You absolutely can! Ive been doing something similar.
Two devices - one that’s a mini computer, and the other is a phone.
That mini computer is a old phone without a network plan. And if it doesn’t have wifi, I can’t jump onto social media or anything. Which is pretty nice as I’m reading books or writing on that device with “less” distractions. And if I get a text message, i quickly check it on my phone and put it away.
