This is abit long so bare with me
So starting on Friday i noticed some apps and websites failed to load or loaded very slowly when using data. Over wifi those apps/sites worked fine. I rebooted phone and still the same. Confirmed with o2 i didnt have age restriction on my account. Also i was travelling alot over the weekend so isnt restricted to my local mast
I Googled and check things like Twitter, downdetector website and also this and Giffgaff forums and a few others from all over the UK reported the same issues - some apps and sites not working on data but fine on wifi. Some reported going into 3G fixed it and it does to some degree. I went from 4G to 3G and the app works. Back to 4G and it fails to load. . Ive seen tweets, forum posts and reddit threads all reporting similar issues over the past 24hrs
It very random too. Apps that worked yesterday day, failed to work in the afternoon only to work again in the evening. Only one that consistently doesnt work on data is the reddit app. These forums are slow on data too but fine on wifi
So it seems there is some nationwide issue effecting some o2 users
