T-Mobile US said Monday it is renaming its MetroPCS prepaid brand to Metro by T-Mobile and adding two new unlimited phone plans that will include Google One cloud storage and Amazon Prime.

The third-largest U.S. wireless carrier awaits regulatory approval for its $26 billion deal to buy smaller rival Sprint. The company is trying to blur the lines between its brands to avoid regulators ordering T-Mobile to divest Metro as a condition to approve the merger.

Rebranding of MetroPCS would also change the perception of the business among people who equated prepaid with low quality, or did not realize MetroPCS operated on T-Mobile's network.

Metro by T-Mobile's top-tier unlimited plan will cost $60 for one line and include both Google One and Amazon Prime.
