2. Turn on the 5G switch to confirm whether there is 5G coverage in the current environment: Hello, the 5G network is in the early stage of development, and there is no 5G network coverage in most parts of the country. I suggest you consult the operator to find out whether there is 5G network coverage in your current area; Secondly, the operator's 5G network coverage is not perfect for some environments, and many indoor environments will not have 5G signal coverage. I suggest you change your environment to a stable coverage area of 5G network (such as outdoor) to see if 5G signals are displayed.
3. It is found in the operator's APP that 5G has covered the current area, but the mobile phone doesn't actually display 5G signal: Hello, the official apps of China Mobile, China Unicom and China Telecom can query the coverage of 5G network. If you find that your area belongs to the coverage area of 5G network, but no 5G signal is displayed, it is recommended that you further confirm the coverage area of 5G signal with the operator in the current environment.
4. Check whether the SIM card has arrears /SIM card restrictions: Hello, I suggest you consult the operator's customer service to find out whether the SIM card has 5G service or whether the SIM card has arrears. If the SIM card is in arrears, I suggest you pay the fee in time, restart your mobile phone and re-register the SIM card to access the network, and then check the signal display status.
5.5G base station opening time and the impact of adjustment: Hello, the 5G network is currently in the construction stage, and many 5G base stations will not be open all day. At the same time, operators will optimize and adjust the 5G network during the opening period. It is recommended that you consult the operator's customer service to find out whether the local 5G network is abnormal, which makes it impossible to register the 5G network.
