There was a list released by toptenreviews website of top ten cell phone service providers. The list was based on a customer and expert reviews. Verizon wireless still tops the list followed by AT&T at second position and Sprint on the third position. Rest in the order would be T-Mobile, Boost Mobile, Cricket mobile, Virgin Mobile, US Cellular, Metro PCS and lastly TracFone.
