10658666 Is there a charge for sending text messages with this number?

I don't know what card the landlord used, mobile? Unicom or PHS? Call customer service to ask if you have ordered any website services. Some websites like this are free, but they may disappear after a period of time. However, some websites are outrageous. Consumers don't cancel on their own, and they will charge after a while. Or, type in the bill of the current month to see if there are any unknown charges, which is called charging on behalf of the mobile phone. If there is a charge, you can complain directly by phone, and it is not difficult to get the charge back.
