All our plans are not throttled. Excluding the AT&T Premium plan, all plans are subject to deprioritization if you are connected to congested tower. Speeds are slowed down temporarily and go back to normal when congestion is over, or you move to another area. The speeds during deprioritization vary with congestion. Most of our AT&T based customers use over 750GB with no deprioritization at all. If you want plan that is not subject to deprioritization even, then consider leasing our AT&T based premium plan.
