Is it effective to only receive SMS payment instructions?

Because when applying for a loan, the contract stipulated electronic delivery and left the mobile phone number, so the court will issue an electronic payment order, as long as the agreed mobile phone number is sent, it will be regarded as delivery.

Payment order is a legal document issued by the people's court to the debtor to pay cash and securities within a time limit according to the creditor's application, which saves the procedure of court trial and sentencing. The debtor shall pay off the debt within 15 days from the date of receiving the payment order and file a written objection with the people's court.
