Over the course of the last couple of years, the prepaid market in the US has seen an increase amount of customers jumping aboard thanks partly to the enticing and aggressive price plans they offer. Market leaders like MetroPCS and Boost Mobile may have benefited the most, but now T-Mobile is looking to throw its foot into the game. Rumor has it that the number four wireless carrier is expected to launch a new prepaid $50 unlimited talk and text plan that will attempt to compete in the prepaid market. There's no arguing that the carrier offers some of the most aggressive postpaid plan offerings, but they're equally going to match it in the prepaid realm as well. The one unique thing so far that's being heard is that you can choose any device from T-Mobile's lineup to work with this unlimited plan – it's yet unclear if there will be some kind of data add-on for smartphones. We'd suspect that customers would have to purchase the devices at full cost if they opt to go with this plan. So far there is no official word from T-Mobile, but the screenshot from a survey makes it look promising. As much as we'd like to say that a $50 unlimited talk and text plan is good, dropping it down a few notches will not only make it sweeter, but place some strain on the dominant prepaid players in the market.
