MacRumors reports today that AT&T has written to those of its customers who have grandfathered unlimited data plans for their iPads, telling them that, for all intents and purposes, their plan will no longer be unlimited from May 24, 2017.
What this means, essentially, is that from that date onwards, AT&T iPad unlimited-data customers will have their data usage throttled when they use more than 22GB of data during one bill period, or, as AT&T put it in its letter, “when you use more than 22GB of data in one bill period, we may slow down your data speeds during periods of network congestion for the rest of your bill period.”
Despite the fact that this ties in with AT&T’s recently announced unlimited data plan policy, it will come as a bit of a shock to iPad owners who have been used to having completely unlimited and uncapped data.
