Over the last few weeks I have noticed that the mobile data on my E5 Ubuntu phone keeps on dropping out, to the point that it is becoming increasingly unusable. I know that there have been issues raised about the WiFi. However, I am not sure if anyone else is experiencing issues like this with their mobile data. When my data goes the only thing I can do, to get it back is to put the phone into air plane mode and then turn it off again. This always brings the mobile data back. Even when I am in the same place and the data signal originally was lost.
As an example; the other day my wife and I were enjoying breakfast in a coffee shop. We were sat by the window and she had full data. I had none. We are both on the same network. I turned on air plane mode and then turned it off again and the my data came back. It stayed on for a minute or so and then went off again. Air plane mode activated again and the deactivated and mobile data was returned. During this time my wife had continual signal on her Samsung S3.
