2. Call failed on iPhone? Disable Do Not Disturb.

When we’re busy with work or personal business it’s good not to be disturbed by the vibrations and ringings of our phones. The ‘Do Not Disturb’ is a nifty feature that’s meant to silence calls, vibrations, and most notifications, but it isn’t supposed to block calls. Nonetheless unconnected things like this often mysteriously fix these issues.

Here’s how to turn off your ‘Do Not Disturb’ status:

1. Start the Settings app on your iPhone
2. Locate the Do Not Disturb and toggle it off if it’s not yet already

After turning off this feature, calls and notifications will no longer be filtered by your iPhone.

3. Call failed on iPhone? Dial *#31# or Check your Caller ID.

Chances are your number could be hidden, thereby causing your calls to fail.

iPhone lets you call other numbers without revealing your caller ID or phone number. This sneaky trick can sometimes compromise your calls and cause them to fail.

To unhide your phone number and show your caller ID, Apple introduced a hidden code on your iPhone that disables your anonymity status on outgoing and incoming calls.

Follow these steps to unhide your phone number:

1. Start by launching the Phone app.
2. Now, touch on the Keypad tab located near the bottom of the display and type in *#31#.
3. Finally, hit call and that should unhide your phone number.

Alternatively, you can also:

1. Head over to Settings.
2. Next, scroll down and tap Phone.
3. Finally, Show My Caller ID should be on your screen, set the button to On position.

Both solutions will make your phone number accessible to people you contact.

4. Call failed on iPhone? Change the Date and Time Settings.

Some users manually set their clocks 15 minutes ahead of time to help them be punctual.

Whether you’re that kind of person or not, ‘Date and Time’ settings can often malfunction or glitch for no reasons. This is a weird solution, but more often than not unusual solutions like this can fix your issue.

Follow these steps to change your Date and Time Settings:

1. Launch the Settings app from your home screen.
2. Next, tap on General.
3. Next on, tap Date & Time.
4. Turn on ‘Set Automatically‘ and configure your Time Zone to your geographical location.
5. Now if your settings are already set to automatic, try to disable and enable ‘Set Automatically’ to refresh your settings.

Whether it works or not, reverting to your normal 15-minute advance time settings should not cause this issue.

5. Call failed on iPhone? Restart Your iPhone.

There are a number of easier fixes you can try on this guide that involve configuring your settings, but if you’re impatient and want to take a quick break; restarting your iPhone will often resolve most minor errors while you’re free to do a quick 5-minute task.

Follow these steps to restart your iPhone:

1. First, hold the power button on your iPhone until you see a red power slider
2. Now, swipe the power off slider to the right and wait for your device to turn off completely.
3. Turn your iPhone back on by holding down the power button.

6. Call failed on iPhone? Check for Blocked Numbers.

Blocked numbers will be unable to contact you through texts or calls. In the same token, you will also be unable to reach them.

Follow these steps to check if you’ve blocked the number you’re trying to contact:

1. Launch the Settings app on your iPhone.
2. Next, scroll down and tap Phone.
3. Finally, tap on Block Contacts and make sure the number you’re trying to contact isn’t in the list.
4. If the person or number you’re trying to contact is among blocked contacts, just tap on the number and unblock it. Doing so mayresolve your issue.

7. Check If Call Forwarding is Turned On.

‘Call Forwarding’ sets up incoming calls to be redirected to another phone number. With call forwarding enabled, any incoming calls will immediately ring on another phone without notifying you.

Follow these steps to check if Call Forwarding is turned on:

1. start the Settings app on your iPhone.
2. Now, scroll down and tap Phone.
3. finally, Tap on Call Forwarding and toggle the switch next to it to turn it off.

After doing so, all the incoming calls should start notifying your phone instead of being redirected. If you are still experiencing problems, try the next solution.

8. Disable Dial Assist.

Most cellular calls are made in the same region, while international calls are commonly connected through Wi-Fi. Every country has a different prefix (the first two numbers of your phone number, like +1 for the US). Because of this, whenever you dial a phone number there is an automatically assigned local prefix. This is what ‘Dial Assist’ does.

The automated feature can be an issue when you’re trying to contact someone with a foreign number or a different prefix. By disabling ‘Dial Assist’, it gives you the guarantee that the number you dial is the one that’s going to receive your call.

Follow these steps to disable Dial Assist on your iPhone:

1. Launch the Settings app on your iPhone.
2. Scroll down and tap Phone.
3. Now toggle off the switch next to Dial Assist.
4. Finally, restart your iPhone

After restarting your device, dial-in or choose through your contacts the full number of the person you wish to contact. Your iPhone should now dial the numbers of your contact without any automated interventions.

Maybe your carrier settings are out of date, which may cause an error in your calls.

Just like iOS updates, it’s a good idea to keep your carrier settings up to date. Updating your carrier settings is quick and easy however, speeds vary depending on your Wi-Fi network.

4. Finally, if an update is available, you should see a notification.

However, if the problem persist, you can check the next solutions to try and fix your call failed problems.

10. Check Your Wi-Fi Calling Options.

‘Wi-Fi Calling’ gives you the ability to receive and make calls over a Wi-Fi connection instead of your phone’s cellular network.

This can come in handy when you want to make a call and are connected to a Wi-Fi network. However, this can get in the way of making regular cellular calls.

Disabling or enabling this setting has worked for most users. Follow these steps to enable/disable ‘Wi-Fi Calling’:

1. launch the Settings app on your iPhone
2. Now, scroll down and tap Phone.
3. Next, press Wi-Fi Calling and disable/enable it. (whichever is the opposite of the current setting).
4. Finally, restart your iPhone.

Now your calls should be made entirely through your cellular network or with the help of your Wi-Fi connection.

11. Reset Your Network Settings back to Default.

If there’s nothing wrong with your preferences, then there could be an issue with the networks you’re trying to connect to. Resetting your network settings to factory default may fix your issue.

Resetting network settings does not remove any of your personal data except your VPN, Wi-Fi passwords, and cellular settings which are networks your phone gets services from.

Follow these steps to reset your network settings:

1. start the settings app on your iPhone
2. Now, tap General.
3. Next, tap on Reset.

12. Eject and Reinsert the SIM Card.

A method of its time, the troubleshooting step of removing and reinserting your SIM card has worked for most users. In terms of hardware-related issues that could be responsible for your calls failing; adjustments, scratches, damage, or dust on your SIM card could interfere with your cellular experience.

If you’ve never done this before don’t be alarmed, it’s not that difficult and can be done in a few simple steps.

Follow these steps to remove and reinsert your SIM Card:

1. On the side of your iPhone, you’ll see a SIM tray. If your device is on a case, then you will want to take it off in order to locate the SIM tray.
2. Once you locate the tray, use a paper clip or SIM-eject tool to press into the hole. This should eject the SIM tray up a couple of millimetres.
3. Next, remove the SIM tray with your SIM card inside it.
4. Then, inspect the SIM card for damages and dust.
5. If you can’t find any scratches you can gently wipe the SIM on a clean and smooth cloth before inserting it back in with the SIM Tray.

If all the methods so far haven’t resolved your issue, perhaps the last two major fixes will fix your problem.

13. Update iOS.

Any iOS device can start to get bugs and problems if its software is out of date.

Often enough updating your iOS fixes most problems, including failed calls. Because bugs, glitches, and other performances require monthly updates and changes in code; regularly updating your iPhone’s iOS is a great way to avoid most errors and bugs.
