Mobile phone king card does not send text messages.

1. Check whether the number card has been opened. If it has not been turned on, it needs to be activated according to the activation manual before it can be used normally;

2. The number card can only be used within half an hour after opening. If you just apply, it hasn't been half an hour, I suggest you pay attention to it;

3. Confirm whether your mobile phone supports Unicom 4G, like some mobile custom machine can only support Unicom 2G network;

4. If it is a dual-card mobile phone, it is recommended to take out other cards, set Tencent Dawang Card as the main card, and put in other cards after opening the number card and privileges;

5. If you can't use more than one mobile phone, you need to go to Unicom's business hall to get a replacement card.
