Why i call someone and it reaches voicemail. But they say i did not ring. What causes that and how to fix it

There could be a few reasons why this happens:

1. Network connectivity issues: Sometimes, network problems can cause delays in receiving call notifications. This could be due to a weak signal or other technical issues with the network.

2. Do Not Disturb mode: The person you're calling may have their phone set to Do Not Disturb mode, which would send your call straight to voicemail without ringing.

3. Call forwarding: The person you're trying to reach may have set up call forwarding to another number, so your call is being redirected before it reaches their phone.

To fix this issue, you can try the following steps:

1. Check your network connection and make sure you have a strong signal when making the call.

2. Ask the person you're calling to check if their phone is in Do Not Disturb mode or if they have any call forwarding settings enabled.

3. If the issue persists, you can try reaching out to your phone carrier for support or troubleshooting tips.

Overall, communication issues like this can be frustrating, but it's important to stay patient and try to troubleshoot the problem to find a solution.
