Sidekick can keep T-Mobile from hemorrhaging customers, it seems, as the company reported significant losses in its Q1 statement for 2011. According to official Q1 financials, 471,000 contract customers either failed to re-up, or outright canceled their contracts. Stacked against a shortcoming growth of just 372,000 prepaid customers (including MVNO customers for sub-carriers), T-Mobile suffered a net loss of 99,000 users, a 29-percent increase in losses over the same period for the previous year. Ouch. The firm chalked its loss to increased "competitive pressures," which lends credence to AT&T's insistence that Sprint and Verizon are such fierce opponents that it has to acquire T-Mobile for the magenta-tinted carrier to stay in the game.
