Unable to log in to Pokemon GO through mobile data but WiFi works [duplicate]

I've been experiencing the exact same problem and finally figured out what was causing this. Turned out I had disabled Google Play Store from using background data when not on WiFi, enabling this option allowed me to login without WiFi consistently.

Here's how I fixed this, hope this helps others.

Go to: Settings - Wireless & networks - Data usage Scroll down to and tap: Google Play Store Uncheck: Limit background data

Check to see if your Google Services has restricted background data, I unchecked my one and started working. You can do this the same way as the Google Play Services one.

I had the same frustrating issue for about 3 weeks. Could login to Pokemon Go every time through WiFi but gets stuck on the login screen every time through mobile network. What finally worked for me (Sony Z1 compact) was going to App --> Reset app preferences.

If you still can't use mobile data to login, you could try this method. Which works for my sister LG G2

Firstly, turn on mobile data, and turn off wifi

Go to settings, then to account, turn on auto sync (if didn't turn on yet)

Then click on your gmail, choose to manually sync which item, you can leave it auto sync all your stuffs

But the most important is the 'app data'. Make sure you click on sync once

If you already auto sync, try click sync at the 'app data' while on mobile data

You can try, and hope this helps

Using Samsung Note3 = go to Setting > Connection > Data Usage > press 'left - after MENU button' > Restricted Bcground Data > OK > 'UN-ticked'

I had exactly the same issue. It looks like I accidentally disabled Google Play Services from using Mobile data.

Go to Settings - Apps - Google Play services - Data usage - check "Mobile data".

I finally found how to fix this.

I've tried all this options and nothing worked until now

?Resetting app preferences ?Allowing less secure apps ?Restarting / Reinstalling ?Allowing background data

Nothing of this worked for me. What solved my Problem was going to the " Google-play service" and deleting all data and cache. AFTER THAT I went to Google location history and ACTIVATED the location history. It had some kind of bug which deactivated every time after I left the screen, so I had to complete deactivate for all my devices and activate again. It was showing that my device last connection was "unknown", it now shows the correct date. In a galaxy s7 you will find that option when you go to "options->google->location->Google location history".

I hope that helps. Bye.

I had the same problem. I fixed it by removing data restriction from google account manager.
