Sprint likes to call itself "the Now Network," but it really should be named "the Promise Network," because right now all it is selling is the promise of 4G LTE at some point in the future. The carrier recently announced that it is dumping its mediocre 4G WiMAX network in favor of LTE on new handsets. That's the right move long-term, but it leaves current Sprint customers in a bind.
The company is selling 4G LTE phones such as the Samsung Galaxy Nexus and LG Viper 4G LTE, but they'll only get a 3G signal until Sprint launches its new network. The carrier plans to roll out LTE this summer to just six cities -- Atlanta, Baltimore, Dallas, Houston, Kansas City and San Antonio -- with no ETA for other cities apart from 123 million people covered by the end of the year. Even if you live in one of the designated six markets, there's no guarantee that Sprint's implementation of LTE will be as fast as AT&T and Verizon's; we just don't know.
Whether you are already a Sprint customer or are just thinking of becoming one, you should wait to see how quickly the company's version of LTE is coming to your area and whether it actually lives up to the hype. You don't want to buy that Evo 4G LTE today, only to be stuck with 2007-era 3G speeds while your friends on Verizon and AT&T are cruising along at 4G.
