FM radio disabled by some U.S. Carriers

I finally got fed up with U.S. carriers turning off the FM chips in a lot of their smart phones. I just started a petition on the White House petitions site, We the People. Will you sign it? http://wh.gov/iPm2L

U.S. Cellular LG G3 can't send text messages or call but can use mobile data?

My LG G3 has suddenly stopped being able to send messages and call, but I can sometimes use mobile data. Every once in a while I will get a Phone Activation popup when I power on my phone but I never wait to see if it will actually do anything. When I looked at my phone info it said I didn't have a mobile number. Is this SIM card related or software? I am on 5.0.1 stock unrooted.
