T-Mobile has been pretty aggressive over the past few months in their bid to attract more customers over onto its network, but has their efforts proven to be a success so far? Well as it turns out, despite the naysayers and the critics, T-Mobile has done surprisingly well as the company has recently announced that they have managed to add an additional 1.6 million customers in the last quarter of 2013.

T-Mobile held its much anticipated media event in Las Vegas yesterday announcing the arrival of its Uncarrier 4.0 plans. Along with that, the carrier also published its performance results from the last two years, showing a massive growth in the last quarter of 2013. T-Mobile reportedly added over 1.6 million customers in the last three months of 2013, thanks to the massive ad campaign and the competitive pricing.
