Looking for a way to cut your phone bill? Mint Mobile and Optimum Mobile both offer lower-cost alternatives to the big 3, but they take very different approaches.
Mint Mobile rewards you for paying upfront, letting you lock in some of the lowest wireless rates if you pay for multiple months. Optimum Mobile is designed for Optimum internet customers, offering additional savings when you bundle services.
So, should you prepay for Mint's budget-friendly plans, or take advantage of Optimum Mobile's bundle discounts?
