I don't know what the situation is, the traffic can be used, and I can't make a phone call or send a message.

First, the common reasons why mobile phones can't answer the phone and their solutions are as follows:

1. Check whether the mobile phone is in arrears, and suggest to pay for recharging;

2. Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

3. Check whether the function or signal of the mobile phone is normal. It is recommended to change your mobile phone or location and try again.

4. Try restarting or changing your mobile phone to see if you can answer the phone;

5. Bring the mobile phone card to the local business hall for testing or replacement.

Second, you can't receive SMS or verification code for the following reasons:

1. You can check whether the mailbox is full first. If it is full, please delete some information.

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

3. After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.
