When we used the mobile phone bill, there was a situation of arrears, and the mobile phone wireless network was not available at this time. But after we pay the fee and make up the arrears, we still can't use the wireless network.
First we can wait a few minutes and try again later. Another way is to restart the phone and log in again. If you still can't, you can call Unicom customer service phone for manual consultation
Yes, Unicom connection WIFI is the official connection that requires login authentication, WIFI is required. Personal identity registration as well as practical.
