanced wireless experience right on your mobile phone or tablet with either 3G or 4G. There’s also High Definition Voice feature for noise cancellation during calls plus the Sprint Spark offer that boasts of up to 60Mbps data speed. The latter will soon be available within the next three years in 100 cities in America.
