9 Ways to Fix Facebook Not Working on Mobile Data

Quick Tips

• Firstly, check the status of Facebook’s server. It may be down, and thus, your Facebook app isn’t working.
• Next, disable Facebook’s built-in data saver mode to ensure the app has unrestricted internet access.
• If Facebook is still not working on mobile data, try resetting the APN settings to refresh cellular data connectivity and resolve bugs.

Basic Troubleshooting

• Check Facebook’s status: Maybe Facebook servers are down, visit Downdetector and search for Facebook. If the issue exists, wait for Facebook to fix it.
• Check your mobile data status: Have you exhausted your mobile data? Or does Facebook not have network access permission? Check these details before you move on.
• Change network type: Is your internet connection stable? Try switching the network (disable 5G) to see if the condition improves.
• Disable system-wide data saver mode: Both Android and iOS boast a dedicated data saver mode to apply some breaks on cellular data consumption. If you browse Facebook when the data saver mode is on, it may fail to load the content. Disable it for unrestricted use.
• Update or reinstall Facebook: Facebook regularly releases updates to add new features and fix bugs, such as the app not working on mobile data. You should install the latest Facebook update and try again.

Fix 1. Disable Data Saver Mode on Facebook

While an active Data Saver mode in Facebook uses up to 40% less data, it may interfere with app function on cellular data. You can follow the steps below to disable it.

Step 1: Open the Facebook app on your phone > select the hamburger menu at the top right (Android) or bottom right (iPhone).

Step 2: Tap the gear icon to open Settings.

Step 3: Here, scroll down and select Media. Disable the Data saver mode from the following menu.

Fix 2. Enable Data Roaming

It could be as silly a reason as this. If you’re traveling or using an outstation SIM, the data roaming setting can be the culprit. Let’s ensure that data roaming is enabled.

On iPhone

Step 1: Go to Settings → Cellular or Mobile Data.

Step 2: Next, select Cellular Data Options (or Mobile Data Options). Here, toggle on Data Roaming.

On Android

Step 1: Open Settings → tap Mobile Networks → select the SIM.

Step 2: Toggle on Data Roaming.

Fix 3. Reset APN Settings

Whenever you face a cellular data-related issue, such as 5G not working, resetting the APN is a viable solution. The Access Point Name (APN) defines the network path for cellular data connectivity.

Resetting it will reset the bug that might be behind Facebook not working on mobile data. So, let’s do so.

On iPhone

Step 1: Go to Settings → Cellular/Mobile Data. Here, select Cellular/Mobile Data Network.

Step 2: Tap Reset Settings > Reset again to confirm.

On Android Devices

Step 1: Launch Settings > go to Connections.

Step 2: Tap Mobile Networks > select Access Point Names > tap the Menu button (three-dot icon).

Step 3: Select Reset to default > tap Reset again to confirm the action.

If nothing else works, try resetting the network settings to see if Facebook works on mobile data. Additionally, you can contact Facebook support and raise a complaint to resolve the issue.
