T-Mobile is set to unveil how its final quarter of 2013 went. With generous discounts to its up-pricing on many high end phones, and reducing many to $0 down over the holidays, it will be interesting to see exactly how good the final quarter was. Of course, we already got a snippet of the information from John Legere at the T-Mobile press event at CES in January. It was – in terms of subscriber additions – a record quarter for the magenta-flavored carrier.

To listen in on the call head over to http://investor.t-mobile.com/ at around 8:50am Eastern time, ready for a 9am start. We’re also expecting a press release to go live around 7am Eastern.
