iPhone XR or above (New Monmouth area Middletown)

I'm looking for an iPhone XR or above model. It can be in pretty much any condition, as long as it works. I want to use it for my mom - it doesn't need to be able to go online, in fact I don't want it to - I literally only want her to be able to use Siri to set an alarm or a timer using her voice. It will basically be a glorified alarm clock; I just can't find an alarm clock that does exactly what I need it to. Thank you! (Only XR or above is capable of doing this offline, that's why I asked for that model or above.)
