Hi, as the router is just a tool to help you to get internet access for your home devices, which is not the internet source or a modem, so you may need to get a modem and subscribe to internet service. Or you may have to return the product.

It is sincerely suggested to contact the TP-Link local support for a detailed pre-sales consultation. They should speak or write non-English, which maybe better for you to understand.
