That’s the reason why every other fucking country still has either 3G or 2G activated. 4G is just a shitshow for making calls.
Well, 2G and 3G are being shut off in the United States as well. I believe AT&T shut down their 2G network in 2017 and shut down their 3G network here recently. And T-Mobile in the United States shut down their 3G network in 2022. And while their 2G network is still currently running, it won’t be forever. I believe Verizon is also in the process of shutting down or has already shut down 2G and 3G as well.
Where I live, 3G is going to be phased out, but 2G is staying seemingly indefinitely. Not only for the old phones, not only for all the dying villages that are not getting any upgraded equipment, but also for all the automation dependent on it. Apparently quite a few places did it like this.
