I know I'll receive a lot of vote-downs because of this post, but I dont really know what has happened and where I am no one can help me.
I am in China and my Huawei (European) phone has worked just fine on wifi, but after 2 months I topped it up and the message came that I have data now, but I cant use anything. It shows that there is inbound traffic, but nothing seems to go outward. The APN settings look just fine. Huawei recently has come up with an update of their ROM. I am wondering if that can be the source of the problem.
Any ideas why? As you can see the arrow is grayed out. It's just weird.
