The Nokia 3510, a sleek and compact candy bar phone, was designed for basic communication and messaging needs. It featured a monochrome display, a simple keypad, and a built-in antenna. The phone's highlight was its user-friendly interface and intuitive design, making it an ideal choice for first-time mobile phone users.

The phone's design incorporated a unique slide-out keypad that revealed the main display and control buttons, adding to its stylistic appeal. While the 5300 offered a wider range of features than the 3510, its focus on multimedia functionality and its relative affordability made it a popular option for individuals seeking a phone that offered both communication and entertainment capabilities. Both the 3510 and 5300 contributed to Nokia's dominance in the mobile phone market during their respective eras.
