Steve signed up with Spectrum, using Verizon and the best he could get for his iPhone 7 is 3G. Leo says that's terrible. Verizon is much better than that, and it sounds like Comcast is going cheap on buying wholesale data and then reselling it. Also, while you're using Verizon's network, Verizon is giving priority to their own customers. So you get a slower experience. Spectrum is hoping you'll be close enough to an Xfinity Access point via WiFi. But half the time, there's nothing there!
