Seeing a call fail on your POCO X7 Pro is a real nuisance, especially when you're trying to reach someone quickly. This usually means your phone is having trouble connecting to your mobile network properly. A weak signal, a minor software hiccup in HyperOS 2, or a simple setting can often be the culprit.
Let's run through the most effective fixes, starting with the quickest ones you can try right now.
Toggle Airplane Mode On and Off
This is the fastest way to refresh your mobile connection. Swipe down from the top of your screen to open the Quick Settings panel. Tap the Airplane Mode icon to turn it on, wait about 10 seconds, and then tap it again to turn it off. This forces your phone to reconnect to the cellular network from scratch.
Check Your Signal Strength
Look at the signal bars in the top-right corner of your screen. If you only have one or two bars, you're likely in a weak coverage area. Try moving to a different room, near a window, or even stepping outside. The large 6000mAh battery in the X7 Pro gives you great endurance, but it won't help if there's no signal to connect to.
Force Restart Your POCO X7 Pro
A simple reboot can clear out temporary glitches that might be affecting the phone app or network services. Just press and hold the Power button on the side for about 15 seconds. Keep holding it until you see the POCO logo appear, which means the phone is restarting. This is different from a normal restart and often fixes stubborn software issues.
Check for Focus Mode or Do Not Disturb
HyperOS 2 has various Focus modes that can sometimes interfere with calls. Swipe down from the top to check your Quick Settings. If you see an icon like a crescent moon or a specific Focus mode is active, tap it to turn it off. Also, open the Settings app, go to Sound & vibration > Do Not Disturb, and make sure it's disabled.
Verify Your SIM Card
A loose or dirty SIM card is a common cause of call failures. Grab the SIM ejector tool that came with your phone (a small paperclip works too) and pop out the SIM tray. Carefully remove the SIM card, give the gold contacts a gentle wipe with a soft, dry cloth, and reinsert it firmly. Make sure the tray clicks back into place securely.
Update Your Carrier Settings
Sometimes your mobile carrier pushes small updates to improve network connectivity. Make sure your phone is connected to Wi-Fi, then go to Settings > About phone > SIM status. While you're there, your phone might automatically check for updates. You can also try going to the system updater, as carrier updates are sometimes bundled with security patches.
Switch Between 5G, 4G, and 3G
If you're in an area with spotty 5G coverage, your phone might struggle to maintain a stable voice call while searching for the faster signal. You can force it to use a more reliable network. Go to Settings > Mobile network. Tap on your SIM card, then tap Preferred network type. Try selecting "4G/3G/2G" instead of "5G" and see if your calls connect more reliably.
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 there. If it is, you can tap the remove icon next to it to unblock.
Reset Your Network Settings
This will clear all your saved Wi-Fi networks, Bluetooth pairings, and mobile network configurations back to default. It won't delete your personal data like photos or messages. Go to Settings > Additional settings > Backup & reset. Tap on Reset phone, then select Reset network settings. Confirm your PIN or pattern if prompted, and your phone will restart.
After the reset, you'll need to reconnect to your Wi-Fi and re-pair any Bluetooth devices, but it often resolves deep-seated network issues.
Update HyperOS and Your Apps
Software updates frequently include bug fixes for connectivity and calling problems. First, connect to a stable Wi-Fi network. Go to Settings > About phone > HyperOS version and tap "Check for updates." Install any available system update.
Also, open the Google Play Store, tap your profile icon, and go to
Manage apps & device > Updates available. Update your Phone app and any carrier services apps you see listed.Contact Your Mobile Carrier
If you've tried everything and calls are still failing, the problem might be on your carrier's end. Give their customer service a call from another phone. Ask if there are any known network outages or maintenance happening in your area. You can also ask them to reprovision your SIM card on their network or check if there are any account-specific issues preventing calls.
