How do you do 2FA? Bank wire confirmations?

Never need Google Maps? No whatsapp and messenger to talk to friends and family?

I'd love to be smartphone free but fail to see how I could do without those uses

Dumb mobile phones still have SMS, so 2FA still works and since it is a telephone, talking to friends and family is also possible. I suspect the reasons the OP gave up on the smart phone was to get away from all of those phone apps.

You probably shouldn't use SMS based 2fa. It's much worse than the alternatives.

While SMS-based 2FA may be worse than the alternatives, it is clear that the previous commenter has decided that having a smartphone is much worse than the alternatives.

Unless their financial institution offers a non-smartphone 2FA option, such as a PIN-based card reader[0], having to use SMS-based 2FA is a reasonable price to pay.

For wire transfer there are still alternatives although becoming more and more difficult unfortunately. Other things one can still do without a smartphone, and the benefits outweigh the cons (for me at least).

My mother has a dumbphone too. Sweden is soon shutting down the 2G and 3G networks so then it will certainly be quiet.

I don't have the full overview, but there are new "dumb" phones made that has 4G/5G, no? (Nokia 8210 seem to be one example, Punkt MP02 another)

But is Edge still available then?

i suspect most countries will reatain 2g services as a fallback and for old infrastructure components

No

Source for the 2G closure? 3G is getting silent in many areas but I've understood 2G usually stays to provide calls & sms in low coverage areas.

Interesting, thanks. How will they cover the northern Sweden, I wonde.

Me does too. The coverage looks better than expected for 4G though so we will see how it actually works in the mountains...
