MVNOs Offer Big Coverage for a Small Price

The big four carriers have more network capacity than they need for their own customers. Enter MVNOs - Mobile Virtual Network Operators. These alternative carriers lease the extra space and sell to you at discounted rates.

MVNO Benefits:

  • Reliable service on America's four major cellular networks.
  • Keep your phone and your number.
  • Highly rated - often more personalized - customer service.
  • Offer a wide range of custom plans, so you only pay for what you need.
  • Make it easy to sign up online.
  • No contracts or credit checks.

Additionally, most MVNOs offer prepaid plans which means no overage charges or early termination fees.

Key Considerations When Choosing a Cheap Unlimited Data Plan

There are a couple of things to think about before you choose a plan.

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 or 3G 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.

Great Ways To Save on Your Next Smartphone

After so many years of the two-year contract we all got used to upgrading at least every 24 months. But is it really cost-effective to buy a new phone? We don't think so. You wouldn't upgrade your television or your car every two years just because a new model comes out.

Changes to the newest, shiniest smartphones are typically minor. You can save a lot of money by going with one of these options instead of costly device payments:

  1. BYOP: Do you actually need that iPhone X or Samsung Galaxy S9? Bring your own phone instead and prolong its usefulness while saving about $1000.
  2. Buy a used smartphone: Get a great deal on a recent model and save 50% over retail.
  3. Sell your old phone: Earn cash toward a new device by selling your old one. Compare offers for the best deal.

If you do keep your device when switching carriers make sure you know how to unlock it for use on your new service.

Recap

The surge of the MVNO industry means more competition and better unlimited plan prices for you. You can see this trend clearly in our unlimited data plans comparison.

Don't be afraid to break away from the old (expensive) way of buying phone service. Your wallet will thank you!
