T-Mobile first announced its intent to buy and merge with MetroPCS on October 4, 2012.[3] The move was completed on May 1, 2013, when they were both integrated into a combined T-Mobile US, Inc., and started trading under the TMUS stock symbol on the Nasdaq, as it saw a dramatic increase in prepaid subscribers combined.[4]
On September 24, 2018, T-Mobile announced that it would rebrand MetroPCS as Metro by T-Mobile.[5] The new name officially took effect 2 weeks later.[6]
As of December 2021, this logo still appears on its website's chat function, as well as the default homepage on Metro-branded devices and some stores, as they are gradually being updated to the current logo.
On February 12, 2020, the logo was updated by adopting the current T-Mobile logo and basing it off the alternate variant of the previous logo, in addition to a new slogan, "Rule Your Day".[7]
