AT&T pulled out of the deal and Humm turned his focus toward making T-Mobile the most affordable carrier amongst the nation's top four mobile operators. T-Mobile, though. has been losing post-paid customers and its pre-paid business has been bailing the company out.
Humm also was in the CEO's office at a time that T-Mobile became a force in 4G with its HSPA+ 42Mbps network. Recent tests showed that network beating Verizon's LTE pipeline in 11 cities. The mobile operator is currently planning out an LTE network of its own using its AWS spectrum for the service. T-Mobile has a deal with Verizon to buy some of the latter's AWS spectrum only if Verizon gets approval from the Feds to close a deal it has to purchase spectrum from a group of cable companies. Humm was never able to get the Apple iPhone for his customers, although 1 million unlocked units are said to be running over T-Mobile's pipeline.
