Set the Action for When Your Data Plan Runs Out
If your mobile data suddenly stops working before the month is over, MIUI may already be cutting it off automatically once you hit your set limit. Some people only want a heads-up instead of losing their connection outright, but that only works if the right action is selected in the data usage settings. Without checking this setting, you can end up with dead mobile data at the worst possible moment.
Set Wi-Fi Hotspot Data Limit
If your mobile data plan drains fast whenever you share your Xiaomi phone's Wi-Fi hotspot with a laptop or tablet, an unlimited hotspot session is usually the cause. MIUI lets you cap the exact amount of data the hotspot can share and pick what happens once that cap is reached.
Set Up Unlock with Bluetooth Device
If your Xiaomi phone stays locked even though your paired Bluetooth accessory is nearby, the Unlock with Bluetooth device feature is probably still off. Once active, the phone unlocks automatically near that device and stays unlocked as long as the connection holds. This only works with Xiaomi's own Bluetooth accessories, not with third-party headphones or wearables.
Delete an APN Entry
A wrong or duplicate access point can block mobile data or MMS on your Xiaomi phone, even after you switch carriers or SIM cards. If an old APN profile stays behind, the device sometimes keeps trying to use it instead of the correct one. Removing the unused entry clears up the confusion without touching your other network settings.
Pair a Bluetooth Device
If your headset, earbuds, or speaker will not connect to your Xiaomi phone, the accessory usually needs to be paired first before Bluetooth can use it. Until pairing finishes, the phone will not list it as an active connection, so audio and calls stay on the built-in speaker.
Connect Manually to a Hidden Wi-Fi Network
If your Xiaomi phone does not list a wireless network under available connections, the router is likely broadcasting with a hidden SSID or sitting outside the usual scan range. In that case MIUI needs the exact network name and password entered by hand instead of picking the network from a list. Typing the SSID wrong or missing the correct security type is the most common reason the manual entry still fails.
Turn Mobile Data On or Off
When your Xiaomi phone shows no internet outside Wi-Fi, mobile data is usually switched off or was toggled off by accident after a network change. This also blocks messaging apps and background sync, since they rely on the cellular connection once Wi-Fi drops. A wrong or missing APN can cause the same symptom even when mobile data itself is enabled.
Set Default SIM for Mobile Data
If your Xiaomi phone keeps using the wrong SIM for mobile data, downloads and browsing can suddenly stop working on the plan you actually pay for. With two active SIM cards, MIUI needs one clear default data connection, otherwise apps may quietly try to load data through the wrong carrier. Picking a fixed data SIM stops that back and forth.
Connect to a Wi-Fi Network
If your Xiaomi phone shows no internet access or keeps prompting for a network password, the device usually just is not linked to any Wi-Fi yet. Mobile data alone will not give you access to a home or office network, and an inactive Wi-Fi radio hides every nearby network from the list. Once Wi-Fi is switched on, both private networks with a password and open public hotspots become selectable.
