Conclusion
The Plum Optimax 7.0 is a quintessential budget device from 2016, aiming to provide essential smartphone functionality combined with a large display at a highly accessible price. While it delivers in areas like battery standby time and dual SIM availability, it is not designed for high-performance needs or multimedia excellence. As a discontinued model, it may still interest collectors or those specifically seeking a simple, large-screen solution for standard communication tasks.
