Check the phone bill. Can you send a text message? My mobile phone is connected.

Unicom mobile phone supports phone bill, call record and SMS query, but does not support SMS content query.

The content of SMS is user's privacy, and Unicom will not save it.

Unicom users can log in to the online business hall/homepage with their mobile phone numbers, click "phone bill inquiry" > "phone bill inquiry", and select the details to be inquired (such as call details, SMS details, value-added services details, Internet traffic details, WLAN details, etc.). ) Inquire about your detailed information in the last six months (including the current month).
