is it (financially) worth it?

I've unfortunately had unrestricted Internet access since I was about 7-8, and have developed a pretty serious social media addiction/inability to let my brain sit in the quiet, and as such I've been looking into the Mive Style Folder lately as a way to make it inconvenient to doomscroll (in a way that just setting limits on my phone isn't, because I know I can just override those), but not force me to go cold turkey

as ideal as that sounds, I've been living in poverty my whole life, and I can't even pay my bills without the help of the benefits I'm on, so I can't afford to just throw my perfectly working Samsung out in favour of something that might not even help me

so my question is this: is it financially worth it to get a flip phone? once my contract is up in March I can hypothetically "flip" (ha ha) my S23 and break even on a Mive, but I've never replaced a working phone before and even with the benefits I know I'll almost definitely have, I'm second guessing myself
