Unlimited data under $30 sounds like one of those deals that’s “real” until you click the fine print.

But here’s the truth: there are actually some very solid unlimited plans under $30 for a single line.

The catch is this:

“Unlimited” doesn’t always mean unlimited high-speed data.

Some plans slow you down after a certain amount of data. Some may slow down when the network is busy. Some include hotspot, some barely do, and some make you pay extra.

So in this guide, we’re doing two things:

1. Comparing the best unlimited plans under $30 for one line
   
   
2. Explaining what “unlimited” really means so you don’t accidentally choose a plan that feels great for 5 days and painful for the rest of the month

Let’s get into it.

Quick Answer: What’s the Best Unlimited Plan Under $30 for One Line?

If you want the fastest answer…

Best Overall for Most People: Visible Base ($25/month)

It’s one of the cleanest, simplest, no-surprises unlimited deals under $30, especially if Verizon works well in your area.

But depending on what you need (hotspot, premium high-speed data, prepay discounts, etc.), another plan may fit better.

So here’s the full list.

What “Unlimited Data” Actually Means (In Normal Person Terms)

Before we compare plans, here’s the quick cheat sheet. This will make the whole post way easier to understand.

1) Unlimited does not always mean unlimited high-speed data

Many “unlimited” plans give you a set amount of high-speed data (like 50GB), then slow you down after that. You can keep using data, but it won’t feel the same.

2) Some plans slow down during congestion

This is called deprioritization. It means your speeds may slow down when the network is busy (like crowded cities, concerts, airports, stadiums).

3) Hotspot rules vary a lot

Some plans include hotspot. Some include a tiny amount. Some include it but limit the speed. Some charge extra.

If you work remotely, travel, or use your phone as Wi-Fi for a laptop, hotspot matters.

How We Picked These Plans

To make it onto this list, a plan had to meet these requirements:

• Under $30/month for one line (either month-to-month or through a legit prepay option)
  
  
• Unlimited data included
  
  
• Widely available and easy to sign up for
  
  
• Not a one-day-only promo that disappears instantly

Best Unlimited Phone Plans Under $30 (Single Line)

1) Visible — $25/month

Verdict: One of the best “power user” unlimited plans under $30, especially if you want a bigger premium data bucket than most budget plans.

3) Boost Mobile Unlimited — $10/month

Boost is one of the most common “cheap unlimited” carriers for a reason. You typically get unlimited talk, text, and data, but your speeds may slow after you hit a premium data threshold. View Boost’s plan here.

Best for: People who want unlimited under $30 and don’t mind some fine print around high-speed data limits.

Verdict: Great price, common pick, just make sure you’re okay with the premium data cap if you stream or use a lot of data every day.

4) Tello Unlimited — $25/month

Tello is a budget carrier on T-Mobile’s network with a surprisingly solid unlimited plan. It includes unlimited talk and text. It’s easy to customize if your needs change later. View Tello’s plan here.

5) Mint Mobile Unlimited — $30/month (best price usually requires prepay)

Best for: People who want T-Mobile coverage and don’t mind prepaying to get the best deal.

Verdict: Mint is a classic choice for cheap unlimited, but it’s best if you’re comfortable paying in bulk and staying for a while.

6) Red Pocket Unlimited Premium — $30/month

Red Pocket’s Unlimited Premium plan gives you a solid chunk of high-speed data each month, then reduced speeds after you hit the threshold. It’s a great option for deal hunters who want a more clearly defined high-speed allowance. View Red Pocket’s plan here.

Best for: People who want a bigger high-speed data limit and prefer a more structured plan.

Verdict: A strong alternative to the $25 plans, especially if you want a clearer “here’s what you get” setup.

FAQ: Unlimited Under $30

Is unlimited data under $30 actually unlimited?

Yes, but many plans include a high-speed limit. After that threshold, you can keep using data, but speeds may slow down.

Will I notice deprioritization?

Sometimes. If you’re in a crowded area or use data during peak times, you might notice slower speeds on budget plans.

How much data do most people use?

If you stream video daily, scroll social apps often, or use your phone as hotspot, you can burn through 30–50GB faster than you think.

Can I keep my number when switching?

Yes. Most carriers make number transfer easy, and you can usually do it online.
