Is it safe to install public beta 11.2 on my iPhone X even tho I don't have access to a computer?

Is it safe for me to install iOS Public beta profile, and then install iOS 11.2 beta on my iPhone X? I don't have a computer anymore so I'm just wondering if there was any aspect that I would need a computer for before/during or after installation? Back when iOS 10 was the main one I had the iOS Public beta 11 installed on one of my iPhones and did it all on phone and never had an issue, but this time around I'm messing with alot more expensive device in the iPhone X, and don't want to void any warranties or have an unusable device if a computer were to be needed and I didnt know before hand.
