I have a older iPhone, my signal was weak so I added the wifi calling to my phone. It asked me a bunch of questions and then my Fido cellular data options disappeared on my phone. Now when I got to my iPhone settings and click cellular the page is blank. I have tired re starting my phone, re setting my network settings and nothing has changed. The Fido and Apple stores are closed, and I need my phone! Hope someone can help. I am not at home so I don’t want to reset my whole phone because I have not backed up in a while.
