6 Reasons Why iPhone Rings Once Then Goes to Voicemail 

Being unable to answer a call might be frustrating, especially when your phone only rings once! But why does this keep happening? Could it be that something is wrong with your phone? 

Don’t worry; you don’t have to get your phone inspected and repaired by a technician to resolve this problem. Here are a few potential reasons, along with their fixes:

  1. Outdated iOS Version

The one-ring issue can also be a software bug due to an outdated iOS version. Luckily, this can be easily fixed by simply updating your iPhone to the latest version of iOS. 

To update your iPhone, carry out the following steps:

  1. Open the Settings app, then tap on General.
  2. Tab on Software Update, then follow the instructions on the screen.
  3. Once the update is complete, restart your iPhone, and this annoying issue should be resolved.
  4. The Do Not Disturb Feature Is Enabled

iPhones automatically silence all incoming calls and notifications when Do Not Disturb mode is activated so that you can get some peace and quiet. So, when a call comes in, your iPhone will ring once and then go straight to voicemail. 

Thankfully, this is easy to fix by simply turning off the Do Not Disturb feature, which can be done in several ways, including:

  1. Simply toggle the switch in the Control Center.
  2. You can also open the Settings app and tap on Do Not Disturb.
  3. Simply say, “Hey Siri, turn off Do Not Disturb,” and it will be turned off.
  4. An Unknown Caller Is Trying to Reach You

Yes, this issue often arises when someone unknown to you is trying to reach you repeatedly. If you receive many calls from an unknown number, your iPhone will end up ringing just once so that you don’t have to keep answering calls from an unknown caller.

To fix this problem, you should add the unknown number to your contacts manually or using Siri, or you can simply block the number if you don’t want to receive any calls from it. 

  1. You’re Using Spam Blocking Apps

Unfortunately, the spam blocking app that you’ve installed on your iPhone could be the reason why incoming calls go straight to voicemail.

Thankfully, there are a few solutions to this issue. You can:

  1. Add the number that is calling to your contact list.
  2. Turn off the spam blocking app temporarily.
  3. Uninstall the app by pressing and holding the spam blocking app icon until the quick action menu pops up. Next, tap Remove App, then Delete App, then Delete.
  4. There’s a Network Issue

If you find your iPhone ringing once and going to voicemail, your smartphone might have lost connection with the network.

If your iPhone is connected to a cellular network, then try moving to a different place. If that doesn’t work, try resetting the cellular network, then restarting your iPhone.

If you’re still having issues with this problem, contact your cellular provider and see if they’re having any issues with their network.

  1. Someone Has Blocked You

Your iPhone is ringing once and going to voicemail can be a sign someone might have blocked you. If this is the case, there’s nothing that you can do to unblock yourself.
