After recharging, why didn't you receive the SMS prompt?

After the mobile phone is recharged, it will send a SMS reminder for free. If you don't receive the SMS reminder, you can check whether the current signal of the mobile phone is normal or pay attention to it later. Prepaid mobile phones can send "10 1" to 100 1 to check the real-time call charges. The prepaid mobile phone can send "102" to 1000 1 to check the balance.
