How to Set a Mobile Data Usage Limit on Xiaomi / Redmi Phones

Running out of your monthly data plan? Set a hard data limit on your Xiaomi phone — HyperOS will warn you when you're close and cut mobile data when you hit the cap.

How to Set a Data Usage Limit

1. Go to Settings
2. Tap SIM Cards & Mobile Networks (or Traffic Management)
3. Select Data Usage
4. Tap "Set Data Limit" or "Monthly Data Limit"
5. Enter your monthly data allowance (e.g., 10 GB)
6. Set the billing cycle reset date (when your plan resets each month)
7. Enable "Alert me when I reach" → set a warning at 80% usage

Enable Data Limit Kill Switch

Toggle "Disable mobile data at limit" to ON. When you hit 100% of your set limit, HyperOS automatically turns off mobile data. You'll receive a notification.

Set a Data Warning Separately

You can also set a warning threshold below the hard limit:

• Warning at 8 GB → notification to slow down usage
• Limit at 10 GB → mobile data cut off

Monitor Usage by App

Settings > SIM Cards & Mobile Networks > Data Usage > App Data Usage shows which apps consumed the most data this billing cycle. Common heavy hitters:

• YouTube / Netflix (video streaming)
• Cloud backup (Google Photos, Mi Cloud)
• App updates over mobile data

Pro Tips for Saving Data

• Enable Data Saver (Settings → Network → Data Saver) to restrict background data globally
• Set YouTube to "Wi-Fi only" in app settings
• Disable "Auto-update apps over mobile data" in Play Store settings
