You may have heard the term «burner phone» and didn’t think you’d ever need one because (a) you’re not involved in crime or espionage or (b) engrossed in watching TV shows that involve both. However, if you’re traveling out of the US and coming back in, you might want to be carrying a phone that doesn’t include all your personal correspondence.

That’s due to increasing reports that agents of US Customs and Border Patrol are scanning mobile devices and, according to some reports, turning people away or confiscating phones based on free-speech opinions they discover. In one case, a French scientist entering the US for a conference was reportedly detained and denied entry after messages critical of the Trump administration were found on his phone. It’s unclear how widespread these phone searches are or if people are being stopped for other reasons.

Although carriers have offered prepaid phones since the ’90s, the term burner phones or «burners» essentially became popular in the 2000s due to its use in the celebrated HBO series The Wire, in which characters used burner phones to avoid getting caught by the police. Although often portrayed as such, burners are not only meant to be used by criminals. With privacy concerns rising, you might consider using a burner phone yourself.

So, what exactly is a burner phone, and how does it work? Below, we explain everything you need to know about burners and how to get one.

What is a burner phone?

Simply put, 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 is 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, i.e., trash them after use, and the phone cannot 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 usage. 

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

Why should you use a burner phone?

Burner phones are an easy way to avoid pesky cellphone contracts or spam you may be getting on your primary phone number. Burners are not linked to your identity, so you can avoid getting tracked down or contacted if that’s what you need.

However, you don’t have to dispose of it after use — you can just add more minutes and continue using it. Burner phones can still function as regular phones, minus the hassle of getting a phone with 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 purposes or to avoid roaming charges while traveling. You can get a burner phone for any privacy reasons you may have.

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

Burner phones are typically cheap feature phones and usually don’t come with the bells and whistles of a smartphone. Since these are designed to be cheap and disposable, you only get the essentials and very simple designs. The flip phone is a common sight in the burner phone market.

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

Prepaid smartphones are generally low-end models to begin with, and burners are the cheapest prepaid phones you can get. However, you can use any unlocked smartphone with prepaid SIM cards if you want to, essentially making it a prepaid phone.

If you want to get 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 as well. 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 the major retail outlets. You can pick them up from Walmart, Target, Best Buy and other big retailers. They’re also often available at convenience stores like 7-Eleven and Rite Aid, local supermarkets, gas stations, and retail phone outlets like Cricket, Metro and others.

You can get a burner phone with cash; a typical burner should cost between $10 and $50. It may cost more if you get more minutes and data with the phone. 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 pay for one with a credit card. Credit cards will leave a paper trail that leads back to you, but that shouldn’t be an issue unless you really don’t want the burner phone linked back to you.

There are also many apps that let you get secondary phone numbers, including Google Fi and the Burner app. However, these cannot quite be called burners in the ideal sense, since these providers will typically have at least some of your personal information.
