Sim only? A friend of mine has GG. Think it works on the O2 network. She can get reception in the middle of the woods when the rest of us can’t. Don’t know about the pricing. I’m Sim only with Three and I get 12Gb data, unlimited calls and texts, Go room around the world in 71 countries and 'Go binge' which is unlimited free streaming on Netflix, TV Player, Snapchat, Soundcloud, Deezer and Apple Music if you like that sort of thing. Works out at less than £6 a month if you get it through a cashback site. £16 if you buy direct with Three though!
