Hi Jerrod,
One thing you need to be aware of if you're talking about removing the cellular data antenna is that you may disable your phone's ability to make phone calls. It all depends on what network you're on. For GSM networks like AT&T, the voice and data are carried on separate channels. However, on LTE networks, the voice is converted to data and carried over the network data channel. Same idea as Voice Over IP, or VoIP, only in this case it's VoLTE. So on things like Verizon, killing the cellular data will also kill your ability to even make a phone call.
