How long does Unicom reply to SMS when charging the phone bill?

Hello, it is timely to use the bank card to recharge in Unicom's online business hall, but there may be some delay due to network delay and banking system delay. It is recommended that you check the phone bill in time 10 minutes after the recharge is completed. In case of delay, the non-billing period generally does not exceed 24 hours at the latest, and the billing period does not exceed 48 hours at the latest. I hope I can help you.
