T-Mobile is offering new customers up to $300 in prepaid Mastercard credits when they sign up for 5G Home Internet plans, plus a free month of service. The promotion applies to three tiers: the introductory Rely plan gets you $100, Amplified earns $200, and the premium All-In plan delivers the full $300 credit. This deal represents one of the carrier's most aggressive pushes into the home internet market yet.

Beyond the cash incentive, T-Mobile's 5G Home Internet starts at $50 per month with AutoPay or $35 when bundled with a mobile plan. All tiers include unlimited data, a free Gateway device, and a 15-day money-back guarantee. The service also features a five-year price lock and no equipment fees or contracts. The All-In plan, priced at $70 monthly with AutoPay, adds extras like a mesh Wi-Fi extender, 24/7 tech support, and free streaming subscriptions to Hulu and Paramount Plus.

This promotion could significantly impact competition in the home internet space, particularly against cable providers. With broadband prices rising nationwide, T-Mobile's combination of high-speed 5G coverage, generous incentives, and transparent pricing makes this offer particularly attractive for consumers looking to cut costs while maintaining reliable connectivity.
