WLAN can not be used for the following reasons: first, whether the function of the wireless network is turned on, second, whether the connection is connected, third, whether the correct password is entered, and fourth, whether the network signal is available.
First of all, the use of WLAN network and mobile phone is not related to whether the phone has no phone charges, we must first check whether the connection to the WLAN, if no connection, see whether the password is required, if no password is required to directly connect, if there is a password, you need to enter the correct password.
If your home network is not tied to the mobile phone bill, then you recharge the phone bill, the home network can not be used normally. It is necessary to pay or re-handle broadband network business separately.
If it is bound, then the charge to the account will generally return to normal within 30 minutes, you can check whether the router line in your home has been disconnected, some mobile phones need to reconnect to the network to normal use
Using wlan means using WiFi. This is not directly related to whether you have a mobile phone card installed in your phone, or whether you have a recharge charge, as long as there is a suitable WiFi in the room should be able to use. He said that he could not connect to WiFi, indicating that there is a problem with the WiFi function of your phone itself.
Under normal circumstances, even if the smartphone is not installed mobile phone card, as long as the wlan click to select the appropriate WiFi network, enter the WiFi password, you can surf the Internet.
First of all, I did not understand whether the WLAN you said could not be used is the router at home can not be used or the mobile phone hotspot can not be used. If the mobile phone hotspot can not be used, it is not necessarily due to arrearage, it may be the mobile phone problem. If the home router can not be used, you can put the router aside directly to the Internet line, if not, contact the engineer, if the line indicates the router problem, check the Settings or replace it.
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
