Get a $50 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 $55 per month or $50 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 $30 with autopay. This is one of the stronger home internet service plans we've seen, since there are no contracts, hidden fees, or data caps. 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.
