The ‘Call Failed’ error that you are facing on your iPhone shows up whenever the iPhone fails to place a call successfully. If you start to explore the probable solutions, there are many factors that may lead to this calling issue on your iPhone. This guide has explored all those solutions that you may need to fix this problem on your own.
Fix 1 – Disable the Calling Line ID Restriction
If you have your cellular lines restricted on your iPhone, all of your calls may get failed in the due process. Whatever is the reason for this, revoking the restriction won’t take much time.
Step 1 – So, open up the Phone app.
Step 2 – Next, open up the dialer in there and then, dial up this number.
*#31#
Wait for a few seconds, and you will see that the restrictions on the cellular line is revoked. Finally, it should show you this message –
Setting Interrogation Succeeded. Calling Line ID Restriction Disabled.
Step 3 – Tap the “Dismiss” button there to close that prompt.
Check whether you can dial up your number. Test if this works.
Fix 2 – Refresh the network system
You can refresh your iPhone’s network system simply by putting the device in Airplane mode and revoking it later.
Step 1 – Open up the Control Center.
Step 2 – In the Control Center page, you can just enable the Airplane mode from there.
Step 3 – Leave the iPhone for a few seconds in that state.
Step 4 – Later, tap the same Airplane mode button to revoke the flight mode.
Once it is revoked and all the cellular connection is restored, you can try to dial up any number of your preference. Check if the call facility is actually working or not.
Fix 3 – Let iPhone choose the network
Sometimes when you have selected the mobile network manually, the cellular service may get restricted if you have relocated.
Step 1 – In the iPhone Settings, open up the “Mobile Service” or “Cellular data” section.
Step 2 – Later, load up the “Network Selection” option there.
Step 3 – Select the “Automatic” channel.
When your network type is selected as ‘automatic’ mode, iPhone can manage the carrier network automatically. This should fix the call failed error on your device.

Resetting the network settings can fix any irregularities in the carrier settings as well.

Step 2 – Next, touch the “Transfer or reset iPhone” option.
Step 3 – Later, tap the “Reset” option there.
Step 4 – Touch the “Reset Network Settings” option from the following step.
Once the network settings are reset, try calling others to test whether this works or not.
Fix 5 – Eject the SIM card
Manually ejecting the SIM card and re-inserting it can reset the carrier network settings. It can fix any alignment issues as well.
Step 1 – Get the iPhone out of the casing.
Step 2 – Use the SIM ejector tool to eject the SIM card tray.
Step 3 – Give it a few seconds.
Step 4 – Later, re-insert the same SIM tray to your iPhone.
Wait for a few seconds and wait for the iPhone to restore the cellular connections. You can call everyone without any issues.
