Founded in 2015, NOMU has taken the job of manufacturing solely rugged smartphones very seriously. According to the OEM, whose base is in Hong Kong in China, its phones have won high recognition and trust of the customers in the last two years due to super strong protective function, premium manufacturing technique, and distinctive appearance.
The NOMU S30 Mini was released in 2017 and is one of the best (rugged) smartphones from the OEM. Given the relative success and acceptance of other phones from the OEM, like the NOMU S20, NOMU S30, and NOMU T10, I guess we can trust NOMU on this one; the S30 Mini.
