Deutsche Telekom's T-Mobile U.S. announced on Wednesday that 800,000 subscribers have joined their network.
The Germany-based telecommunications company announced an additional 869,000 subscribers in fourth quarter of 2013.
At the industry conference in Las Vegas, T-Mobile U.S CEO John Legere announced that his company welcomed hundreds of thousands of new subscribers, thus giving it a remarkable turnaround year. He also said that majority of the telecommunications' new subscribers were shifters from AT&T and Sprint, and a smaller but growing fraction were from Verizon.
Legere told the Wall Street Journal, "We are either going to take over this whole industry, or these bastards are going to change."
The fourth largest U.S. wireless network provider has generated increased revenue by offering traditional service contracts and international data fees along with high-end smartphones or other devices and an upgrade to an advanced network service.
The flattering progress resulted from the companies offer in retort of AT&T's promotion that it would grant T-Mobile subscribers up to $450 credit when they shift.
T-Mobile's counter offer is a $650 worth of credit - with as much as $350 in a form of a Visa Card - when they move to their services.
AT&T declined to comment on T-Mobile's new promotion.
The percentage of the network provider's customers shifting to other networks is lower by 1.7 percent in the last three months of 2013 compared to the company's 2.5 percent loss in a year earlier.
During the conference, T-Mobile's executives also ridiculed Sprint, WSJ reports.
T-Mobile CTO Neville Ray described Sprint's network makeover was a "s-storm." While Legere, described the third largest network provider "a pile of spectrum waiting to be turned into a capability."
Bill White, Sprint spokesperson, replied that the company is working hard to make its network better, and T-Mobile "should just worry about their own company."
