How to contact customer service without Unicom card service?

You can contact Unicom customer service in the following ways:

1. Call Unicom's customer service hotline: 100 10. After dialing, please follow the voice prompts to select related services, and then communicate with the customer service staff.

2. use the Unicom mobile phone business hall App. You can download and install the Unicom mobile phone business hall App, and consult and communicate with customer service staff through online customer service functions.

3. Online consultation. You can log on to Unicom official website or Unicom WeChat official account, and click the corresponding online customer service button to communicate with customer service staff.

If your Unicom card has no service, there may be the following reasons:

1. Regional signal problem: It may be that the signal coverage at the current location is poor or there is no service due to signal interference. Try changing the location and try again.

2.SIM card failure: There may be something wrong with the SIM card. Please try inserting and unplugging the SIM card again, or replace it with a new SIM card and try again.

3. Illegal use leads to downtime: If your mobile phone card is down, it may be because your mobile phone card is down by Unicom, or it may be because your phone bill is overdrawn or your account number is abnormal. At this time, you need to contact Unicom customer service in time to solve it.

If the above methods still can't solve the problem, I suggest you contact Unicom customer service for help in time.
