The LTE network isn't good. I have LTE SIMs from both and they don't always work since the base stations are spaced too far apart. They also just put these in areas where they (the networks) think their users would be to save on cost hence the switch to 3G signals when you're in some other parts of the city. I sometimes wonder if their bandwidth speeds just meet the bare minimum requirements since our 4G feels like 3G abroad and our 3G is like Edge from overseas.
