What is phone rings twice then goes to voicemail?

When a phone rings twice and then goes to voicemail, it usually means that the person you are calling is either busy or unable to answer the call. In some cases, this may also happen if the person has set their phone to divert all calls directly to voicemail.

This can happen for several reasons, such as the phone being switched off, the battery being dead, or the phone being out of range of the network. It is also possible that the person is on another call or has set their phone to silent or vibrate mode.

If you are frequently experiencing this issue, it may be a good idea to check with your mobile provider or the recipient of the call to see if there are any issues with their phone or network. In some cases, you may need to adjust your own phone settings or contact your provider for assistance.
