Best Unlimited Family Plan

Adding lines to your unlimited data plan can lower its monthly price significantly, allowing you to get high-end plans for far less than you would otherwise pay.

Prepaid vs. Postpaid Unlimited Data Plans

In this article, we’ve focused on postpaid unlimited data plans, since they provide the best coverage and the most perks. However, it’s worth noting that there are a variety of smaller prepaid carriers, or MVNOs, that offer unlimited plans as well. Some of these providers include Mint Mobile, Visible, Cox Mobile, Xfinity Mobile, Spectrum Mobile, and Optimum Mobile. 

Before you go the prepaid plan route, know that the coverage aboard these carriers may not be quite as reliable as what you’d get from Verizon, T-Mobile, and AT&T. That’s because they rent space from the major carriers, which prioritize their own customers ahead of those on subcarriers. This can translate to slower speeds in times of network congestion.

How to Pick an Unlimited Data Plan

Before picking an unlimited data mobile plan, here are some important rules of thumb to be aware of. 

Premium Data vs. Deprioritized Data

The first thing to know before choosing an unlimited data plan is that not all unlimited data is created equal. Indeed, there are two types of unlimited data: premium and deprioritized. 

Premium data denotes data that’s fully high-speed, and not subject to slowdowns when the network is busy. So, when you read that a given plan offers 50GB of high-speed data, it’s important to know that once you exceed that amount, your speeds can suffer. Most major carriers offer deprioritized data once that limit is reached, while some prepaid carriers slow your speeds to 3G or worse, which is very slow. 

Deprioritized data can be high-speed data when the network isn’t busy, but it’s subject to slowdowns at any time. This can be frustrating when you’re on the go and need high-speed data for browsing, routefinding, or anything else. 

Cell Phone Coverage

Another important factor to consider before signing up for an unlimited data plan is what kind of coverage the carrier you’re considering offers. 

There are three major cell phone networks in the country: Verizon, T-Mobile, and AT&T. All three offer national 4G LTE and 5G service. Every small carrier, or MVNO, uses one or more of these major networks to provide service to its customers (with one exception—Boost Mobile uses Dish). That’s why the major carrier network coverage debate is relevant to prepaid brand customers, or potential prepaid brand customers, as well. 

AT&T offers the most wide-reaching combination of 4G and 5G service. You can check out the coverage in your specific area by interacting with the coverage map below: 

T-Mobile, meanwhile, lays claim to be most wide-reaching 5G network in the country. Here’s T-Mobile’s 5G coverage map:

Verizon, the largest cell phone carrier in the country, offers excellent nationwide coverage as well. While the company’s cell phone dominance in this arena has slipped a little in recent years, it’s still impressive. Check out Verizon’s cell phone coverage map below: 

How to Access the Fastest Data Speeds

To access the fastest network speeds, having a newer model phone can be helpful. That’s because the latest phones will have the built-in technology to make use of the latest 5G network bands that the carriers bring online. 

Thankfully, carriers big and small are constantly running trade-in promotions that can allow you to score the latest Android devices and iPhones for less than you’d otherwise pay. Typically, these deals come in the form of discounts spread out across your monthly bills, either for 24 or 36 months—all you need is a qualifying phone to turn in. For example, check out the newest Samsung Galaxy S25 trade-in deals for new customers and existing customers alike.

The Bottom Line

The cell phone carrier market is awash with options when it comes to unlimited data plans. Virtually every prepaid and postpaid carrier in the country offers unlimited data plans, and it can be hard to cut through the noise to pick the best ones. 

We’ve tried to do that in this article, as we’ve outlined the best unlimited data plans for families, the best unlimited data plans for perks, and the best unlimited data plans for value.
