The single network and full network versions of the 4G version of the Newman vehicle can be distinguished by the network frequency band. The single-network version only supports certain network bands, usually those of the major carriers in the country, such as China Mobile, China Unicom or China Telecom. The full network version supports a wider range of network bands, including those of multiple carriers at home and abroad, which can be used globally. To distinguish between the two versions, check the vehicle's product manual or consult the vendor to confirm the range of network bands it supports.
