T-Mobile is running a limited-time promotion for its T-Mobile Fiber service for customers signing up for the 2 Gig plan. Multiple outlets report that the deal includes the customer’s first month of service at no cost and provides an additional $100 benefit. The promotion is tied specifically to the 2 Gig tier, and the reported $100 is delivered as a virtual prepaid Mastercard. One source describes the incentive as “get $100 back,” while another emphasizes the bonus as part of a sign-up process. The coverage also outlines that interested customers need to follow the offer-claim instructions to receive the benefit. While both reports agree on the core terms—first month included and a $100 prepaid Mastercard bonus for 2 Gig sign-ups—they focus on the practical steps for claiming the promotion rather than providing additional changes to pricing, speeds, or service terms beyond the introductory offer. The offer is presented as time-limited, so eligibility is dependent on signing up within the promotion window.
