My mobile phone is almost out of balance, why didn't I receive the SMS prompt?

In order to ensure the normal communication, when the balance is insufficient, our company will make a friendly reminder of the phone bill through SMS/voice. However, when the mobile phone is turned off, out of service area or busy, it will lead to the inability to receive SMS or voice reminder in time.
