Verizon, WHY did you intentionally remove the ability for wifi calling in airplane mode in the N910VVRS2CQA1 update?! I get a very low signal for making/receiving calls in my place. In order to make decent phone calls and send/receive sms/mms, I normally put my phone in airplane mode, turn wifi back on and was always able to place calls and sms/mms via my home wifi network. Ever since latest update, you are blocking this now. Am receiving the error message about 'radio being turned off', thus blocking wifi calling.
