What to Do If an App Can’t Access Mobile Data on Your OPPO Phone

If you notice that only one application on your OPPO smartphone cannot connect to mobile data while other apps work normally, it may be due to permission settings, data restrictions, or a problem with the app itself. This guide walks you through step-by-step troubleshooting methods to help resolve the issue.

Step 1: Check the App’s Network Access Permissions

Sometimes, mobile data access may be disabled for a specific app. To check and adjust this:

1. Go to [Settings] > [Mobile Network] > [Data Usage] > [Network Access].

2. Find the app that’s not working.

3. Tap the app and ensure both Mobile Data and Wi-Fi access are enabled.

Step 2: Check If Data Saving Is Enabled

When data saving is turned on, background apps may be restricted from using mobile data to reduce traffic consumption. This can block the app’s internet access even if it’s permitted.

To disable data saving:

1. Go to [Settings] > [Mobile Network] > [Data Usage].

2. Look for [Data Saving] and turn it off.

Step 3: Test the App on Another Device

Install the same app on a different phone using the same mobile data network. If the app still cannot connect, the issue may lie with the app itself, not your phone. In this case, it’s best to contact the app developer or the software provider’s customer support for assistance.

Step 4: Uninstall and Reinstall the App

If the app still fails to connect, try reinstalling it:

1. Uninstall the app.

2. Restart your device.

3. Reinstall the app from the official app store.

   Note: Uninstalling may delete app data. Backup your data if needed before proceeding.

If you’re using any third-party security apps, network boosters, or accelerators, disable or uninstall them, as they may interfere with app connectivity.

When to Contact OPPO Support

If none of the above solutions resolve the issue:

• Contact the OPPO Support team for further assistance.

• Or, back up your phone data and bring your device along with proof of purchase to an OPPO Authorized Service Center. A professional technician can inspect and fix the issue.
