Le S3 Questions - Wi-Fi settings

[mstrblueskys]

Hey there - I gave my wife my Le S3 after she broke her iPhone this weekend. It's doing well, but today she's at work and I can't go in and fix things for her. I have 2 questions:

How do you 'forget' a wifi network? She needs to reset her connection at work.

How do you enable Wi-Fi calling? I saw it's supported. We're on AT&T.

I'd be able to get it if I had the phone in front of me.

Thanks.

To forget a wi-fi network, usually you go to Settings>Wi-fi, long-press the network, then tap Forget. Wi-fi has to be on at the time. Does it work differently on that phone?
