Hello, everyone. I can't find the record of the text messages I received. Who should I call to handle it?

Telecom has opened an online business hall/login/,and logged in with the mobile phone number and the random password obtained by the mobile phone. You can see the detailed list of voice, data, SMS, value-added services, broadband and other services in "Self-service"-"Expense Inquiry"-"Detailed List Inquiry". I hope it works for you.
