Little genius telecom card can't make calls

There may be several reasons why the little genius telecom card can't make a call:

1. The watch card is in arrears: if the watch card is in arrears, it needs to be recharged to avoid affecting its use.

2. The watch card is not installed correctly: If the watch card is not installed correctly, it needs to be reinstalled to ensure normal communication.

3. The watch card does not have the function of voice call and incoming call display: If the watch card does not have the function of voice call and incoming call display, it needs to be opened at the operator to ensure that you can answer the phone and send short messages normally.

4. Watch screen failure: Watch screen failure requires after-sales maintenance to ensure normal display and operation.

5. The device is not compatible with the calling card: If the device is not compatible with the calling card, it may lead to the inability to make calls. Users need to buy compatible devices and calling cards to solve this problem.

If the above methods can't solve the problem, it is recommended to contact Xiaotiancai's official customer service for consultation or maintenance in order to get more professional help.
