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.
Counterpoint - younger generations grow up in the same poverty as their parents (so that any subscriptions are unlikely) and even if they don’t - their media needs may not fully align with what their parents would buy. So children in my experience do find ways to pirate. Maybe not the best ways, but still.
