ARTICLE – Modular phones have been tech’s favorite broken promise for over a decade. Google tried it with Project Ara. LG had a go with the G5. Motorola came closest with Moto Mods. Every time, the idea sparked genuine excitement before fading into the “maybe next time” pile. TECNO apparently didn’t get the memo.
The company showed up to MWC 2026 in Barcelona with the wildest version of the modular phone yet, and our team got hands-on time with it at the show. At 4.9mm thin, the base phone is slimmer than a pencil and a good deal thinner than Apple’s iPhone Air. You pick it up and instantly wonder how they fit a screen and battery inside something this flat. The trade-off is a 3,000mAh battery and a single rear camera in the base unit, both designed to be expanded through modules.
That module ecosystem is the real story. TECNO calls it Modular Magnetic Interconnection Technology, which is a mouthful, but the execution is surprisingly simple. The back of the phone has a magnetic array that lets you click modules into place with a satisfying snap. Need more battery? Slap one on. Want a better camera or a game controller? TECNO built modules for both, with camera options ranging from a 50MP sensor to a 200MP module with a periscope telephoto. Ten total, and the fun part is they stack. Put a battery on the back, then a speaker on top of that. It’s like building with LEGO, except every block does something useful.
The thinness isn’t a gimmick
There’s a practical reason TECNO started this thin. Every module adds bulk, and if you started with a phone that’s already 8 or 9mm thick, stacking a battery and camera module would turn it into a brick. Starting at 4.9mm means even with the 4.5mm power bank module snapped on, the total stays close to a normal smartphone. It’s smart engineering dressed up as a party trick, and it works better than you’d expect.
There’s no USB-C port anywhere on the phone. Charging and data both happen through the module system, which is a bold move even for a concept. The connection uses magnets for physical grip and pogo pin connectors for power. Data moves between modules wirelessly, switching between Wi-Fi, Bluetooth, and mmWave depending on what each module needs. A power bank or game controller can run on Bluetooth alone. Camera modules that need to stream a live preview tap into Wi-Fi or mmWave for faster speeds. That wireless approach keeps things clean and avoids the tiny-port frustration that killed earlier modular attempts.
The phone comes in two versions: the Atom Edition in silver with red accents, and the Moda Edition in darker gray with gold details. Both look polished enough that you’d want to carry the phone bare. That matters more than it sounds. Previous modular phones always looked half-finished on their own, like they were missing something. TECNO’s concept looks complete with or without modules on the back.
If you look closely at the Atom, you’ll notice it has a single set of power connectors. The Moda has two, which hints at different levels of module support depending on which direction TECNO takes this. It’s a small detail, but it tells you the company is already thinking about how to tier the experience for different users. That kind of forward planning is something earlier modular efforts never quite got right.
Why this one feels different
TECNO’s approach borrows the best lesson from Motorola’s playbook: make the modules easy to attach and remove. Where it improves on the formula is the sheer thinness of the base phone and the stacking capability. The ability to layer modules on top of each other opens up combinations that previous modular systems never considered. You’re not picking one accessory and committing to it for the day. You’re mixing and matching based on what you need right now.
TECNO borrows the best lesson from Motorola: make modules dead simple to attach and remove. Where it pushes things forward is the stacking. You’re not picking one accessory and committing to it all day. You mix and match based on what you need right now, and the slim base means adding two modules still keeps the phone pocketable. We got hands-on time with it at MWC, and attaching new modules felt genuinely easy and fun in a way that previous modular phones never managed. That wasn’t lost on the crowd either, with TECNO’s booth drawing a steady stream of people testing every combo they could think of.
The honest caveats
This is a concept, not something you can buy. TECNO hasn’t shared a price, a release date, or even a firm promise to bring it to market. The company says the phone was built to grow with users through hardware expansion, which could mean “shipping next year” or “cool demo, see you never.”

The company says the phone was designed to grow with the user through hardware expansion, which is the kind of language that could mean anything from “shipping next year” to “cool demo, see you never.”
There’s also a trust gap. Motorola supported Moto Mods for years, which gave buyers real confidence that their accessories wouldn’t turn useless overnight. TECNO doesn’t have that track record. Modular add-ons only make sense if the company making them sticks with the form factor long enough for people to actually invest.
There’s the trust factor to consider as well. Motorola supported its Moto Mods ecosystem for years, which gave buyers confidence that accessories wouldn’t become obsolete overnight. TECNO doesn’t have that track record yet, and modular accessories are only worth investing in if the manufacturer commits to the form factor long-term.
TECNO’s MWC wasn’t only about modules
The modular concept got the biggest crowds, but TECNO filled its booth with other attention-grabbers too. The Pova Neon concept uses ionized inert gas sealed inside a chamber on the rear panel. The result is random lightning-like patterns that shift and change with every glance. No two are the same. It’s pure spectacle, the kind of thing that stops foot traffic dead on a packed show floor. Whether it actually makes the phone better is up for debate. As a conversation piece, though, it earns its spot.
TECNO also launched a Tonino Lamborghini partnership with the Pova Metal Tonino Lamborghini Limited Edition, a full-metal unibody 5G phone with a glowing rear element and luxury branding. The collaboration extends beyond phones to laptops, tablets, and earphones. It’s part of a broader pattern at MWC 2026, where nearly every phone brand brought a luxury car tie-in to the show floor.
What this means for the rest of us
Nobody is buying a TECNO modular phone tomorrow, and the realistic odds say this concept stays a concept. But the core idea is worth watching. A phone thin enough to serve as a foundation for stackable magnetic modules solves the biggest problem past attempts couldn’t crack: keeping the base device pocketable while still leaving room to build.
What sets this apart isn’t any single feature. It’s how thinness, stacking, and snap-on simplicity come together in a way that Project Ara and Moto Mods never managed. TECNO found a formula that makes the idea feel genuinely fun again, which is more than anyone else has pulled off in years. Whether fun is enough to build a real product around is the question they still have to answer.
For now, it’s one of the most entertaining things on any booth floor at MWC 2026. Sometimes that’s enough to get the right people paying attention.
