The best cheap unlimited data plans in September

Check Carrier Coverage

Cheap unlimited data plan benefits

MVNOs use the same coverage through a major carrier (AT&T, T-Mobile, Verizon) by leasing both tower storage and space from the carrier.

This allows MVNOs to resell customizable plans without the worry of added overhead. Remember, they're just leasing the space they need to give you an alternative to paying the high cost of the "big four" carriers.

Excited by what you hear? The biggest benefit of all may be what doesn't happen: You aren't forced into long-term contracts for your two-line phone plan. No more signing off for the next 24 months. Instead, you can use your phone knowing that you can make changes month-to-month.

  • Same great nationwide coverage: These cell phone carriers operate on the very same networks as the big four carriers.

  • Much lower prices: Save up to $600 per year on your cell phone plan. Why are MVNOs so much cheaper? They don't have the huge overhead and advertising costs the big guys do.

  • No contracts: Don't get trapped into a two-year agreement. Switch carriers when you decide to with a no contract phone plan.

  • Same cell phone service: Just because you're paying less, that doesn't mean you have to scrimp on features. Plans with unlimited everything are easy to find from these prepaid carriers. Usually, a low cost carrier plan comes with unlimited talk and text as standard, high speed data, and even mobile hotspot data features.

  • Keep your phone and number: You can bring your own phone and keep your phone number. No need to sign up for pricey device payments.

  • Customize your plan: You decide how much data you need. Choose to pay as you go, opt for unlimited or no data, minimal minutes, or unlimited talk text and data. Unlimited data plans come at a much better price with an alternative carrier. Pick the plan options that fit your budget - not the one your carrier thinks you need.

  • Great customer support: Smaller mobile providers are known for their attention to their customers. Stop feeling like an anonymous number getting lost in the crowd! Check out our carrier user reviews before switching.

Cheap unlimited data plan features

  • 4G LTE data speeds: Since MVNOs operate on the big four cellular networks you'll pay less without sacrificing speed. More and more are adding 5G coverage all the time so you can expect high-speed data.

  • Unlimited talk and text messaging: Finding a new unlimited plan has never been easier. Virtually all small carriers include unlimited text and calls in their plan options. Compare cheap talk and text plans with or without data.

  • International calls to Canada and Mexico: International calling is a must for many people. Luckily MVNOs offer some of the best international phone plans, with free calling to certain countries like Canada and Mexico, and discounted rates on others.

  • Multiline discounts: Low-cost carriers also offer some of the cheapest family cell phone plans, with multi-line discounts.

  • Wi-Fi calling: This feature is handy when you're out of your service area, allowing you to make calls over the internet instead of on your cellular connection.

  • Tethering/hotspot data: Many low-cost carriers allow you to use your phone as a hotspot. Pick an MVNO with the best mobile hotspot plans so you can share your mobile hotspot data with other devices.

  • HD video streaming: Just like the big guys, some MVNOs offer HD video streaming and some don't. Read the fine print to find the option you want.

Carrier coverage comparison

Which prepaid carrier is best for you? That depends on which network has the best coverage in your area.

Whether you go with a GSM carrier (T-Mobile and AT&T) or a CDMA carrier (Verizon) you'll enjoy national coverage, just like with the major carriers.

Cheap unlimited data plan types

Do you actually need unlimited data?

Have you monitored your phone data usage to see how much you actually need? You can typically see this information in your device settings or in your account through your wireless carrier.

The truth is that most people don't need unlimited high-speed data. For truly high data users unlimited may be a good choice. This is likely only the case if you spend a lot of time doing HD video streaming or gaming away from your home Wi-Fi.

We make it easy to find the right monthly plan for your needs:

Is unlimited data really unlimited?

The term is misleading in a way. Yes, you get a much larger allowance at 4G LTE speeds- but (sorry, there's always a but!) - most carriers reserve the right to throttle service to 2G speeds after a certain amount of use. T-Mobile has the highest deprioritization threshold at 50 GB while others may be as low as 22 GB.

That doesn't mean you definitely will be throttled. If you've reached your high-speed limit most carriers will throttle in times of cellular traffic congestion (peak times). Of course, the reality is that only a very small fraction of smartphone users even reach this threshold in the first place.

It's always a good idea to read the terms and conditions in the fine print.


How to switch to a cheaper unlimited plan

It's never been easier to switch. Let's break it down.

  1. Customize your plan. Whether you're looking for a truly unlimited plan, or in the market for something more basic, choose a plan to suit your cell phone needs.

  2. Prepare to make the switch. Make sure your old bills are paid up and your phone is unlocked. If you're getting a new device, transferring data from one to another is simple. Even if you're going from an iPhone to Android, and vice versa.

  3. Set up your new plan. Keep your current carrier account open until your number has ported over. Once you're sure your new plan is up and running, cancel your old account. If you've got a new device with your Tello plan, it should be ready to use when it arrives. If you're bringing your own phone then you'll need to follow the instructions with the new SIM card kit that Tello will send to you in the post.
