Why doesn't Alipay use information to pay the phone bill?

Alipay did not receive the message on the mobile phone, and Alipay also showed the following reasons for the success of the transaction:

1. Maybe the transaction has been successful and the phone bill has been received, but the mobile phone has not received the information. You can call the operator's customer service phone with your mobile phone to check whether the phone bill has been received.

2. Maybe the phone bill has not been recharged. If the phone bill is recharged quickly, it will arrive in 10 minutes; If it is slow, it will arrive within 24 hours. You can wait and see if it will arrive late.

I hope my answer is helpful to you and can be adopted. Thank you!
