Is there any room for Unicom 4G?

If you put the USIM card of Unicom's 4G package on a mobile phone that supports Unicom's 4G network, and your area has covered Unicom's 4G network, you can use Unicom's 4G network. According to the situation you described, there is no 4G network. Maybe your mobile phone doesn't support Unicom 4G, or your location doesn't have 4G network coverage. If the above situation has not been solved, it is suggested that you can contact the local manual customer service for handling.
