Poor signal or poor voice quality for 4G LTE calls
For the best 4G signal, the Telo 4G Adapter should be placed in an area of your house with good cellular reception such as in a room with a window. It should ideally be located as close as possible to a window. Suction cups may be used to mount the adapter directly against a window. The adapter should not be placed in a corner, against a wall, or within five feet of a large metal object like a water heater or refrigerator.
