All prices valid as of July 21, 2017

If you're hellbent on saving money on your wireless plan, then you have to get away from the Big Four carriers (T-Mobile, AT&T, Sprint, Verizon). Smaller carriers, called mobile virtual network operators (MVNOs) or alternative carriers, lease coverage from the larger networks and resell it for less.

That being said, depending on your usage and needs, a plan from one of the Big Four might actually be your least expensive option. Here we go.

Before choosing a plan

Before you choose a carrier and/or a wireless plan, it's best to first determine your needs and usage habits. If this is your first smartphone, I'd like to first welcome you to the 21st Century and secondly encourage you to try out your options without getting yourself into any yearly or multi-year contracts.

If this ain't your first rodeo, then reflect on your phone habits from the past. How much data have you actually used in an average month? Do you really need an unlimited plan or are you actually on Wi-Fi more than you realize? Could you benefit from an international plan of sorts?

Take time to analyze your usage and then choose the plan that best fits those needs. Most carriers are more concerned with making you overbuy by convincing you that you need unlimited everything, when the fact is that 90% of Americans don't.

Don't let carriers dictate what they think you need, because it will almost always be much more than what's necessary. Figure out what you need and make carriers work for you.

Plans

You could opt for the cheapest data plan there is, but if you end up using more than what's allotted, you could pay far more in overages when you could've just picked the right plan for you. See if these options fit your usage habits.

You're a data hog!

If you're one of the few people who uses more than 10GB of data per month, then you'll probably want to go with an "unlimited" plan from one carrier or another. These plans will usually give you 4G LTE up to around 20GB per month, and if you're going over that, then you deserve a medal.
