> Oh, they may well give you bad time if your phone looks like a burner with too little content.

Issuing 'burner phones' and laptops to staff visiting countries such as China or the USA is now SOP for many companies handling sensitive data, including mine.

Don't think this isn't unusual.

This is not... advice. But if anyone's actually going to do this, the method that's worked for me...

A couple weeks before your trip, factory reset whatever burner phone you're planning on using and swap your SIM card over. Install a few basic apps you wouldn't mind them looking through. Enable hotspot/tethering, and connect your other phone via Wi-Fi.

For a couple of weeks, use the burner as much as you can with what is available on it. When you're driving, us the maps app for GPS. Make and receive some calls, ignore some spam calls. Read the news. Get a few inane text messages conversations going, etc.

When you travel, leave your regular phone at home and take the burner. When it's searched at the border, it has enough activity to pass most initial smell tests. If asked, you dropped your other phone and didn't have time to get it fixed before your trip, this is one a friend lent you.

This has worked for me. Never _actually_ into anything illegal, but just apparently had a suspicious vibe about me or something because every time I crossed the border into or out of the country I was spending 4-5 hours getting searched. Didn't need someone going through my entire life going back decades every time--once was enough.

If you are a citizen it doesn’t matter. They have to let you in.

If you are a citizen like this person is then you can tell them to fuck off, they can keep the phone, and they have to let you in.

They won't unless you are already on "their list" My phone basically looks like a burner phone, I do not use social media, do not install apps, my iphone fits (with room to spare) all "apps" on a "single page." I just call and text from my phone and have a browser and maps and that is basically it.

Years ago I chatted with a border guard from another country about their job (while they were not working). Not having a phone nowadays would be considered "strange" enough to flag you. If you're not a citizen of said country, it could even dramatically increase the odds of disallowing you entry. Often this would prevent you returning for a set number of years.

At the end of the day, it's always best to just not have anything "bad" on your devices. People have been caught up for all numbers of "innocent" reasons (pictures of their kids in the bathtub, ancient photos in their albums of themselves doing illegal things such as drugs or underage drinking, text messages or browser history disparaging politicians the border guard may support, porn in your history) that can give a border guard in a bad mood good reason to ruin your day.

I personally don't want my phone data hoovered in and analyzed or marked, even though I don't really have anything to hide. I don't care enough to do anything about it, but if I did I would probably have a second travel phone with a curated amount of data, apps, accounts, etc.

The last time I tried to do that on a trip to Germany, admittedly many years ago, I found I could not get phone service without a local address.

If you can, just avoid ever entering the US at all.

It has been standard practice for some time now in some European companies.
