I did exactly that many years ago. Ditched my phone and went with x86 UMPC with builtin 3G modem, the name of which I don’t remember because it was some random Chinese no-name. Unfortunately that experiment coincided with the era of “fuck websites, we’re going app-only because we’re so hip”. I was in a world of pain right off the bat when I got a carrier plan, specifically marketed for usage on PC’s, and it did not work. I called them and said to me:

• Do you have android or iOS?
• I only have windows
• Windows phone?
• No, Windows 8
• Well, you’ll have to use the app to activate the SIM card…

Turns out, the usage on PC’s meant tethering…

Lots of online things, if they were even available as websites, were highly cut down versions of apps. And SMS 2FA, goddamn. I remember not being able to buy booze and shoes because, apparently, phone confirmations were required in those establishments. Good thing they’re fading out in favor of TOTP and passkeys. But, at a time, I had to swtich to a carrier that allowed me to use “corporate” features like SMS forwarding and SIP telephony. Also, fuck WhatsApp, that shit can burn in all fires of hell.

On the other hand, I really miss that time. It was liberating, just not having like, a few dozen malwares in my pocket tracking me down just to track someone’s dog, or a bus, or to spy on someone’s buying preferences or whatever. But things have gotten quite a bet better over the years, so I’m kind of inclined to repeat the experiment with my new-ish OM3S which I carry because I still cannot imagine going out without a proper PC on me (don’t buy it, though, it is severely underpowered, better get something GPD instead).
