There is no SMS prompt for Alipay to pay the phone bill.

There are two kinds of mobile phone recharge charges: first, there are charges for mobile phones with balances, that is, they can recharge without stopping, so that they can receive short messages. However, if you choose to charge slowly for 48 hours, it may be that the phone bill arrives slowly, so the time to receive the text message will be delayed, but you will receive the text message as soon as the phone bill arrives.

Second, the mobile phone has been in arrears. In this case, if you recharge your phone, you won't receive the SMS.
