Seeing a call fail on your Redmi Note 14 Pro can be annoying, especially when you're trying to reach someone. This usually happens when your phone struggles to connect properly to your carrier's network. A weak signal, a minor software hiccup in HyperOS, or a simple setting can often be the culprit.
Here are ten effective ways to fix those failed calls, starting with the quickest solutions you can try right now.
Toggle Airplane Mode On and Off
The fastest way to reset your cellular connection is by using Airplane Mode. This clears temporary network glitches that can block calls from going through. It's the first thing I'd try.
Just swipe down from the top of your screen to open the Quick Settings panel. Tap the airplane icon to turn Airplane Mode on, wait about 10 seconds, and then tap it again to turn it off. Your phone will reconnect to the network, which often solves the problem immediately.
Check Your Signal Strength
Weak cellular signal is the most common reason for call failures. Look at the signal bars in the top-right corner of your screen. If you only have one or two bars, try moving to a different location.
Going near a window or stepping outside can make a big difference. The Dimensity 7300 Ultra chip is capable, but it still needs a decent signal from the tower to maintain a stable call connection.
Force Restart Your Phone
A simple restart can clear out many software-related issues that might be interfering with the phone app or network services. If your phone is acting sluggish, this is a good step.
Press and hold the Power button for about 15 seconds. Keep holding it until you see the Redmi or Xiaomi logo appear on the screen, which means the phone is restarting. This is different from just turning the screen off and on.
Check Do Not Disturb and Focus Modes
HyperOS has various modes that can silence or block calls. Make sure you haven't accidentally enabled a setting that's preventing connections.
Swipe down to see your Quick Settings and check if an icon like a crescent moon or a specific Focus mode is active. You can also go into Settings > Sound & vibration > Do Not Disturb to see the schedule and rules.
Verify Your SIM Card
A loose, dirty, or faulty SIM card is a classic cause of call problems. It's worth taking a minute to check it. You'll need the SIM ejector tool that came with your phone.
Gently push the tool into the small hole on the SIM tray to pop it out. Remove the SIM card, give the gold contacts a quick wipe with a dry, soft cloth, and then reinsert it firmly. Make sure the tray is fully seated back into the phone.
Update Your Carrier Settings and Software
Carrier updates are small files that improve how your phone connects to your specific network. Software updates for HyperOS fix broader bugs. Both can resolve calling issues.
For carrier updates, connect to Wi-Fi and go to Settings > About phone > Carrier settings. If an update is there, install it. For a full system update, go to Settings > About phone > MIUI version and tap "Check for updates."
Reset Your Network Settings
This is a more thorough step that clears all your saved Wi-Fi networks, Bluetooth pairings, and cellular preferences. It won't delete your personal data like photos or messages, but you will have to reconnect to Wi-Fi networks afterward.
To do this, go to Settings > Connection & sharing > Reset Wi-Fi, mobile networks and Bluetooth. Tap the reset option and confirm. Your phone will reboot and you can test your calls again.
Check for Blocked Numbers
It's easy to accidentally block a number. If calls are failing to one specific person, it's worth checking your block list. Open your Phone app and tap the three-dot menu in the top corner.
Go to Settings > Blocked numbers and see if the number is listed there. If it is, you can tap to remove it from the list. Also, check any call screening or harassment filter settings that might be too aggressive.
Switch Between 4G and 5G
Sometimes, the higher-speed 5G network in your area might have weaker call reliability than 4G LTE. You can try forcing your phone to use 4G to see if it stabilizes your calls.
Go to Settings > SIM cards & mobile networks. Select your SIM card and tap on Preferred network type. Choose "4G/3G/2G (auto)" instead of "5G/4G/3G/2G (auto)". Test your calls, and you can always switch it back later.
Disable Battery Saver for Calls
The aggressive battery optimization in HyperOS can sometimes interfere with background processes, which might include the phone's connection service. If you frequently use Battery Saver, try turning it off when you need to make important calls.
Swipe down and tap the battery icon, or go to Settings > Battery and disable Battery Saver. You can also go to Settings > Apps > Manage apps, find your Phone app, tap on "Battery saver", and set it to "No restrictions".
