What does it mean to send a text message or call to remind customers when natural gas is overdue?

If you owe money, you must stop the payment before the deadline and the payment will be made again. If you don't pay the payment after the deadline, it's overdue and you have to pay a late fee. If you don't pay, the gas company will turn off your gas. Tell the gas company where you are after paying the fee. If it is overdue, it will pay liquidated damages, which cannot be reduced. According to Article 30 of Chapter 5 of the Measures for the Administration of Urban Gas, gas users shall pay the gas fee on time. If the payment is not made within the time limit, the gas supply enterprise may, from the date of overdue, impose a late fee of 1%-3% on the gas fee payable to the users who have not paid the gas fee. If the circumstances are serious, gas supply can be suspended.
