Metro PCS Corporate Office

Metro PCS began in 1994 as General Wireless, Inc. The company was founded by current CEO, Roger Linquist, and Malcolm Lorang, both of whom were executives with PageMart.

MetroPCS provides nationwide talk, text, and data depending on the plan services using GSM, HSPA, HSPA+ and 4G LTE networks. MetroPCS previously operated the sixth largest mobile telecommunications network in the United States using CDMA technology.

In 1998, MetroPCS filed Chapter 11 bankruptcy and emerged from bankruptcy in 1998.

In 2004, MetroPCS Communications began a subsidiary of Metro PCS as part of their restructuring.

At a time when most cell phone companies were charging high fees for data usage and international texting, MetroPCS was offering a flat $50 a month fee with unlimited texting and data, along with a $5 monthly plan which allowed for unlimited international texting, as well as calls to landline phones.

In 2009, a 3G network was launched. This was followed by the launch of an LTE network in 2010.

MetroPCS was the 6th largest wireless network in the US with 9.5 million subscribers. Although the company is a Delaware corporation, the Metro PCS corporate office is located in Richardson, Texas.

In April of 2013, Metro PCS was acquired by T-Mobile, USA. Although executives at T-Mobile had stated at the time of the acquisition that all locations would be rebranded into T-Mobile locations, this has yet to occur.

T-Mobile is now considering a merger with Sprint. If this is approved, it might mean higher prices for MetroPCS customers.

After the merger with Sprint, Metro PCS is being rebranded to Metro by T-Mobile.
