How to check the number of short messages sent by Unicom card?

To check the number of messages sent, you can log in to Unicom's online business hall,/log in to your mobile phone number, and a new page will appear. You can click on the short message list, check the short message list of this month and the last five months, and see how many short messages you have sent. You can also call 100 10 to ask the manual service desk for help. If you have customized the monthly subscription of SMS, and the monthly subscription is not exceeded at present, the manual desk can't be found here. If the number of short messages you send has exceeded this month, the manual station can find out how many you have sent.
