SUNMobile

CSL Limited operates a significant mobile network in Hong Kong under several brands, including 1O1O, One2Free, New World Mobility, and SUN Mobile. As a key player in Hong Kong's vibrant telecommunications market, CSL provides a range of services to both consumers and businesses. It is one of the major networks alongside others like SmarTone and HKT (PCCW Mobile), contributing heavily to the city's high mobile penetration rate. Understanding these networks often requires knowing their assigned identifiers, and CSL’s presence is easily identifiable by its Mobile Country Code (MCC) of 454, representing Hong Kong, and its Mobile Network Code (MNC) which is 0. Hong Kong, located in Asia, possesses a sophisticated mobile infrastructure landscape. CSL's various brands cater to different segments of the population, from premium users seeking advanced features with 1O1O, to budget-conscious subscribers through SUN Mobile. CSL was one of the first to introduce 5G to Hong Kong. Spotting an MCC of 454 paired with an MNC of 0 on your mobile device indicates you're connected to CSL's network in Hong Kong, a country known for its efficient and cutting-edge communication systems. This MCC/MNC combination is crucial for network operators and subscribers alike for identifying regional service providers.
