High inflation and macro economic challenges have forced consumers to cut back spending even as rivals undercut each other with cheaper and bundled offerings, leading to customer churn at top wireless carriers.

T-Mobile's total revenue in the quarter ended March fell 2.4% to $19.63 billion, missing analysts' estimate of $19.82 billion, according to Refinitiv.

T-Mobile added 538,000 monthly bill-paying phone subscribers in the quarter, compared to analysts' expectation of 547,800 net additions, according to FactSet. The company added 927,000 in the December quarter.

T-Mobile, however, raised its full-year forecast for wireless subscriber growth.

It now expects wireless subscriber net additions between 5.3 million and 5.7 million, compared with its earlier forecast of 5.0 million to 5.5 million in the year through December.

Analysts and investors generally watch wireless subscriber phone figures closely as those customers pay a recurring monthly bill, making them valuable to the carriers.
