I'm on Vodafone and have experienced this many times on my Z10 and now occasionally on Z30. I think it get stuck while switching between 3G to 2G and vise versa.
But, Z30 does a solid job on signals. At my work, which is away from main city area, its a dream to have a proper working 3G signal. Everyone at my office switch to '2G Only' the moment they stepped in, just to save juice and to avoid call drops. Be it a Android, iphone. But Z30 shows how powerful paratek antenna is !! now with Z30, I can log in to CB forums in most of my office areas. I had never been able to get the 3G signals on my Z10 there.
