I'm currently with Tesco on the O2 network and looking at a new phone deal. O2 aren't the most competitive for what I'm interested in. Does anyone know please what the most accurate site for showing coverage is please. My neighbours confirm that Vodafone is not great - the Ofcom map suggests voice coverage but not data is available as a control check
Any advice appreciated
