Border agents in the US are dramatically stepping up searches of people coming into the country, even US citizens returning from trips. And they have the authority to search your personal devices. With your phone adding another layer to concerns about crossing the border, you have more to consider when traveling than ever.

This isn’t just hyperbole. According to new figures from US Customs and Border Protection, nearly 15,000 device searches were carried out between April and June — over 1,000 of them using advanced tools that copy or analyze a phone’s contents. The rising numbers raise questions about how much personal data travelers may be handing over without realizing it.  So what’s the solution? A burner phone. It’s the ultimate defense for keeping your personal data private when you travel, ensuring you stay connected without handing over your entire digital life at the border.

But the appeal goes beyond security. A stripped-down phone is also the perfect escape from the constant notifications and screen-time vortex of your primary device. Even celebrities like Conan O’Brien have embraced simpler phones to cut through the noise. Whether you’re crossing a border or just trying to cross the street without distractions, a burner might be the smartest tech you own.

Although carriers have offered prepaid phones since the ’90s, “burner phones” or “burners” became popular in the 2000s following the celebrated HBO series The Wire, where they helped characters avoid getting caught by the police. Although often portrayed in that light, burners aren’t only used by criminals, but really by anyone concerned with surveillance or privacy infringement.

What is a burner phone and how does it work? Here’s everything you need to know about burners and how to get one.

What is a burner phone?

A burner phone is a cheap prepaid phone with no commitments. It comes with a set number of prepaid call minutes, text messages or data, and it’s designed to be disposed of after use.

Burners are contract-free and you can grab them off the counter. They’re called burner phones because you can “burn” them (trash them) after use and the phone can’t be traced back to you, which makes them appealing to criminals. Burner phones are typically used when you need a phone quickly, without intentions of long-term use. 

Burners are different from getting a regular, contract-bound cellphone plan that require your information to be on file.

Why should you use a burner phone?

Burner phones are an easy way to avoid cellphone contracts or spam that you get on your primary phone number. Burners aren’t linked to your identity so you can avoid being tracked down or contacted.

You don’t have to dispose of a burner phone after use. You can add more minutes and continue using it. Burner phones can still function as regular phones, minus the hassle of a contract.

You can also get a burner phone as a secondary phone for a specific purpose, like having a spare phone number for two-factor authentication texts, for business or to avoid roaming charges while traveling. Burner phones are often used by anyone concerned with privacy.

Burner phones, prepaid phones, smartphones and burner SIMs: What’s the difference? 

Burner phones are cheap phones with simple designs that lack the bells and whistles of a smartphone. Because they’re designed to be disposable, you only get the essentials, as seen by the most common version, the flip phone.

All burner phones are prepaid phones, but not all prepaid phones are burners. What sets a burner apart is that you won’t have to give away any personal information to get one and it won’t be traceable back to you. Again, a burner phone is cheap enough to be destroyed after use.

Prepaid smartphones are generally low-end models. You can use any unlocked smartphone with prepaid SIM cards, essentially making it a prepaid phone.

If you want a burner, you don’t necessarily have to buy a new phone. You can get a burner SIM and use it with an existing phone. Burner SIMs are prepaid SIMs you can get without a contract or giving away personal information.

Where can you buy a burner phone?

Burner phones are available at all major retail outlets, including Best Buy, Target and Walmart. They’re also often available at convenience stores like 7-Eleven, local supermarkets, gas stations and retail phone outlets like Cricket and Metro.

You can get a burner phone with cash, and it should cost between $10 and $50, although it may cost more if you get more minutes and data. If you’re getting a burner phone specifically to avoid having the phone traced back to you, it makes sense to pay with cash instead of a credit card.

If you just want a prepaid secondary phone, you can use a credit card. Just keep in mind that credit cards leave a trail that leads back to you.

There are also many apps that let you get secondary phone numbers, including Google Fi and the Burner app. However, these aren’t burners necessarily because the providers typically have at least some of your personal information.
