T-Mobile USA issued its Q1 2012 earnings report today, declaring a net increase of 187,000 new customers. That's a rather notable statistic, considering that the carrier reported a net loss of 526,000 customers in Q4 2011, and losses of 99,000 customers in the first quarter of last year. The company attributed this increase to a surge in prepaid users that helped offset a loss of 510,000 contract customers.

Total revenues, meanwhile, reached $5.0 billion during the first quarter of this year, marking a 2.8 percent decline from Q4 2011, and a 2.5 percent drop from Q1 2011. Net income, meanwhile, totaled $200 million this quarter, up from the $135 million profit it saw in Q1 2011. Operating income rose 7.2 percent over the first quarter of 2011, reaching $1.27 billion, but was down 9 percent from Q4 2011. It should be noted, however, that reported operating income excludes one-off charges of $30 million and $123 million, both of which resulted from its failed merger with AT&T.
