If you want to join the smartphone-free club, here's my how-to guide:
You can replace the most useful functions of a smartphone by purchasing:
1) A dumbphone. These are usually cheap, small, and have batteries that last a week or more. I've mostly had 'rugged' ones which are waterproof and resilient. My current one is a Samsung B2710 that I got cheap on ebay, but you can buy a decent enough dumbphone for £20-30.
2) An old-school sat nav. One of the most useful things about smartphones is 'Google Maps' - almost everyone uses it. But standalone sat navs do the job just fine, and many modern cars have built-in ones.
3) A pocket camera.
4) An mp3 player (if your dumbphone doesn't handle music).
(all of the above can come in at less than the cost of a typical smartphone)
Next, you need to know that Telegram has a fully-featured desktop app that doesn't require a smartphone. Last I checked you can set up and/or access an account with a dumbphone. If that's changed and no longer works, you can use
Kotatogram to get in, then switch to Telegram if you prefer.
The only real problem I come up against is banking (particularly when I briefly inherited a business bank account with Starling that required a smartphone app). There are still some bank accounts which you can sign up for and manage without a smartphone.
You also can't use Whatsapp without a smartphone. But if you have friends that stubbornly and exclusively communicate using that app, then they're not exactly that great, are they.
Everything meaningful you can do with a smartphone you can do with a desktop PC or laptop. And the great thing is - you choose when to go to it and do your business. It doesn't follow you 24/7, nagging at you for attention.
There's a feeling of pride and self-worth when you're stood waiting for a train or sitting at a restaurant, knowing that you're able to take in the world around you like past generations did, instead of weakly and instantly pulling that computer out of your pocket through some nervous need to be doing anything other than thinking and observing. To be able to sit down for a good film without checking what inane bullshit is occurring elsewhere in the world. To walk in nature without spoiling it with all the world's problems and perversions. You'll find more peace, less distraction, less noise, less misery. The smartphone-free man is superior!
Go forth and be free(r)!
