How to see who you are texting in the online business hall?

I have no idea who you are. If you are a GSM user, after logging in to the online business hall, you will see a "phone bill service" in the lower right corner and click "More". When a new webpage comes out, click "Details of the current month" and a "secondary authentication" will come out. You click "get the random number of SMS". This is to send the secondary authentication password to your mobile phone through random SMS (you must hold the mobile phone). After entering the random code of SMS, click "Advanced Query" and click "SMS List" in the third box!
