Thanks for the replies, I toggled it on and off. I haven't had any phone calls since then so I don't know if it stuck.
The only other problem I've had so far is it won't send MMS messages when the Wifi is turned on. After I turn it off (while the message is still trying to send) it takes forever to go through on 4G. I tried searching that one and I didn't find any posts about since the 4.3 update.
