User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:36.0) Gecko/20100101 Firefox/36.0 Build ID: 20150222232811 Steps to reproduce: Activate airplane mode. Start FM radio app. Actual results: Cant use the radio because airplane mode is on. Expected results: I would like to be able to disable the SIM card some how so the cell network is disabled, like if you removed the SIM card from the phone, but at the same time be able to use the radio. It seems silly that i have to be connected to the cell network to use the radio. If i removed the SIM card from the phone physically i can use the read while not using the cell network.
