A: If your broadband and mobile phone number charges are tied, then you only need to check whether your mobile phone number is overdue. You can call the customer service number of the carrier to check the situation of mobile phone charges.

If the broadband is not bound with the tariff of the mobile phone number, in this case, you can also call the customer service phone of the operator and contact the manual customer service for inquiry. Note that when querying, you need to provide a broadband account, or handle a broadband ID number to query.

In addition, on the operator's APP, public number and other platforms, you can also inquire about mobile phone charges and broadband charges. Personally, I think calling the customer service number of the operator is the most convenient way.
