The concept of a modular smartphone has been pitched many times, but alas, it was not to be. What? You said Fairphone? True. Fairphone kind of achieved modularity, but not the way Google Project Ara and Moto Z pitched it. Those ideas were about snapping on a function when you need it. Fast forward to 2026 at MWC in Barcelona, TECNO revisited the concept with its Modular Magnetic Interconnection Technology.
The idea is simple enough: allow smartphones to expand or change their capabilities through magnetically attached hardware modules. The goal is to keep phones slim for everyday use while allowing additional hardware to be added when needed or removed when not required. That means it is basically a use-based device, where it can be adapted to the user’s specific needs for a given situation.
The magnetic modular architecture is built into the back of the phone. The rear panel contains a precision magnetic array and pogo-pin connectors that allow hardware modules to snap on securely. These connectors provide power and data transfer, while wireless connections like Bluetooth, Wi-Fi, and mmWave help synchronize the modules with the phone.
The base device is crazy thin—around 4.9 mm thick—and super lightweight (I am not sure if the weight was revealed). On days when you only need the basic functions like Internet and communications, it stays ultra-thin and light. But when you need to head out for longer periods of time, you can stack a couple of battery modules onto it. Need long-range imaging? Attach the telephoto camera lens module. Want to record your adventure? The action camera module has you covered.
It does not stop there. Perhaps you game more. Or maybe you need more storage or better connectivity in the wilderness. The gaming controller grip, external storage, and connectivity modules cover those scenarios, too. The telephoto attachment even has its own sensors, by the way. The phone simply serves as the viewfinder.
I think you get the idea.
Thanks to advancements in connector and magnetic technology, TECNO may just succeed where others have failed. But why revisit a concept so many have tried and failed before? TECNO believes that as more capabilities and advanced hardware are introduced, phone sizes will inevitably grow. The idea here is to welcome new capabilities while keeping the base device slim, or perhaps even smaller.
I mean, we do not need every feature all at the same time, so it kind of makes sense.
At Barcelona, TECNO presented two versions of the concept device: the ATOM Edition and the MODA Edition. The former adopts a minimal, structured design philosophy, while the latter takes on a more expressive, tech-centric aesthetic.
But before you go all ga-ga over this modular smartphone tech, you should know that it is still a concept. Whether it will ever become a real product remains to be seen.
