Why didn't Unicom reply to the message when it inquired about the traffic balance?

If the traffic information can't be replied by SMS, it doesn't rule out that too many people have used the delay system. It is recommended to wait patiently for the SMS reply. You can also check whether the short message interception function is set, which causes the short message information not to be received normally. It is suggested that you can also check the traffic usage of Unicom's mobile phone number through the following channels:

1. Log on to the home page of Unicom's online business hall, and click phone bill query > usage query > Internet traffic to query the usage of mobile Internet traffic.

2. After logging in to the client of the mobile phone business hall, click "Internet Traffic" to query the current month's mobile phone Internet traffic.

In addition to the above methods, you can also call the local manual customer service hotline or go directly to the local Unicom's own business hall to check the mobile phone traffic.
