T-Mobile misses quarterly revenue estimates as competition bites

T-Mobile US Inc missed fourth-quarter revenue estimates on Wednesday despite adding thousands of wireless subscribers, as competitors ramped up their holiday season handset offers to lure customers.

The U.S. wireless carrier has been adding thousands of wireless subscribers lately, thanks to discounts on smartphones, bundled offerings, industry-low plan prices and an edge in 5G, owing to its $23 billion buyout of Sprint Corp. in 2020.
