Precautions for installing broadband:
Broadband is usually connected with the mobile phone number. Unicom's number can't run the mobile network, and the mobile number can't run the telecom network. Therefore, in order to save time, you should determine your mobile phone number from the beginning, and then determine the supported operators according to the actual situation.
After the suit is selected, the installer will call you to confirm the installation time. What needs to be mentioned here is that in addition to the broadband package fee, there are additional installation fees, depending on the operator.
