Firmware update to 2019.204.4 appears causing this problem. There used to be no need to pull out the card as long as I carry with me iPhone with Tesla app. Is there remedy for it?
Try restarting the car (hold down both steering wheel buttons for a second). Also try rebooting the Tesla app by logging in and out. If it still doesn’t work, take it in to a service center, this is not a common bug.
I have found that the bluetooth was turned off. I have been just back from oversea trip for two weeks and during which I turned off the bluetooth.
Thanks eveyone for your helps.
