Why did China UnionPay Express pay by mobile phone successfully, but there was no consumption record and prompt tone?

Because of bank balance change, SMS reminder delay, or SMS platform failure.

I can't receive the information in time. Not all bank SMS reminders can be received, and there are delays or platform failures.
