Mint Mobile 3-Month Unlimited Plans $45

For a limited time, new customers can sign up for any Unlimited Plan at Mint Mobile and get their first three months for just $15 per month. You'll only pay $45 upfront. Each Unlimited plan includes unlimited talk, text, and data at 5G speeds. Plus, every plan comes with a 3-in-1 SIM Card Kit, allowing you to use your own unlocked phone. After three months, the plan price reverts to its regular rate, but you can cancel anytime.
