Is it illegal to send text messages to loan guarantors?

As long as it is a formal way, it is not illegal.

The loan guarantor refers to the behavior that the guarantor and the creditor agree that when the debtor fails to perform the debt, the guarantor will perform the debt or assume the responsibility according to the agreement. Choosing to be a guarantor needs to consider certain consequences.

Individuals must think carefully before being loan guarantors. Once a guarantor has signed a letter of guarantee, it is a guarantor, unless the lender is approved by the lending institution to cancel the guarantor qualification. Even if the relationship between the guarantor and the debtor changes, such as the husband as the guarantor of the wife's loan, even if the two eventually divorce, the guarantee will not be affected by the dissolution of the marriage relationship and will still be valid.
