"I only ever cross borders with a blank phone because I don’t want you invading my privacy" is a perfectly valid answer. You can also add that it is your employer’s policy and/or your government official recommendation.

You can also point out that other countries want to search phones too.

"I have to do this because of country X, you know that they're like, amirite?"

> a perfectly valid answer

Makes no difference at all in the real world. You don't have to give valid answers, you need to get the guy across from you to not find you suspicious. That phrase is going to put a red flag on you, valid or not.

> you need to get the guy across from you to not find you suspicious.

What? No, who cares about that? Let him find you suspicious, what matters is that he doesn’t access your data. And it is not suspicious to cross borders (esp. US borders) with burner phones. As others have said, it is standard practice.

He doesn't access your data. He confiscates your phone, then still doesn't access your data, then denies you entry, then still doesn't access your data, then holds you in immigration detention for a week while he tries to access your data, which he can't. Is that a success? Maybe, if your data really is that valuable and a successful border crossing isn't.

> Is that a success?

Definitely.

> Maybe, if your data really is that valuable and a successful border crossing isn't.

Even if my data consisted entirely of cat pictures, it would be more valuable than successfuly crossing the border into a country that actively tries to invade my privacy.

Well why are you showing up at a border crossing if you don't want to cross the border?

You may wish to cross the border but not at all costs.

It's one that will get you denied entry, or detained indefinitely.

I have worked for employers that required taking a burner phone to certain countries without any accounts logged in, etc. (so mostly for calls, maps, and web browsing) and nobody has ever been detained or denied entry. Some countries know that this is just standard procedure when they are visited for business trips. Probably different for the US though.

(Not legal advise of course, just observation. Always check with the legal department of your employer, etc.)

> Probably different for the US though.

After cornering themselves into being labeled an unsafe destination (long overdue imho), the US are gonna have to learn being treated as such.

"I'm here for business and my employer requires it" is an acceptable excuse. "I don't like government surveillance" is not.

"I'm self-employed and my SOC 2 compliance consultant requires it."

Denied entry, why not. But detained?

In the USA border they detain people they think are lying until they think they are not lying.

Lying about what? "I only bring a burner phone to border checks because I don’t want people like you to access my data“ is not a lie, and I fail to see how it could be interpreted as such.
