I think a better approach would be to query the PackageManager to detect if Telephony features are even available on the device. A device should only have Telephony features if it has a phone.

PackageManager pm = getPackageManager();

if (pm.hasSystemFeature(PackageManager.FEATURE_TELEPHONY)){
    //has Telephony features.
}
