These days, cell phones come with a lot of options, and cell phone users are no longer limited to choosing from just a few big companies. While these big companies often offer the latest phones and calling features, new mobile providers have popped up to fill niches. These smaller mobile providers don’t provide all of the bells and whistles, but they still offer plenty to be excited about. Many offer very cheap, if not free, data plans with unlimited minutes and texts. Plus, none of the companies listed in this post require contracts.
