The J750's small size and plastic build, it feels reasonably solid. The spring-operated slider is sturdy and smooth, while the keypad and controls feel firm and comfortable. A five-way navigational pad and two selection buttons handle the grunt of the work, while the slightly raised keypad makes SMS messaging a breeze.

Despite being a relatively inexpensive handset, the J750 has a reasonable features list. Apart from a fairly standard 1.3-megapixel camera, a front-mounted VGA camera handles video calls over a 3G network on the 2100MHz band. Call quality is a mixed bag — conversations aren't as clear as we'd have liked, though volume is quite loud and is reasonable enough to conduct a call in a noisy environment.
