As we look to 2026, we’re even more confident that the future is brighter than ever before. We see continued opportunity to eliminate customer pain points, introduce even more consumers to the Un-carrier ethos, and further extend our network leadership while accelerating our digital transformation to drive durable and outsized profitable growth.
