@James187 Hi there, I get your frustration, coverage dropping can be very frustrating and I'd love to help you out here. To do that, I'll need a bit more info. Tell me, whereabouts is the factory located? Is this affecting your calls, text and data? Is there anyone else in the building using Three that you know of that experience the same thing? The more info I have the better. Also, be sure to take a look at our All about: Phone Coverage blog for some great tips and tricks 👌
