Tecno just unveiled a rather intriguing at MWC 2026. The standout feature here is likely the size. Most modular smartphone concepts start bulky and only get bulkier once attaching accessories. Tecno’s base smartphone is just 4.9mm thin, which is significantly thinner than a pencil .
Of course, the size increases with each attached module. However, snapping on the power bank module makes the thickness comparable to a standard modern smartphone. Another key feature here is how these various modular components stick together. Tecno has developed new interconnection technology that uses both magnets and pin connectors. This should make it easy to both attach and remove components.
The company says this phone has been designed to grow with the user through hardware expansion. To that end, Tecno has developed 10 modules. There are various camera lenses and something that looks like a dedicated gaming controller.

While the magnets are for attaching, the pin connectors assist with power delivery. Data transmission between the phone and the modules is handled wirelessly, with the ability to switch between Wi-Fi, Bluetooth and mmWave depending on where the user is located.
There are two colorways for both the phone and the ecosystem of accessories. There’s a silver-aluminum edition and a nifty-looking grey version. This doesn’t matter to actual consumers because, well, it’s just a concept design. It does look like the company’s magnetic attachment technology could make it to some actual products down the line.
Tecno has always been a company that marched to the beat of its own drummer. It has developed a , a model with a and a foldable with a .
The industry hasn’t quite embraced modular smartphones just yet, even though there have been some nifty concept designs. Google’s goes back more than a decade, and the same can be said of that never saw the light of day.
There have been some modular phones released to the real world, but they weren’t nearly as ambitious as Tecno’s concept. LG launched a semi-modular phone , but it . Moto has also released a , but they didn’t set the world on fire.
