Lots of providers claim to offer Unlimited service. Over here, Sky Broadband claims to be unlimited. But they also have Fair Usage Limits so it's only unlimited for the first X GBs and then you are blocked or throttled. It's all a marketing ploy. It only seems unlimited to the vast majority of users who will never reach the fair usage limits.
If some subscribers have to "hack" their phones or install apps that mask their data usage, then they clearly know that they are breaking the terms of their contract and they cannot be defended. What I don't understand is how they think they can get away with it. The operator keeps records of all data usage (quantity, not content) and will know how much each subscriber has used and will very easily find those who are breaching the limits. All operators have Revenue Assurance teams whose job it is to look for these kinds of revenue leakage.
