When I first moved to my current address I had no signal when indoors, this was with 3 mobile. Virgin were offering me a good deal at the time so I accepted it, when I called 3 to cancel they offered me a free signal booster if I sign a new contract with them but I declined.
For over two years I have now been with Virgin Mobile and had the same issue which isn't great as I am often on call. I recently discovered while being visited by a friend that his Vodafone has full signal when he visits me. A check on the ofcom site also confirmed that only Vodafone and O2 give good indoor signal in my area
I am now, as a result looking to move to Vodafone after changing all three of my Virgin Mobile contracts to 'rolling contracts'. Is the signal booster something that Virgin will offer to keep me on, for which I would happily sign a new contract, or is now the time I change to Vodafone?
