Use TelephonyManager.getPhoneType (). Returned values are 

PHONE_TYPE_NONE
PHONE_TYPE_GSM
PHONE_TYPE_CDMA
PHONE_TYPE_SIP

Checking if CDMA or GSM should work

You can probably just check for the presence of a mobile network type.

boolean hasRadio()
{
     ConnectivityManager connManager = (ConnectivityManager) getActivity().getSystemService(Activity.CONNECTIVITY_SERVICE);

     return (connManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE) != null);
}
