Get a $150 prepaid virtual Mastercard when you switch to T-Mobile Home Internet. This is a limited-time offer. You'll need to fill out this form to check for availability in your area before signing up for the service. T-Mobile Home Internet costs $65 per month or $60 with autopay. If you're a current T-Mobile cellular customer with a Magenta MAX plan, you can drop the price of this plan from down to $40 with autopay. There are no contracts, hidden fees, or data caps with this plan. T-Mobile also offers a 15-day free trial and a Price Lock guarantee, so your rate won't increase after a promotional period, like with traditional ISPs.
