The signal in our area is terrible indoors and Tesco can't do anything about it (used to work fine, something happened last year which caused the loss but they believe we never had good signal... But we did). Customer relations aren't aware of any booster that works on their network as they piggyback off O2, so they've offered to allow us out of contract, however EE is our only other option with coverage and it's way more expensive. So I'm hoping to discover an alternative way to stay with Tesco and get signal at home. Any advice or suggestions much appreciated!
