Seeing "Call Ended" or calls dropping unexpectedly on your Redmi Note 13 Pro is a common headache, especially when you're trying to get something important done. This usually happens when your phone struggles to maintain a stable connection with your carrier's network. Weak signals, a minor software hiccup in MIUI, or a single incorrect setting are often the culprits.
Here are 10 practical fixes to get your calls working again, starting with the quickest one you can try right now.
Toggle Airplane Mode On and Off
The fastest way to refresh your cellular connection is with Airplane Mode. This forces your phone to disconnect from and then reconnect to the network, clearing out any temporary glitches. Swipe down from the top of your screen to open the Control Center and tap the airplane icon.
Wait about 10 seconds for it to fully disconnect, then tap the icon again to turn it off. Your phone will search for the network again. Give it a moment, then try making a call.
Check Your Signal Strength
Weak signal is the number one 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 room or near a window.
Buildings with thick walls or remote areas can really interfere. If you see an "X" or "No Service," you're likely in a dead zone and will need to move to get a call out.
Restart Your Redmi Note 13 Pro
A simple reboot can clear out temporary software bugs that might be affecting the phone app or network services. Just press and hold the power button until the power menu appears, then tap "Restart."
If the screen is unresponsive, you can force a restart by holding the power button down for 15 seconds or more until you feel the phone vibrate and see the Redmi logo.
Verify Do Not Disturb and Focus Modes
MIUI's Focus Modes or Do Not Disturb can sometimes be configured to block all calls, even from your contacts. Swipe down from the top and check if an icon like a crescent moon or a specific focus (like Work or Sleep) is active in your status bar.
Tap it to turn it off. For a deeper check, go to Settings > Sound & vibration > Do Not Disturb to see the rules and make sure calls are allowed.
Check for Blocked Numbers
It's easy to accidentally block a number. Open your Phone app and tap the three-dot menu in the top-right corner. Go to Settings > Blocked numbers.
Scroll through the list to see if the number you're trying to call (or receive calls from) is listed here. If it is, tap the remove icon next to it to unblock.
Ensure Mobile Data and Roaming Are Correct
While calls use the voice network, some settings can still interfere. Go to Settings > SIM cards & mobile networks. Select your primary SIM card and make sure "Mobile data" is enabled.
If you're traveling, you might need to enable data roaming from this same menu. Be aware roaming charges may apply, so check with your carrier first.
Try Switching Network Type
Sometimes, forcing your phone to use an older, more stable network type like 3G can fix call issues, especially in areas with spotty 4G/5G coverage. Go to Settings > SIM cards & mobile networks and tap your SIM.
Tap Preferred network type and select "3G" instead of "5G/4G/3G/2G auto." Test a call. Remember to switch it back to the auto mode later for the best data speeds.
Check and Reinsert Your SIM Card
A loose, dirty, or faulty SIM card is a classic cause of call problems. Power off your phone first. Then, use the SIM eject tool (found in the box) to pop open the tray on the bottom edge.
Carefully remove the SIM, blow gently on the tray to remove any dust, and re-seat the card. Push the tray back in firmly until it clicks. Power your phone back on and see if it registers the network properly.
Update Your Software and Carrier Settings
Xiaomi regularly releases MIUI updates that fix bugs, including network-related ones. Connect to Wi-Fi, then go to Settings > About phone > MIUI version. Tap "Check for updates" and install any available update.
Carrier settings updates happen automatically most of the time, but you can check by going to Settings > About phone > All specs and tapping "MIUI version" repeatedly (about 7 times) to enable Developer Options, though a simple reboot often triggers a check.
Reset Your Network Settings
If calls are still failing, resetting network settings can be a powerful fix. This will erase all Wi-Fi passwords, paired Bluetooth devices, and cellular network preferences, but it won't touch your personal data like photos or messages.
Go to Settings > Additional settings > Backup & reset > Reset phone. Tap Reset network settings. You'll need to enter your screen lock PIN or password to confirm. After the reset, you'll have to reconnect to Wi-Fi and re-pair Bluetooth devices.
