If you’re a GrabFood or GrabMart Merchant in Malaysia, you’ve probably heard that Grab is upgrading its merchant devices starting from December 2025.
Older models like Sunmi V2, V2s, and V2 Pro and V1s will no longer support the latest GrabMerchant app.
The new recommended device for all Grab merchants is the Sunmi V3 — the latest Android-based terminal designed for smooth order management, faster performance, and better reliability.
In this guide, you’ll learn everything you need to know about Sunmi V3 as a Grab Merchant Device — including setup, usage tips, troubleshooting, and where to buy it safely in Malaysia.
Why Sunmi V3 Is Now The Official Grab Merchant Device
The Sunmi V3 is the new generation GrabFood and GrabMart device, fully compatible with the latest GrabMerchant App (Android 11 and above).
With a 6.75” HD+ display, Octa-core CPU, and 3GB RAM + 32GB ROM, it delivers up to 3× faster app launch speed compared to older Sunmi V2 device.
Your GrabMerchant App can be easily downloadable from the Sunmi App Store.
Here’s what you can do inside the app:
View and accept new orders instantly
Pause or resume order taking during busy hours
Update item availability (e.g., sold out)
Access daily sales reports and statements
Check merchant settlement details (MSR)
Print receipts directly from the device printer.
All of this runs smoothly on Sunmi V3, thanks to its upgraded processor and memory.
