What to do
- Open the Voicemail tab and delete old messages to make sure the mailbox isn't full.
- Check that you have cellular signal and data, since visual voicemail loads over the network.
- Restart the iPhone to refresh its connection to the carrier's voicemail server.
- Go to Settings > Phone > Change Voicemail Password and reset it if you're being asked to re-enter one.
- Try turning Airplane Mode on and off to reset the cellular connection.
- If visual voicemail won't load at all, dial your own number or the carrier's voicemail access number directly to check messages the old-fashioned way.
- Check your carrier's app or website for any account alerts about your voicemail plan.
- If it still fails, contact your carrier, since voicemail setup is often controlled on their end.
When to call a pro
If voicemail still won't load or set up after these steps, your carrier needs to reset it from their end.
