Boost Mobile vs Optimum Mobile plans
Winner: Boost Mobile
Boost Mobile offers low-cost prepaid plans that are available to anyone, no strings attached. Whether you want just a little data or a full unlimited plan, Boost's pricing beats most competitors with no internet bundle required.
Optimum Mobile's prices look cheap at first glance, but that's only if you're also an Optimum internet customer. If you want phone service on its own, the rates jump up significantly.
Takeaway: If you don't have Optimum Internet, Boost Mobile is the clear winner. Even if you do, Boost's unlimited plan costs less than Optimum's smaller plans.
