This question already has an answer here:

I cant login on pokemon go with my 4g, but when I login with wifi I can walk away with 4g and the app works perfectly fine.

Although you do not always have internet accesable, I need to be able to login with 4g :-)

I have a huawei y6 pro Android system: 5.1 I have tried restarting the app, my phone, reinstalling ....basically the basic stuff

    If your previous question is closed as off-topic, asking it again is not the correct course of action. – Vemonus Aug 1 '17 at 19:50
  • Guys coman, I have already read all other articles about this, but they do not help... well well if you say so, a fallen brother will go away – Daniel aakhus Aug 1 '17 at 19:54
  • I disagree that this is a duplicate of the marked question as this is asking for a specific problem with 4G vs. Wifi which is not related to the GO servers. I think the question might have already been asked somewhere else, but the linked question is entirely unrelated. – Chase Sandmann Mar 29 '18 at 15:26

I had this problem as well

Why is it happening?

At the first launch of the app, a setting must have been selected automatically that restricts data access to the Pokemon go app.

How to fix

Go to:

  1. Settings of the phone
  2. Go to the apps section of your settings
  3. Click on "reset app preferences" in that section, and then launch the app.


This will reset the app preferences for every app, which means that when you launch an app, it will again ask you a prompt for access to a certain feature on your phone. For example, Gallery will ask for permission to your photos the next time you open it.

  • Bit it seems it dosent work, and the example, the gallery, does not ask for permission either. I deleted all data relater to pokemon go, bit i still cant login, bit i will try your method when i get wifi – Daniel aakhus Aug 1 '17 at 21:13
  • @Danielaakhus did you click on reset app preferences? – Assafi Cohen-Arazi Aug 1 '17 at 21:14
  • Yes, but notting happened... – Daniel aakhus Aug 1 '17 at 22:08
  • @Danielaakhus That's weird. That button should reset app preferences for EVERY app, including gallery. Try googling how to reset app preferences on your specific device – Assafi Cohen-Arazi Aug 1 '17 at 22:09
  • This discussion is a rather apt example as to why we don't allow re-asking the same question. – Frank Aug 1 '17 at 22:23
