Should I install iOS 18 Beta on my only iPhone?

Hello,

I have just watched the WWDC24 Film, and I saw that the beta was already out. I would like to install this iOS on my iPhone because I don't think I could wait, but I don't want my iPhone going wrong. I have only 1 iPhone set up on my Apple ID, and I really want this iOS on my iPhone. I have heard people say that you should only install beta iOS on secondary iPhones, not your most important one.

I also don't know how to install the beta version. I don't want to pay for this update. I would like this update to I can enjoy the features because, as I said before, I don't think I could wait until July. I have already looked in my iOS Update settings and there is nothing but Automatic Updates.

Thanks,

Noah
