Are you tired of your iPhone dropping calls at the most inconvenient moments? Well, you’re not alone. Many iPhone users experience this frustrating issue, but fear not!

Call Failed in iPhone: Step-by-Step Tutorial

Before we dive into the steps, let’s understand what we’re trying to achieve. We want to fix the call failed issue on your iPhone so that you can make and receive calls without any interruptions. Let’s get started!

Step 1: Check Your Signal Strength

Make sure you have a strong signal. If you’re in an area with poor reception, try moving to a location with better service.

When your iPhone says "call failed," it could be due to weak cellular reception. Check the signal bars at the top of your screen. If you see only one bar or no bars, that’s likely the culprit. Try going outside or moving closer to a window to improve your signal strength.

Step 2: Restart Your iPhone

Restart your iPhone to refresh its connection to the network.

Sometimes, a simple restart can solve a multitude of problems. Press and hold the power button until the "slide to power off" option appears, then slide it. After your iPhone turns off, press and hold the power button again until you see the Apple logo.

Step 3: Update Carrier Settings

Check for any available updates for your carrier settings and install them.

Carrier settings updates can include updates from your carrier for improving connectivity and performance. To check for updates, go to Settings > General > About. If an update is available, a prompt will appear, allowing you to update.

Step 4: Remove and Reinsert Your SIM Card

Carefully remove your SIM card and then reinsert it to ensure it’s properly seated.

Sometimes, the SIM card may not be seated correctly or could have collected some dust. Use a SIM card ejector tool or a paperclip to pop open the SIM card tray, remove the SIM card, clean it gently with a soft cloth, and place it back into the tray.

Step 5: Reset Network Settings

Reset your network settings to clear any network-related issues.

This step will erase all current saved settings, including Wi-Fi passwords, preferred networks, and VPN settings. To reset network settings, go to Settings > General > Reset > Reset Network Settings. Enter your passcode if prompted, and confirm the reset.

After completing these steps, your iPhone should hopefully be free from the "call failed" issue, and you can go back to enjoying uninterrupted calls.
