4. Update PUBG Mobile

In case you’re still running the outdated PUBG Mobile game on your mobile device then it may cause compatibility issues and lead to server connectivity. To do so:

For Android:

  • Open the Google Play Store app > Tap on the hamburger menu icon.
  • Next, tap on My Apps & games > If the PUBG Mobile game update is showing.
  • Tap the Update button next to the app > Wait for it to install.
  • Once done, open the game to check for the issue.

For iOS:

  • Open the Apple App Store application on the iPhone.
  • Now, tap on the Profile Picture icon from the top-right corner.
  • Scroll down a bit to see which apps are available for update.
  • Check if the PUBG Mobile game update is showing or not.
  • Then tap on the Update button.
  • Wait for it to complete and launch the game.

5. Clear Cache and Data of PUBG Mobile

Another thing you can do is clear the app cache data and the storage data by following the steps below. Sometimes corrupted app cache data might trouble you a lot.


Please Note: There is no option to do this on iPhone. Only a simple restart will do the job.

  • Go to the device Settings menu > Tap on Apps & Notifications.
  • Now, tap on See All Apps > Select PUBG Mobile under the App info section.
  • Clear Cache and Storage (5)Tap on PUBG Mobile to open the app info page.
  • Tap on Storage & Cache.

6. Disable VPN

Try disabling the VPN service on your mobile if you’re using it to play PUBG Mobile. We all know that so many players prefer using VPN services to connect to a different region server which easily allows them to play PUBG Mobile without any geo-restrictions. However, VPN services can eventually cause ping delay or higher latency while connecting to the game servers. So, it’s better to temporarily disable the VPN to check if the game servers responding properly or not.

7. Close Background Apps

Do not store too many background apps running on your mobile device no matter how well your system is optimized for memory management. Keeping the applications alive in the background can consume too many system resources including the data bandwidth which might affect the overall server connectivity with PUBG Mobile. So, head over to the Recent interface > Tap on Clear All to close all running apps.

8. Try to Log in Multiple Times

It’s recommended to try logging in multiple times at your end even if you’re getting kicked out of the server connectivity. The maximum number of active players on the server might prevent other players from getting into the game.

9. Contact PUBG Mobile Support

You can try contacting PUBG Mobile Support to submit the ticket regarding the issue. We expect that the support team will soon come up with a solution for you.
