T-Mobile began in 1994 as VoiceStream Wireless PCS, a subsidiary of Western Wireless.
In 1999, Western spun off VoiceStream as an independent company.
In 2002, VoiceStream changed its name to T-Mobile USA. This company is the US operation of T-Mobile International AG, a subsidary of Deutsche Telekom.
In 2011, AT&T announced plans to merge with Deutsche Telekom. This merger faced a lot of regulatory pressure from the US government and AT&T eventually withdrew their bid.
In 2013, T-Mobile merged with MetroPCS Communications to form T-Mobile US, a publicly traded company.
The company has had problems in 2016 with LTE data lines going out for long periods of time. Representatives blame the problems on “upgrades”, but insist the problems are minimal.
In mid-2016, the company announced that it would be introducing 5G, with amazing speeds of 12 gigbits per second. This would be three times faster than what Verizon can offer. However, 5G has an estimated start date of “sometime” in 2018.
The company offered a free iPhone 7 (preorder) for those trading in an iPhone 6 during the month of September, 2016. Customers need sign up for an unlimited data plan and a 2 year service agreement.
Today, T-Mobile US operates the 3rd and 4th largest wireless providers in the US. Together, they provide service to over 63 million customers.
