China Telecom-1599 Do smart families need to pay extra diplomatic fees every month?

According to the information you provided, China Telecom 1599 Smart Family Package will be returned on a monthly basis, with a minimum monthly consumption of 129 yuan. If your phone bill balance is not enough to cover the minimum monthly consumption, you may have to pay extra fees.

If you have already paid the smart family package fee of 1599 yuan, and included the minimum monthly consumption of 129 yuan, there is no need to pay extra fees in general. However, if your usage exceeds the minimum monthly consumption, such as the call duration and traffic included in the package, you may have to pay extra for the excess.

I suggest you check your phone bill, understand the monthly consumption, ensure that your account balance is sufficient, and avoid arrears.
