How to choose between them
Start with the network that covers your home and daily routes best, then pick the cheapest plan on it. If you use a lot of data in busy places, look for plans with more high-speed (premium) data; if you mostly use Wi-Fi, the cheapest plan is usually all you need. Our guide MVNO vs. major carrier explains when priority data matters.

Frequently asked questions
Is "unlimited" really unlimited?
You will not be cut off or charged for overage on these plans, but most slow your speeds after a set amount of high-speed data, or when the network is busy. That limit is listed for every plan below.
Why are some prices for 6 or 12 months?
Brands like Mint Mobile sell plans paid in advance for several months, and some brands offer a lower intro price for new customers. We rank by the average price over the first 12 months, so you can compare fairly.
