Dear, the call failure reasons are as follows:1Network Connectivity Issues:

Call failures can be caused by network failures, poor internet connection, or the inability to connect to the other device. You can try restarting your router or adjusting your network environment to improve your network connection. 2.

Insufficient account balance or limitations: Some service providers have specific limits based on their billing policies, such as insufficient balances or infrequent use that may cause calls to fail. You can check the balance in your account or call a different number to troubleshoot these issues.

4.The number grid is only included in the question: Please check whether the number to be dialed is in the correct format, which involves the country and region** and other normative issues.

5.Device compatibility issues: For some applications, the compatibility of the device can also cause the call to fail.

There are a number of possible reasons why a call can fail, but here are some of the common ones:1 Unstable or no signal: If you are in an area with poor network coverage or an unstable network signal, it can cause the call to fail.

2 Incorrect number entry: If you enter the wrong number, it will also cause the call to fail. It is recommended that you double-check the correctness of the ** number.

3 The other party's mobile phone is turned off or not in the service area: If you are dialing the other party's mobile phone, and the other party's mobile phone is turned off or not in the service area due to insufficient battery or other reasons, the call will also fail. 4 Communication equipment failure:

It can also be due to a malfunction of the communication device you are using, such as a crash in the mobile phone software. 5 Carrier issues: If you're using a service provided by your carrier, your call may fail due to carrier issues.

We recommend that you troubleshoot and handle the problem based on your specific situation, and try again when the network is stable, the number is correct, and the other party's mobile phone is turned on and can be answered normally. If the call still fails, we recommend that you contact the relevant customer service agent for a resolution.
