Mobile phone cards don't need text messages, they can't even answer the phone, they can only surf the Internet. What happened?

1, check whether the number card is in arrears;

2. Restart the machine test;

3, change the machine and change the card test;

4. Whether the signal is normal;

5. If you can dial after changing your mobile phone, there may be something wrong with your mobile phone settings. It is recommended to contact the mobile phone after-sales service. If you still can't dial after changing your mobile phone, it may be a problem with the number card. You can go to the business hall to check the number card, or you can call 10 10 for manual customer service verification.
