According to the NY Post, T-Mobile is cooking up a Plan B in case the deal with SoftBank (owners of Sprint) fails to materialize. The media says that John Legere & crew are shopping for spectrum from the Un-carrier's smaller competitors. T-Mobile is interested in low-band spectrum, which penetrates concrete and walls better. Still, the carrier might be forced to sell some of the new spectrum if it merges with Sprint successfully. Reportedly, Sprint has bowed to a $2 billion breakup fee if the FCC busts the acquisition.
This April, T-Mobile purchased $3.3 billion worth of spectrum from Verizon. The carrier's 700MHz A-band spectrum covers half the USA, while most of the remainder is spread among 33 smaller carriers, such as US Cellular and Vulcan Inc. Hopefully, if the Sprint acquisiton falls through, T-Mobile will be able to offer better coverage to its increasing user base.
