Technically? I suppose so, although the device would have to spoof
your phone's preferred carrier to get the phone to connect. But in
practice, there's no way this would happen since the frequencies in
question are licensed to the cell carriers, and they would not be at
all amused at freelance low-power competition that would steal their
calls.

WiFi is different, since it uses the same unlicenced band as 2.4MHz
cordless phones. For that matter, why screw around with WiFi? Just
make it a cell/cordless phone.
