PUBG Mobile Not Working on iPhone Cellular Data: Fixes

If PUBG Mobile works on Wi-Fi but stalls, disconnects, or will not log in over cellular data, first confirm that iOS allows the game to use mobile data. Then test the connection, restart the app and iPhone, update the game, and rule out VPN or carrier problems. The old workaround of logging in on Wi-Fi and switching networks may help temporarily, but it does not fix the underlying cause.

1. Allow PUBG Mobile to use cellular data

1. Open Settings > Cellular (or Mobile Service, depending on region).
2. Make sure Cellular Data is enabled.
3. Scroll to the app list, tap Show All if necessary, and turn on access for PUBG Mobile.
4. If the iPhone uses Dual SIM, confirm that the intended line is selected for cellular data.

Apple's cellular-data guide explains that an app whose switch is off can connect only through Wi-Fi.

2. Check whether cellular internet works outside the game

Turn Wi-Fi off and load a trusted website or another online app. If nothing connects, the problem is with the iPhone, SIM, data plan, signal, or carrier rather than PUBG Mobile. Toggle Airplane Mode on for about 10 seconds and turn it off, then try again in an area with a stronger signal.

Check that the data allowance has not been exhausted and that the carrier is not experiencing an outage. When roaming, mobile data may also remain unavailable unless Data Roaming is enabled; review charges with the carrier before changing that setting.

3. Close and reopen PUBG Mobile

Open the app switcher, swipe PUBG Mobile away, wait a few seconds, and launch it again. If the login screen offers a download or resource check, allow it to finish. Avoid switching repeatedly between Wi-Fi and cellular while files are being verified.

Restart the iPhone if reopening the app does not help. A restart refreshes the radio connection and clears temporary system state without deleting game data.

4. Update the game and iOS

Open the App Store, search for PUBG Mobile, and install any available update. Party members should use compatible game editions and versions; TipsMake's guide to the PUBG Mobile version-mismatch error explains what to check when invitations fail.

Also open Settings > General > Software Update. Install a stable iOS update when appropriate, with the iPhone backed up and connected to power. Do not download modified clients or unofficial update files.

5. Disable VPNs and filtering tools temporarily

A VPN, DNS filter, firewall, ad blocker, or work/school configuration profile can interfere with a game's authentication or server connection. Temporarily disconnect these tools and test PUBG Mobile again. If that fixes the problem, review the tool's settings instead of leaving security controls disabled permanently.

iCloud Private Relay primarily protects Safari browsing, so it is less likely to be the cause of a game-specific failure. Do not change it unless other troubleshooting points to a broader network issue.

6. Try LTE or 5G Auto

Open Settings > Cellular > Cellular Data Options > Voice & Data. If 5G is unstable in the current area, test LTE; if LTE is congested, try 5G Auto where supported. Options vary by iPhone, carrier, and plan.

Low Data Mode may restrict automatic downloads and background tasks. It normally should not block live gameplay, but turn it off temporarily if PUBG Mobile is stuck downloading resources.

7. Use the in-game repair option

If other apps work on cellular data but PUBG Mobile does not, return to the game's login screen and look for Repair. Start with a routine repair and let the client verify its files. Keep the account linked to a supported sign-in method before any action that might require logging in again.

8. Reset network settings only as a later step

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This does not erase photos or apps, but it removes saved Wi-Fi networks and network settings, resets manually trusted certificates, and can remove VPN settings not installed by a management profile. Cellular roaming may also be turned off.

Review Apple's reset-settings documentation before proceeding. Do not choose Erase All Content and Settings.

If the problem remains

• Test a different cellular network or another iPhone on the same carrier.
• Check PUBG Mobile's official service notices and in-game announcements.
• Contact the carrier if all cellular apps fail or the SIM repeatedly loses service.
• Contact PUBG Mobile support if only the game fails; include the exact message, game edition, Player ID, iPhone model, iOS version, carrier, and steps already tried.
