Operators update SMS reminders.

If your mobile phone number has paid the phone bill, but you still receive a short message reminding that the balance is insufficient, this may be caused by the following reasons:

1. The balance is not updated in time: some operators may delay updating the balance, and it will take some time to update the latest balance.

2. Delay in charge deduction: Sometimes the operator's charge deduction may be delayed, and it will take some time to update the latest balance.

3. Error in setting balance reminder amount: You may have set the wrong balance reminder amount, resulting in inaccurate SMS reminder. You can log in to operator official website or APP to check the correct balance and change the balance reminder amount.

4. Other expenses have been deducted: sometimes you may be deducted some unknown expenses, resulting in insufficient balance. You can log in to the operator official website or APP to check the detailed bill and find out the specific deduction.

If you still receive the SMS reminder of insufficient balance after removing the above reasons, it is suggested that you contact the customer service of the operator to consult the specific situation for more detailed help and solutions.
