I am with Vodafone. I used to have a good signal in my home, then it dropped recently. Thought it was just one of those things, either the weather or crap phone. I then noticed advertising for Vodafone signal booster for your home. And guess what.. it will either cost me £50 one off fee or £5 a month. Surely Vodafone wouldn't lower the signal to make you buy the booster? Or would they? Any one else have had the same problem with their signal?
