How do I turn on the ringer for my iPhone 8 SE?
iPhone SE, iOS 14
There is no such thing as an iPhone 8 SE. However, if you have an iPhone 8 or an iPhone SE, it is turned on by pressing the power button on the top of the phone. If it is an iPhone 8, it is the power button on the side of the phone.
If you are experiencing a problem where the iPhone will not turn on, then see the instructions in this support document. If your iPhone won't turn on or is frozen - Apple Support
