Technology Headaches

Technology is wonderful....when it works. Up at my mum's place, she must live in a mobile signal Black Spot. Even on a good day there is flat out being one bar of signal - often phone calls won't come through, or if they do they drop out again....but usually it can manage a text. This is the new wireless device I just bought on the way up there, but can't even get to test it out properly. GRRRRRR!
