OK, I've been having an "issue" with my N5. I'm not sure if it's N5, Vodafone or Vodafone SureSignal related, but here is what I've been seeing.
Out and about, all is well. Come home and I'll notice that I'm getting no data updates. Check the phone and I've got a full signal, just no data signal - no 3G, no H, just a full-bar mobile signal.
A total restart of the phone and back comes the data signal.
Now at home I do use a SureSignal, so not entirely sure where the issue is.
I am however 99% sure that the same has happened to me when I'm out and about. Maybe I've moved from one cell tower to another, but I'll look at the phone and see if I've got a signal, but no data. Off/on with the phone and there is the data once more.
As I said I don't know ehre the issue lies, if it's the N5 or if it's Vodafone messing me about (wouldn't be surprised there - will possibly be looking for a new carier early next year).
