|Not receiving signal from the cellular network
The cellular signal is too weak to boost.
Check the connection between your donor antenna and Cel-Fi SOLO. Confirm that your antenna is properly connected and working. You may need to try another donor antenna.
Using your cellular device, try to find a location with at least one consistent bar of 3G or 4G. More bars is always better! Once you have found a usable signal, place your donor antenna in this location.
