I’m trying to download safari on my iPhone, is that possible? When I have to open a portal for my doctors it says I need Safari?

The Safari app should already be installed on your iPhone. There shouldn't be a need to download it. If you are running the very latest version of iOS 14 on your phone, it already has the latest version of the Safari app.

If you have iOS 14.7.1 installed then you already have the latest Safari.

If not, you can install iOS 14.7.1.

Check your iOS version in Settings > General > About > Software Version > here?
