No one here has mentioned ( Its Been Announced for USA ) that the UK 3G networks will be shuttered ie closed down here in the UK.
Just received txt message saying
Vodaphone will close its 3g network in 2023 ( no idea about other networks ).
3g phones will then switch back to 2g ie Text and calls only.
So Current 3g smart phones get a lobotomy and become Dumb but still working ).
with the current price of 4G and 5G phones being outlandish guess its time to save for a new phone.
ps if and when i upgrade i'll want one with a replaceable Battery none of this built in and sealed crap (non user replacable )
3G will shut down in 2024 here in Au.
They've been doing a per-frequncy staged shutdown for a few years now, leaving just the 850/900Mhz bands still working for calls and text (also, making them look slower vs 4G/5G)
I think just one telco (Optus) will keep 900Mhz 3G alive, past that date. To answer Knobs question, i assume at least one carrier per country will continue basic, low bandwidth support for such devices.
(Fun fact, optus had $2 a day, unlimited data SIM Cards. They never put an end date to the offer, and people STILL sell them for hundreds of dollars and recharge the credit using the original owners details. We dont get unlimited mobile data here, and before the 3G network began to shut down you could get 50Mb/s out of them. These days some numpty still tries to sell them and get their money back, when they get <5Mb/s)
While it kinda feels too soon, 4G/LTE has been around a long time already, 10 years here in Au.
Those of us who upgrade slower or live in regional areas, it feels a lot less.
I view the disconnected devices as being wifi tablets, after that point. Media player, MP3 player, raspberry pi wannabe... they arent useless, just less useful.
