When your mobile data works on WhatsApp, Chrome, or YouTube but not on certain apps, it means your phone isn’t truly offline — instead, those affected apps are being blocked by settings, restrictions, or background rules.
This problem is very common in 2025 due to new Android security features, carrier data rules, and app permissions.
Here are the real causes and proven fixes.
✅ 1. App Has Data Restriction Turned On
Android allows you to restrict mobile data app-by-app.
If a specific app can’t load anything, it might be restricted.
Fix:
Go to:
Settings → Apps → Choose the app → Mobile data & Wi-Fi → Enable “Allow data usage”
Also enable:
-
Background data
-
Unrestricted data (if Data Saver is on)
If background restrictions affect other apps, refer to:
👉 How to Stop Background Apps From Secretly Using Data & Battery
✅ 2. Data Saver Mode Is Blocking Some Apps
Data Saver blocks apps from using mobile data in the background — and sometimes even in the foreground.
Fix:
Settings → Network & Internet → Data Saver → OFF
If you want it ON, then allow:
Unrestricted Data Access → Select the affected apps

✅ 3. VPN or Proxy Is Blocking the App
Many VPNs block streaming, banking, gaming, or government apps.
Fix:
-
Turn off VPN
-
Remove Proxy from Wi-Fi/Mobile settings
-
Restart app

✅ 4. Incorrect APN Settings
If your network APN is misconfigured, some apps won’t load — especially video streaming, social media, and cloud services.
Fix:
Go to:
Settings → Mobile Network → Access Point Names (APN)
Then:
-
Select your SIM provider’s official APN
-
Reset to default

✅ 5. App Cache or Network Cache Is Corrupted
Corrupted cache can block the app from connecting online.
Fix:
Settings → Apps → Select the app → Storage → Clear Cache
If still failing:
-
“Clear Data” (This logs you out but fixes deeper errors)

✅ 6. App Server Is Down or Region-Blocked
Some apps temporarily go offline or block regions.
Fix:
-
Test the app using WiFi
-
Check with another phone
-
Search the app’s status online
If it works on WiFi but not mobile data, then your carrier is blocking content (often streaming/gaming apps).
✅ 7. Internet Type (4G/5G) Is Incompatible with the App
Certain older apps don’t load correctly on unstable 5G networks.
Fix:
Switch between:
5G → 4G → 3G
Then test the app again.
