front license plate depends on state you are in. I know if you are issued 2 plates it is the law to have one on the front and the rear. You might get away without the front one for a while but it is just a surefire reason to get pulled over by the cops. they generally use the no front plate as a starter and find other shit that is illegal
I dont know why you would want a license plate frame. I hated the dealer one, I wasnt getting paid to advertise for them and they certainly didnt give me any discount to drive with it on so it came off ASAP
