I suggest potentially moving the router in the house to a place where you get 4 bars or more even if that's a negative to your WiFi coverage. If you're in a two story place, higher the better. Surely there's a way to see within the router way LTE band you're connected to? Band 3 (1800Mhz) is the band you want it to lock into for 3Mobile's network.
