Another report indicates that AT&T had basically eliminated unlimited data plans for new customers previously - this affects those existing customers who were grandfathered in with the so-called “unlimited” plans.
I think that’s actually worse.
Fact is that AT&T hasn’t invested in infrastructure and was unprepared for the influx of customers who sought out iPhones when AT&T was the sole provider with them.
Now?
There’s no reason to go with AT&T when the other providers have them as well.
