T-Mobile US raises 2026 post-paid account growth forecast

T-Mobile US raised its 2026 forecast for post-paid net account additions in Q1 2026 to 950,000 to 1 million, up from its previous range of 900,000 to 1 million. The company said the increase reflected new customers switching to its mobile and broadband services.

T-Mobile US reported 217,000 post-paid net account additions across broadband and mobile services in Q1 2026, up 5% year-on-year and above the 193,236 consensus estimate compiled by Visible Alpha. Average monthly post-paid service revenue per account increased 3.9% to $151.93. In February 2026, T-Mobile said it would stop reporting post-paid phone subscriber additions separately and instead focus on account growth and average revenue per account.

T-Mobile US is shifting investor reporting toward account-level growth metrics rather than phone-line additions as it competes for switchers in the US mobile market. The company reported Q1 2026 revenue of $23.1 billion, up 10.6%, and net income of $2.5 billion, down 15%, with the decline partly linked to $476 million in after-tax costs tied to UScellular merger integration, including accelerated depreciation. CEO Srini Gopalan also said T-Mobile does not comment on market speculation after reports that Deutsche Telekom was exploring a merger involving T-Mobile US.
