Why do you want to send a text message to remind me that my mobile phone is in arrears, because it is going to stop?

This is caused by deducting the monthly rent at the beginning of the month. If the balance of your phone bill is greater than 10 yuan before deducting the monthly rent at the beginning of the month, the operator will generally not remind you. But at this time, if the available balance of your mobile phone number is less than the monthly rent, it may lead to the arrears of your mobile phone number after deducting the monthly rent at the beginning of the month.

I hope my answer can help you. I hope it can be adopted. Thank you.
