In 2004 New World Development started to own the MNO via another listed intermediate holding company New World Mobile Holdings. Previously, New World PCS Holdings, the direct parent company of New World PCS, as well as New World Telecommunications, were sister companies that under the same direct parent company New World Telephone Holdings, which in turn it was owned by New World Development.
In 2006, NWPCS merged with Hong Kong CSL to form CSL New World Mobility, an intermediate holding company that was owned by Telstra (76.4%) and New World Development (23.6%). It is no longer the direct subsidiary of New World Mobile Holdings Limited and New World Development.
In 2008 New World PCS Limited was renamed to CSL Limited, with the old CSL (Hong Kong CSL Limited) became its subsidiary. However, the brand New World Mobility was still used by the group in the same year (used by New World Mobility Limited, a joint venture of CSL Limited), which eventually became Sun Mobile in 2014.
