Will it be fraud to receive a dunning call from her husband's online loan?

This is the general way for small loan companies to collect money, because when your husband applied for a loan, the emergency contact gave the loan company his mobile phone number, and their salesman would send a text message to his friend on his mobile phone to collect money. The situation now is to communicate with your husband, if it is not your husband's debt. If there is no loan, it should be fraudulent phone calls, blackmailing or calling the police.
