We’ve Been Hunting for This Phone for Over 3 Years

Most “dumb phones” on the market today aren’t actually dumb at all.

Think about it: that basic flip phone you thought would protect your privacy? It’s nearly guaranteed to be running software controlled by either Google or Chinese manufacturers. You escaped the smartphone surveillance trap, only to walk into a different kind of digital cage.

That’s exactly why we’re excited to offer the Sunbeam Wireless F1 Pro Series.

We’ve tested these devices and have fallen in love with them. These are the first flip phones I’ve been genuinely excited about in years.


Here’s What Makes These Different

While other companies slap together basic phones with whatever operating system they can license cheaply, Sunbeam Wireless took a completely different approach. They built BasicOS – their own custom fork of the Android Open Source Project.

Translation: No Google. No China. No data harvesting. Just a phone company in Memphis, Missouri that believes your privacy shouldn’t be for sale.

Think of BasicOS as the GrapheneOS of flip phones – modern functionality with complete control over your digital footprint.


Meet Sunbeam Wireless

Founded by Sterling Martin and Nelson Hoover in Memphis, Missouri, Sunbeam Wireless was created specifically to counter the tech industry’s relentless push toward digital addiction. While other companies ask “how can we get users to spend more time on their devices?” Sunbeam asks “how can we help people reclaim their time and attention?”

As someone who’s spent years helping people escape Big Tech surveillance, I’ve watched too many people trade their smartphone for a flip phone that still tracks them. Sunbeam Wireless gets it. They’re building phones for people who want technology to serve them – not the other way around.

This is intentional technology choice, not technological compromise or regression.
