The dumbphone trend has been quietly building for a few years now, and the Sidephone SP-01 is one of the most ambitious entries to date. At $249, it promises a modular, distraction-free phone that you can actually customise with swappable keypads. The idea is genuinely interesting. The execution, at least right now, is more complicated than the concept lets on.
It runs Android 12 under the hood, though you would barely know it. Google services are gone, the Play Store is gone, and getting new apps onto it involves sideloading or scanning QR codes to pull from Sidephone's own App Library. The modular bottom plate is the real talking point, and it works well once you get there. But getting there takes patience, and not everyone looking to simplify their digital life wants to spend an afternoon tinkering before they can make a phone call.
- Modular bottom plate swaps between a T9 keyboard, the Sundial music controller, and more to come.
- Runs AOSP Android 12 with no Google services. Apps require sideloading or Sidephone's own App Library.
- Setup is not beginner-friendly. Modules need QR scanning and app integration before they work.
- 2.8-inch touchscreen, 4GB RAM, 64GB storage, 2000mAh battery, 13MP rear camera.
- No NFC, no headphone jack, no wireless charging, no microSD slot.
- Best suited to tinkerers and people serious about cutting screen time. Not a casual purchase.
The Design and Modules
The SP-01 is a small phone by modern standards. It is 5.5 inches tall, weighs less than 5 ounces, and fits comfortably alongside keys and a wallet. The top half houses a 2.8-inch IPS touchscreen running at 480x640, which is genuinely small in 2026, though that is partly the point. Below it sits a USB-C port, SIM tray, volume and power buttons, and a rear loudspeaker. The plastic body feels functional rather than premium, and the camera is notably low quality for real-world use.
The bottom plate is where it gets interesting. Keypads attach using magnets and micro-latches, snap in without tools, and can be swapped without powering the phone off. The Classic T9 keyboard ships in the box and uses predictive text to get through messages. The Sundial module is the one that catches the eye though — nine reprogrammable buttons designed around music playback, built to feel a bit like an old iPod click wheel with its own personality. A QWERTY module is also in the works. The swappable system works well physically and gives the SP-01 a genuine point of difference in the dumbphone space.
Setup and Software
This is where reality sets in. The SP-01 does not run Google's version of Android, and there is no Play Store. Sidephone ships with a curated set of essentials including WhatsApp, Maps, and Uber, and you access additional apps through the App Library using App Packs accessed by scanning a QR code. If you want something outside that list, you are sideloading it manually.
The modules also require their own setup steps. Each one needs a QR scan, a companion app download, and integration before it functions properly. None of it is impossible, but for a device marketed at people who want less friction in their phone life, there is a fair amount of friction in getting started. Once it is all configured the experience smooths out considerably, but that first hour or two is a barrier that will put some people off entirely.
Battery, Camera, and the Basics
Battery life is one of the genuine highlights. Verizon rated it at up to eight days with calls and messages as the primary use, though real-world use with apps running will cut that closer to four. Either way, it comfortably outlasts any flagship Android or iPhone, which is exactly what you want from a phone built around doing less.
The 13MP Samsung ISOCELL 3L6 camera with autofocus sounds reasonable on paper, but reviewers have been consistently clear that real-world output is well below what the spec suggests. It is usable in good light for quick snaps, but if photography matters to you at all, this is not the phone for it. There is no front camera either, so video calls are out entirely. No NFC means no contactless payments, which will be a dealbreaker for some. And with no headphone jack and no wireless charging, you are also relying on USB-C for everything audio and power related.
Who Is This Actually For
The Sidephone SP-01 is not a phone for everyone, and it does not pretend to be. The founder's stated goal is reducing distraction through hardware choices rather than willpower alone, and the device makes a reasonable case for that approach. Physical keys naturally slow you down. The small screen discourages endless scrolling. The absence of social media apps removes the temptation at the source rather than relying on app timers and focus modes that are easy to dismiss.
Where it works best is for someone who already knows what they want: a secondary device to carry when they want to disconnect, or a primary phone for someone technically comfortable enough to enjoy the tinkering that comes with it. If you are expecting a polished out-of-the-box experience similar to a Light Phone or even a budget Nokia, you may find the SP-01 frustrating. If you enjoy configuring hardware and the idea of a phone that grows with new modules genuinely appeals to you, it is a compelling first-generation device with clear room to mature.
- Modular keypad system is genuinely clever and well-executed physically
- No Google services, no algorithmic feeds, no distractions baked in
- Battery life comfortably hits multiple days of real use
- Small and light enough to actually change how you carry a phone
- AOSP base means capable hands can customise it further
- Setup is far too complicated for the audience it is targeting
- Camera output is well below what the spec sheet suggests
- No NFC, no wireless charging, no headphone jack, no microSD
- Sideloading apps is not a beginner-friendly experience
- $249 is a tough ask for a plastic body at this stage of development
